    • Abstract: Publication date: April 2020Source: IJC Heart & Vasculature, Volume 27Author(s): Christian Kropidlowski, Michael Meier-Schroers, Daniel Kuetting, Alois Sprinkart, Hans Schild, Daniel Thomas, Rami HomsiAbstractIntroductionA combined assessment of different parameters of cardiovascular (CV) risk and prognosis can be supportive and performed with cardiac magnetic resonance (CMR). Aortic stiffness, epicardial fat volume (EFV), left ventricular (LV) strain and fibrosis were evaluated within a single CMR examination and results were related to the presence of hypertension (HTN) and diabetes mellitus (DM).Methods20 healthy controls (57.2 ± 8.2 years(y); 26.2 ± 3.9 kg/m2), 31 hypertensive patients without DM (59.6 ± 6.7 y; 28.4 ± 4.7 kg/m2) and 12 hypertensive patients with DM (58.8 ± 9.9y; 30.7 ± 6.3 kg/m2) were examined at 1.5Tesla. Aortic stiffness was evaluated by calculation of aortic pulse wave velocity (PWV), EFV by a 3D-Dixon sequence. Longitudinal & circumferential systolic myocardial strain (LS; CS) were analyzed and T1-relaxation times (T1) were determined to detect myocardial fibrosis.ResultsEFV was highest in hypertensive patients with diabetes (78.4 ± 28.0 ml/m2) followed by only hypertensive patients (64.2 ± 27.3 ml/m2) and lowest in controls (50.3 ± 22.7 ml/m2; p

           Honduras: An epidemiological perspective

    • Abstract: Publication date: Available online 4 February 2020Source: IJC Heart & VasculatureAuthor(s): Eleazar Enrique Montalvan Sanchez, Samuel Alejandro Urrutia, Aida Argentina Rodriguez, Gabriela Duarte, Axel Murillo, Ricardo Rivera, Artemisa Viana, Daniela Maria Montalvan Sanchez, Eva Ordoñez, Dalton Argean Norwood, Lucia Belem Dominguez, Ricardo Leonel Dominguez, Karla Torres, Carlos Amilcar GodoyAbstractCardiovascular Disease (CVD) epidemiology varies significantly among Low and Middle-Income Countries. Honduras is the Central American country with the highest Ischemic Heart Disease and CVD mortality rates. The aim of this study was to assess the individual CVD risk factors and calculate Cardiovascular Risk Assessment Scores (CVRAS) from the population. Methods: A cross-sectional study in western Honduras. Estimation of CV risk was performed using Framingham, MESA, ACC/AHA-PCEs and ESC SCORE calculators. Results: 38% were male. For men and women respectively; 49% and 48% had self-reported hypertension (HTN), on measured blood pressure only 18% and 30% had normal readings. Diabetes Mellitus was reported in 19% and 22%. Tobacco use was 14% and 3%. Self-reported regular exercise was 39.9% and 25%. Obesity was diagnosed in 24% and 24%. Lipid profile; total cholesterol was ≥200 mg/dl in 63% of subjects. LDL-C was elevated (>100 mg/dl) in 74% of participants, 9% had LDL-C levels higher than 190 mg/dl. Triglycerides were high (>160 mg/dl) in 60%, of these subjects 22% were taking lipid-lowering medications. 52% reported family-history of CVD. The risk calculation for men and women respectively for each CVRAS were; AHA/ACC-PCEs high risk (score ≥ 7.5%) in 62% and 30%, FRS high risk (score ≥ 20%) 46% and 15%, MESA high risk (Score ≥ 7.5%) in 70.6% and 17.7%, ESC SCORE high risk (score ≥ 5% in 32.4% and 11.8%). Conclusions: CV risk calculations revealed higher than rates than expected with consequently reflected on higher than estimated CVRAS. This represents the first report of its kind in Honduras.

Kaess, Stefan Haack, Thomas Mettang, Oliver Vonend, Joachim R. EhrlichAbstractBackgroundRenal artery stenosis (RAS) can lead to hypertension and renal failure. Nevertheless, its treatment by percutaneous transluminal renal angioplasty (PTRA) remains controversial. It is unknown, whether patients with global kidney ischemia (GKI), that means patients with bilateral RAS or RAS with a single functioning kidney, may benefit from PTRA or not.MethodsWe retrospectively analyzed 93 patients with RAS (25 bilateral or single functioning kidney) undergoing PTRA. Patients had refractory hypertension (≥3 medications). Blood pressure, antihypertensive drugs and serum-creatinine were compared pre-/post-intervention and at 1 year’s follow-up.ResultsAt 1 year after PTRA of patients with GKI, systolic and diastolic blood pressure were significantly reduced compared to patients with unilateral PTRA (systolic: −19.1 ± 10.5 [bilateral] vs. −11.4 ± 12.1 mmHg [unilateral], P

           Biolimus-A9 eluting stent: The Biomatrix Alpha™ registry

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Ian B.A. Menown, Mamas A. Mamas, James M. Cotton, David Hildick-Smith, Franz R. Eberli, Gregor Leibundgut, Damras Tresukosol, Carlos Macaya, Samuel Copt, Sara Sadozai Slama, Hans-Peter StollAbstractBackgroundThe biolimus-eluting stent (BES) was the first to elute anti-proliferative drug from a biodegradable polymer. In the randomized LEADERS trial, a stainless steel BES showed non-inferior efficacy compared to a sirolimus-eluting stent and a long-term safety advantage. We report the first clinical efficacy and safety outcomes of a new thin-strut cobalt chromium biolimus-eluting stent (CoCr-BES) from an international multi-centre registry.MethodsWe studied 400 all-comer patients with coronary disease receiving CoCr-BES at 12 centres, with follow-up at 9 months and 2 years. The primary endpoint was incidence of major adverse cardiac events (MACE) at 9 months comprising cardiac death, myocardial infarction (MI), and clinically indicated target vessel revascularization (ci-TVR). Key protocol elements were the same as the randomized LEADERS trial to enable a historical control for propensity-matched comparison.ResultsMean patient age was 65 ± 11 years, 19% had diabetes, and 55% presented with unstable angina or MI. On discharge, 96% of patients were on dual antiplatelet therapy (DAPT) and 69% were on DAPT at 9 months. MACE at 9 months occurred in 3.9% of patients, cardiac death in 0.8%, MI in 1.1% and ci-TVR in 2.7%. One patient (0.25%) experienced definite or probable stent thrombosis (ST). A propensity-adjusted comparison showed similar clinical outcomes to the BES arm in the LEADERS trial for the primary endpoint MACE.ConclusionsThe new CoCr-BES showed low rates of MACE, MI, ci-TVR and ST at 9 months, similar to the BES arm in LEADERS.

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Marthe A.J. Becker, Cornelis P. Allaart, Alwin Zweerink, Jan H. Cornel, Peter M. van de Ven, Albert C. van Rossum, Tjeerd GermansAbstractBackgroundSeptal midwall late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging (CMR) is a characteristic finding in nonischemic dilated cardiomyopathy (DCM) and is associated with adverse cardiac events. QRS-prolongation in DCM is also frequently present and a predictor of arrhythmic events and mortality. Since the His-Purkinje fibres are located in the interventricular septum, QRS-prolongation may directly result from septal fibrosis, visualized by LGE. Our aim was to study the correlation of the presence and extent of septal midwall LGE and QRS-duration.MethodsDCM-patients with left ventricular (LV) dysfunction (LVEF 
       
  • Non-vitamin K antagonist oral anticoagulation agents in patients with

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): P.P. Olimpieri, A. Di Lenarda, F. Mammarella, L. Gozzo, A. Cirilli, M. Cuomo, M.M. Gulizia, F. Colivicchi, G. Murri, D. Gabrielli, F. TrottaAbstractBackgroundAtrial fibrillation (AF) is the most common cardiac arrhythmia associated with an increased risk of stroke and thromboembolism. Anticoagulation with Vitamin K antagonists (VKAs) or with novel oral anti-coagulants (NOACs) represents the cornerstone of the pharmacological treatment to reduce the risk of thromboembolism. This study aims to provide real-world data from a whole large European country about NOAC use in “non-valvular atrial fibrillation” (NVAF).MethodsWe analysed the Italian Medicines Agency (AIFA) monitoring registries collecting data of a nationwide cohort of patients with “NVAF” treated with NOACs. Using logistic regression analysis, baseline characteristics and treatment discontinuation information were compared among initiators of the 4 NOACs.ResultsIn the reference period, the NOAC database collected data for 683,172 patients. The median age was 78 years with 19.5% aged 85 or older. Overall, the treatments were in accordance with guidelines. About 1/3 of patients switched from a prior VKA treatment; in the 72.3% of cases, these patients had a labile International Normalized Ratio (INR) at first prescription. The most prescribed NOAC was rivaroxaban, followed by apixaban, dabigatran and edoxaban.ConclusionsThis study is the largest European real-world study ever published on NOACs. It includes all Italian patients treated with NOACs since 2013 accounting for about 1/3 of subjects with AF. The enrolled population consisted of very elderly patients, at high risk of ischemic adverse events. The AIFA registries are consolidated tools that guarantee the appropriateness of prescription and provide important information for the governance of National Health System by collecting real-world data.
       
  • Brugada syndrome: A comprehensive review of pathophysiological mechanisms
           and risk stratification strategies

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Ka Hou Christien Li, Sharen Lee, Chengye Yin, Tong Liu, Tachapong Ngarmukos, Giulio Conte, Gan-Xin Yan, Raymond W. Sy, Konstantinos P. Letsas, Gary TseAbstractBrugada syndrome (BrS) is an inherited ion channel channelopathy predisposing to ventricular arrhythmias and sudden cardiac death. Originally believed to be predominantly associated with mutations in SCN5A encoding for the cardiac sodium channel, mutations of 18 genes other than SCN5A have been implicated in the pathogenesis of BrS to date. Diagnosis is based on the presence of a spontaneous or drug-induced coved-type ST segment elevation. The predominant electrophysiological mechanism underlying BrS remains disputed, commonly revolving around the three main hypotheses based on abnormal repolarization, depolarization or current-load match. Evidence from computational modelling, pre-clinical and clinical studies illustrates that molecular abnormalities found in BrS lead to alterations in excitation wavelength (λ), which ultimately elevates arrhythmic risk. A major challenge for clinicians in managing this condition is the difficulty in predicting the subset of patients who will suffer from life-threatening ventricular arrhythmic events. Several repolarization risk markers have been used thus far, but these neglect the contributions of conduction abnormalities in the form of slowing and dispersion. Indices incorporating both repolarization and conduction based on the concept of λ have recently been proposed. These may have better predictive values than the existing markers. Current treatment options include pharmacological therapy to reduce the occurrence of arrhythmic events or to abort these episodes, and interventions such as implantable cardioverter-defibrillator insertion or radiofrequency ablation of abnormal arrhythmic substrate.

Electrical velocimetry (EV), an impedance cardiography technique, can be used for noninvasive cardiac output assessment. The purpose of this study was to determine the feasibility, reproducibility and accuracy of cardiac output assessment by EV in adults with congenital heart disease (CHD).MethodsCross-sectional study of CHD patients that had simultaneous cardiac output assessment by Fick and EV (using Cardiotronic monitor, Osypka Medical). We divided the cohort into: Group 1 patients (n = 54) had hemodynamic assessment at rest only, while Group 2 patients (n = 7) had assessment both at rest and peak exercise.ResultsEV cardiac output assessment was feasible in 100% of the patients. There was good correlation between Fick-derived and EV-derived cardiac index (r = 0.89, p

  • The progress and controversial of the use of beta blockers in patients
           with heart failure with a preserved ejection fraction

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Xizhen Xu, Dao Wen WangAbstractBeta blockers are a recommended therapy in patients with heart failure with reduced ejection fraction(HFrEF). Beta blockers markedly and unequivocally reduce mortality in patients with heart failure with reduced ejection fraction. However, the beneficial effects of beta blockers in patients with heart failure with preserved ejection fraction(HFpEF) are not well established. In this review, we will assess the evidence basis of the recommendations for beta blockers and discuss emerging concerns about the use of beta blockers in patients with HFpEF. The available evidence for beta blockers is limited and it remains uncertain whether beta blockers have a beneficial role in the treatment of HFpEF in the absence of an alternative indication for their use.

Venkatesh, João A.C. Lima, Kengo Tanabe, Takanori IkedaAbstractBackgroundThe extracellular volume (ECV) calculated by T1 mapping, and tissue-tracking strain using cardiac magnetic resonance (CMR) are useful for assessing the left ventricular (LV) function. However, those parameters are controversial for assessing left atrial (LA) function. This study aimed to investigate the usefulness of CMR to evaluate the LA function using those parameters. Furthermore, those LA function parameters were compared in each LV function.MethodsA total of 65 consecutive patients who underwent contrast CMR were prospectively enrolled (age 55.7 ± 14. 6 years, males 67.7%). Among the 65 patients, there were 15 without hypertension, diabetes, or atrial fibrillation (Healthy group). The remaining 50 patients were divided into two groups according to a left ventricular ejection fraction (LVEF) of 50%. We assessed the correlations between the LV- and LA-CMR parameters among the three groups (LVEF 
       
  • Few with ST-segment elevation myocardial infarction are diagnosed within
           10 minutes from first medical contact, and women have longer delay times
           than men

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Josephine Muhrbeck, Eli Maliniak, Lars Eurenius, Claes Hofman-Bang, Jonas PerssonAbstractBackgroundPrevious reports have questioned the feasibility and gender equality of obtaining a prehospital ECG within 10 minutes of ambulance arrival for patients with ST-segment elevation myocardial infarction (STEMI). The main objective of this study was to investigate the proportion of STEMI patients with a prehospital ECG within 10 minutes of ambulance arrival. The secondary objective was to study the gender differences in delay times in prehospital STEMI care.MethodsThis study was a retrospective study based on 539 patients with STEMI at the investigating hospital. Ambulance and medical charts, as well as the national quality registry “SWEDEHEART”, were reviewed for each patient for demographics and time information.ResultsA prehospital ECG was obtained within 10 minutes of ambulance arrival for 99 (29%) of the men and 19 (14%) of the women, p = 0.001. Women had a 2 minutes longer delay between ambulance arrival and prehospital ECG (95% CI 0–4 min, p = 0.018) than men. Women also had a significantly longer patient delay. None of the other time intervals differed among men and women.ConclusionsOnly for a minority of patients is a prehospital ECG taken within the recommended ten minutes from ambulance arrival. Women have longer patient delay times, as well as delay times to the acquisition of a prehospital ECG than men. Improvements of prehospital ECG acquisition and adjustments of the guidelines are warranted.
       
  • Resheathing of self-expanding bioprosthesis: Impact on procedural results,
           clinical outcome and prosthetic valve durability after transcatheter
           aortic valve implantation

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Joelle Kefer, Frederic Maes, Jean Renkin, Shakeel Kautbally, Christophe De Meester, Marine Delacour, Anne-Catherine PouleurAbstractBackgroundNew transcatheter aortic valves were recently developed, enabling to resheath and reposition the prosthesis. The aim of the present study was to investigate whether the resheath manoeuvre did not impair the outcome of patients and the bioprosthesis durability after transcatheter aortic valve implantation (TAVI).Methods and resultsOn the 346 consecutive patients (84 ± 7 yrs-old, mean STS 6.7 ± 5%) undergoing a transfemoral TAVI in our institution since January 2008, 170 patients were implanted using a self-expanding valve (SEV). Among those, 39 (Group 1) required resheathing to achieve a successful implantation, while 131 did not require it (Group 2, N = 131). A balloon-expanding valve (BEV) was used in 176 patients (Group 3). Baseline characteristics were similar between groups. Device success was 98%, the rate of in-hospital death was 2%, and the number of procedural complications was similarly low, with no significant difference between groups. The follow-up was complete in 337 of 338 patients undergoing a successful TAVI (781 patients-year). Kaplan-Meier analysis showed that overall survival was 80 ± 2% and 42 ± 3% at 1 and 5 years respectively, with no difference between groups. On multivariate analysis, acute kidney injury, post-dilatation, pulmonary hypertension, porcelain aorta and STS score, but not resheath, were independant predictors of death after TAVI. The annual event rate of structural valve deterioration was 0.6% patients-year, and similar between groups.ConclusionsOur study shows that SEV resheath did not impair the procedural results, the outcome of patients nor the valve durability at short term after TAVI.

Instantaneous wave-free ratio (iFR) is a vasodilator-free alternative for the physiological assessment of coronary artery stenosis. In addition, iFR shows good diagnostic agreement with FFR and an iFR-guided revascularization strategy was non-inferior to an FFR-guided revascularization strategy. However, the clinical usefulness of iFR for the evaluation of a coronary artery lesions with pMI has not been evaluated.Methods and ResultsA total of 200 lesions from 200 patients (44 pMI territories lesions and 156 non-pMI coronary artery lesions) were analyzed retrospectively. Major adverse cardiac events (MACE) were defined as cardiovascular death, non-fatal MI, unstable angina pectoris, fatal arrhythmia and heart failure during 12 months follow-up after the physiological assessment of coronary artery stenosis. iFR was closely correlated with FFR in pMI and non-pMI lesions (r = 0.81 and 0.72; P

One-year mortality was calculated using Pmort30/PRISM and modified SHFM scores, and the predicted scores were validated using the area under the ROC curve. CART was used to develop an algorithm to classify patients based on their mortality risk.ResultsThe discriminatory ability of PRISM categorical score (AUC = 0.701) was not significantly different than the discriminatory ability of modified SHFM (AUC = 0.686) (DeLong's test p = 0.56) but improved significantly with the combination of PRISM (categorical) score + modified SHFM (AUC = 0.740) (p = 0.002). The predictive capability of the CART tree model after cross-validation was 72.2% (AUC 0.631).ConclusionOur study suggests PRISM score performed as well as modified SHFM for one-year mortality prediction. Moreover, the addition of modified SHFM to PRISM score increases discriminatory ability in predicting 1-year mortality in heart failure patients compared to either of the two models alone. Together, when combined in a CART model, they can be used to identify the population subset with the highest mortality risk and hence guide goals of care discussion.
       
  • Is the sigma-1 receptor a potential pharmacological target for cardiac
           pathologies' A systematic review

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Rebecca Lewis, Jiaqi Li, Peter J McCormick, Christopher L-H Huang, Kamalan JeevaratnamAbstractSigma-1 receptors are ligand-regulated chaperone proteins, involved in several cellular mechanisms. The aim of this systematic review was to examine the effects that the sigma-1 receptor has on the cardiovascular system. The interaction targets and proposed mechanisms of action of sigma-1 receptors were explored, with the aim of determining if the sigma-1 receptor is a potential pharmacological target for cardiac pathologies. This systematic review was conducted according to the PRISMA guidelines and these were used to critically appraise eligible studies. Pubmed and Scopus were systematically searched for articles investigating sigma-1 receptors in the cardiovascular system. Papers identified by the search terms were then subject to analysis against pre-determined inclusion criteria. 23 manuscripts met the inclusion criteria and were included in this review. The experimental platforms, experimental techniques utilised and the results of the studies were summarised. The sigma-1 receptor is found to be implicated in cardioprotection, via various mechanisms including stimulating the Akt-eNOS pathway, and reduction of Ca2 + leakage into the cytosol via modulating certain calcium channels. Sigma-1 receptors are also found to modulate other cardiac ion channels including different subtypes of potassium and sodium channels and have been shown to modulate intracardiac neuron excitability. The sigma-1 receptor is a potential therapeutic target for treatment of cardiac pathologies, particularly cardiac hypertrophy. We therefore suggest investigating the cardioprotective mechanisms of sigma-1 receptor function, alongside proposed potential ligands that can stimulate these functions.

Della Bella, E. Lapenna, P. Budera, M. Dalrymple-HayAbstractThe management of non-paroxysmal atrial fibrillation (AF) remains controversial. We examined the efficacy and safety of the 2 stage Hybrid AF ablation approach by analysing the largest series of this technique reported so far.MethodsThe approach aims to electrically isolate the left atrial posterior wall incorporating the pulmonary veins (‘box-set’pattern). An initial video-assisted thoracoscopic (VATS) epicardial ablation is followed after a minimum of 8 weeks by endocardial radiofrequency catheter ablation.ResultsOf 175 patients from 4 European cardiothoracic centers, who underwent the surgical (COBRA Fusion, AtriCure Inc) 1st stage ablation, 166 went on to complete 2nd stage catheter ablation. At median follow up of 18 months post 2nd stage procedure 93/166 (56%) had remained free of AF or atrial tachycardia (AT) recurrence off antiarrhythmic drugs. 110/175 62.9% were in sinus rhythm off all antiarrhythmic drugs at last clinic follow-up (132/175 75.4% including those on antiarrhythmic drugs). 18 patients (10.8%) underwent a further re-do ablation (mean of 1.1 ablations per patient) 105/166 (63%) remained free of AF/AT recurrence off antiarrhythmic drugs following last ablation procedure.Latterly, ILRs have been implanted in patients (n = 56); 60% have remained fully arrhythmia free and 80% have shown AF burden

Kristensen, Rasmus Møgelvang, Paul Blanche, Anders Fink-Jensen, Thomas Engstrøm, Stefan Kääb, Thomas Jespersen, Jacob Tfelt-HansenAbstractPatients receiving psychiatric medication, like the antipsychotic drug haloperidol, are at an increased risk of sudden cardiac death (SCD). Haloperidol blocks the cardiac rapidly-activating delayed rectifier potassium current, thereby increasing electrical dispersion of repolarization which can potentially lead to arrhythmias. Whether these patients are also at a higher risk to develop SCD during an acute myocardial infarction (AMI) is unknown. AMI locally shortens action potential duration, which might further increase repolarization dispersion and increase the risk of arrhythmia in the presence of haloperidol compared to without. Our aim was to test whether treatment with haloperidol implies an increased risk of SCD when eventually experiencing AMI. Twenty-eight female Danish Landrace pigs were randomized into three groups: low dose haloperidol (0.1 mg/kg), high dose (1.0 mg/kg) or vehicle-control group. One hour after haloperidol/vehicle infusion, AMI was induced by balloon-occlusion of the mid-left anterior descending coronary artery and maintained for 120 min, followed by 60 min of reperfusion. VF occurred during occlusion in 7/11 pigs in the control group, 3/11 in the low dose (p = 0.198) and 2/6 in the high dose group (p = 0.335). High dose haloperidol significantly prolonged QT, and reduced heart rate, vascular resistance and blood pressure before and during AMI. Premature ventricular contractions in phase 1b during AMI were reduced with high dose haloperidol. AMI-induced arrhythmia was not aggravated in pigs with haloperidol treatment. Our results do not suggest that AMI is contributing to the excess mortality in patients treated with antipsychotic drugs seen in epidemiological studies.
       
  • Management of patients with newly-diagnosed atrial fibrillation: Insights
           from the BALKAN-AF survey

    • Abstract: Publication date: Available online 28 December 2019Source: IJC Heart & VasculatureAuthor(s): Monika Kozieł, Stefan Simovic, Nikola Pavlovic, Milan Nedeljkovic, Vilma Paparisto, Ljilja Music, Evgenii Goshev, Anca Rodica Dan, Sime Manola, Zumreta Kusljugic, Elina Trendafilova, Dobromir Dobrev, Gheorghe-Andrei Dan, Gregory Y.H. Lip, Tatjana S. Potpara, on behalf of the BALKAN-AF investigatorsAbstractBackgroundBALKAN-AF evaluated patterns of atrial fibrillation (AF) management in real-world clinical practice in the Balkans. The objectives were: to assess the proportion of patients with first-diagnosed AF in the BALKAN-AF cohort and to compare the management of patients with newly-diagnosed AF and those with previously known AF in clinical practice.MethodsConsecutive patients from 7 Balkan countries were enrolled prospectively to the snapshot BALKAN-AF survey.ResultsOf 2712 enrolled patients, 2677 (98.7%) with complete data were included. 631 (23.6%) patients had newly-diagnosed AF and 2046 (76.4%) patients had known AF. Patients with newly-diagnosed AF were more likely to be hospitalized for AF and to receive single antiplatelet therapy (SAPT) alone and less likely to receive OACs than those with known AF (all p

  • Positron emission tomography (15O-water, 11C-acetate, 11C-HED) risk
           markers and nonsustained ventricular tachycardia in hypertrophic
           cardiomyopathy

    • Abstract: Publication date: Available online 20 December 2019Source: IJC Heart & VasculatureAuthor(s): Peter Magnusson, Jonny Nordström, Hendrik J. Harms, Mark Lubberink, Fredrik Gadler, Jens Sörensen, Stellan MörnerAbstractBackgroundThe objectives of the study were to describe positron emission tomography (PET) parameters, using the tracers 15O-water at rest/stress, 11C-acetate, and 11C-HED, with regard to nonsustained ventricular tachycardia (NSVT) in hypertrophic cardiomyopathy (HCM). PET offers quantitative assessment of pathophysiology throughout the left ventricular segments, including the endocardium/epicardium. The potential use PET in risk stratification remains to be elucidated. NSVT provides a marker for sudden cardiac death.MethodsPatients with a validated diagnosis of HCM who had an implantable cardioverter-defibrillator were interrogated at 12 months and independently of PET-examinations.ResultsIn total, 25 patients (mean age 56.8 ± 12.9 years, 76% males) were included and 10 reported NSVT. Mean myocardial blood flow (MBF) at rest was 0.91 ml/g/min and decreased at stress, 1.59 ml/g/min. The mean gradient (endocardium/epicardium quotient) at rest was 1.14 ± 0.09, while inverse at stress (mean 0.92 ± 0.16). Notably, MBF gradient at stress was significantly lower in patients with NSVT (p = 0.022) and borderline at rest (p = 0.059) while global MBF at rest and stress were not. Mean myocardial oxygen consumption (MVO2) was 0.088 ml/g/min (higher in NSVT, p = 0.023) and myocardial external efficiency 18.5%. Using 11C-HED, the mean retention index was 0.11 min−1 and a higher volume of distribution (p = 0.089) or transmural gradient of clearance rate (p = 0.061) or lower clearance rate (p = 0.052) showed a tendency of association of NSVT.ConclusionsThe endocardium/epicardium MBF gradient at stress is significantly lower in HCM patients with NSVT. This provides a novel approach to further refine risk stratification of sudden cardiac death.
       
  • Prevalence, risk factors, and type of sleep apnea in patients with
           paroxysmal atrial fibrillation

    • Abstract: Publication date: Available online 19 December 2019Source: IJC Heart & VasculatureAuthor(s): G.M. Traaen, B. Øverland, L. Aakerøy, T.E. Hunt, C. Bendz, L. Sande, S. Aakhus, H. Zaré, S. Steinshamn, O.G. Anfinsen, J.P. Loennechen, L. Gullestad, H. AkreAbstractBackgroundRecent studies have suggested an association between sleep apnea (SA) and atrial fibrillation (AF). We aimed to study the prevalence, characteristics, risk factors and type of sleep apnea (SA) in ablation candidates with paroxysmal AF.Methods/ResultsWe prospectively studied 579 patients with paroxysmal AF, including 157 women (27.1%) and 422 men (72.9%). Mean age was 59.9 ± 9.6 years and mean body mass index (BMI) 28.5 ± 4.5 kg/m2. SA was diagnosed using polygraphy for two nights at home. The Epworth Sleepiness Scale (ESS), STOP-Bang Questionnaire, and Berlin Questionnaire (BQ) assessed the degree of SA symptoms. A total of 479 (82.7%) patients had an apnea-hypopnea index (AHI) ≥ 5, whereas moderate-severe SA (AHI ≥ 15) was diagnosed in 244 patients (42.1%). The type of SA was predominantly obstructive, with a median AHI of 12.1 (6.7–20.6) (range 0.4–85.8). The median central apnea index was 0.3 (0.1–0.7). AHI increased with age, BMI, waist and neck circumference, body and visceral fat. Using the Atrial Fibrillation Severity Scale and the SF-36, patients with more severe SA had a higher AF burden, severity and symptom score and a lower Physical-Component Summary score. Age, male gender, BMI, duration of AF, and habitual snoring were independent risk factors in multivariate analysis (AHI ≥ 15). We found no association between ESS and AHI (R2 = 0.003, p = 0.367).ConclusionsIn our AF population, SA was highly prevalent and predominantly obstructive. The high prevalence of SA detected in this study may indicate that SA is under-recognized in patients with AF. None of the screening questionnaires predicted SA reliably.

  • Prognostic value of discharge heart rate in acute heart failure patients:
           More relevant in atrial fibrillation'

The aim of the study was to evaluate the impact of admission HR, discharge HR, HR difference (admission-discharge) in AHF patients with sinus rhythm (SR) or AF on long- term outcomes.MethodsWe included 1398 patients consecutively admitted with AHF between October 2013 and December 2014 from a national multicentre, prospective registry. Logistic regression models were used to estimate the association between admission HR, discharge HR and HR difference and one- year all-cause mortality and HF readmission.ResultsThe mean age of the study population was 72 ± 12 years. Of these, 594 (42.4%) were female, 655 (77.8%) were hypertensive and 655 (46.8%) had diabetes. Among all included patients, 745 (53.2%) had sinus rhythm and 653 (46.7%) had atrial fibrillation. Only discharge HR was associated with one year all-cause mortality (Relative risk (RR) = 1.182, confidence interval (CI) 95% 1.024–1.366, p = 0.022) in SR. In AF patients discharge HR was associated with one year all cause mortality (RR = 1.276, CI 95% 1.115–1.459, p ≤ 0.001). We did not observe a prognostic effect of admission HR or HRD on long-term outcomes in both groups. This relationship is not dependent on left ventricular ejection fraction.ConclusionsIn AHF patients lower discharge HR, neither the admission nor the difference, is associated with better long-term outcomes especially in AF patients.

           progression – An immunohistochemical study of coronary aspirates

    • Abstract: Publication date: Available online 25 November 2019Source: IJC Heart & VasculatureAuthor(s): Kartika R. Pertiwi, Onno J. de Boer, Pauline A.M. Gabriels, Allard C. van der WalAbstractBackgroundCoronary thrombosis is a process with unpredictable clinical outcome. Changes of thrombus composition overtime influence tissue repair and stabilization. We investigated rates of cell deaths and cell proliferation at different time points after initiation of thrombosis.MethodsThrombectomy aspirates of 55 myocardial infarction patients were selected and histomorphologically classified as fresh (25), lytic (25), partially fibrocellular (10), completely fibrocellular (10). Paraffin sections were immunostained with anti-(cleaved) caspase-3/Casp3 (apoptosis), Citrullinated histone/CitH 3 (etosis), C-reactive protein/CRP and Ki67 (proliferation) in combination with either Feulgen counterstaining (DNA) or cell markers for granulocytes, macrophages, SMCs, platelets and endothelium. Rates of apoptosis, etosis and proliferation were measured as a percentage of total number of immunopositive pixels versus total number of DNA positive pixels, while co-localization with cell markers was assessed by digital image analysis.ResultsPositive staining of CitH3 was observed more frequently (93%) than Casp3 (70%), Ki67 (79%) or CRP (59%) (p 
       
  • Early post-transplant elevated pulmonary artery pressure predicts adverse
           outcome in cardiac recipients

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Entela Bollano, Bert Andersson, Clara Hjalmarsson, Göran Dellgren, Bledar Daka, Kristjan KarasonAbstractAimTo investigate the prognostic value of early post-transplant hemodynamic measurements on 5-year mortality in cardiac recipients (HTx).MethodsA right heart catheterization was performed in 290 heart transplantation (HTx) recipients at a one-year post-HTx evaluation. To study the effect of post-HTx hemodynamic variables on 5-year outcome, the cohort was stratified into several subgroups. For right atrial pressure (RAP), mean pulmonary artery pressure (MPAP), pulmonary artery wedge pressure (PAWP), and pulmonary vascular resistance (PVR), patients with values from the upper 10th percentile (high), were compared with those with values from the remaining lower 90th percentile (normal). For cardiac index (CI), patients with values from the lower 10th percentile (low) were compared with those with values from the remaining upper 90th percentile (normal).ResultsDeath or re-transplantation within 5 years after the one-year control occurred in 44 patients (13%). Of those, death or re-HTx was related to graft failure in 20 of cases (45%) and non-cardiac causes in 24 of cases (55%). The risk of death or re-HTx was higher in the subgroup with MPAP above 23 mmHg than those equal to or below this value [hazard ratio 3.22, 95% confidence interval (CI) 1.49–6.97; P = 0.003]. The association remained significant despite adjustment for several comorbidities. There were no differences in outcome between subgroups stratified with respect to high versus low RAP, PAWP, CI or PVR.ConclusionElevated pulmonary artery pressure at a first annual evaluation after HTx was the only hemodynamic variable that predicted impaired outcome in cardiac recipients.
       
  • Automated calcium scores collected during myocardial perfusion imaging
           improve identification of obstructive coronary artery disease

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Mirthe Dekker, Farahnaz Waissi, Ingrid E.M. Bank, Nikolas Lessmann, Ivana Išgum, Birgitta K. Velthuis, Asbjørn M. Scholtens, Geert E. Leenders, Gerard Pasterkamp, Dominique P.V. de Kleijn, Leo Timmers, Arend MosterdAbstractBackgroundMyocardial perfusion imaging (MPI) is an accurate noninvasive test for patients with suspected obstructive coronary artery disease (CAD) and coronary artery calcium (CAC) score is known to be a powerful predictor of cardiovascular events. Collection of CAC scores simultaneously with MPI is unexplored.AimWe aimed to investigate whether automatically derived CAC scores during myocardial perfusion imaging would further improve the diagnostic accuracy of MPI to detect obstructive CAD.MethodsWe analyzed 150 consecutive patients without a history of coronary revascularization with suspected obstructive CAD who were referred for 82Rb PET/CT and available coronary angiographic data. Myocardial perfusion was evaluated both semi quantitatively as well as quantitatively according to the European guidelines. CAC scores were automatically derived from the low-dose attenuation correction CT scans using previously developed software based on deep learning. Obstructive CAD was defined as stenosis>70% (or>50% in the left main coronary artery) and/or fractional flow reserve (FFR) ≤0.80.ResultsIn total 58% of patients had obstructive CAD of which seventy-four percent were male. Addition of CAC scores to MPI and clinical predictors significantly improved the diagnostic accuracy of MPI to detect obstructive CAD. The area under the curve (AUC) increased from 0.87 to 0.91 (p: 0.025). Sensitivity and specificity analysis showed an incremental decrease in false negative tests with our MPI + CAC approach (n = 14 to n = 4), as a consequence an increase in false positive tests was seen (n = 11 to n = 28).ConclusionCAC scores collected simultaneously with MPI improve the detection of obstructive coronary artery disease in patients without a history of coronary revascularization.

  • Effect of right ventricular pacing on left ventricular systolic function
           in patients with Tetralogy of Fallot

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Alexander C. Egbe, Maria Najam, Keerthana Banala, Rahul Vojjini, Karim Osman, Deshmukh AbhishekAbstractBackgroundPrevalence of pacemaker-induced cardiomyopathy (PICM) in adults with congenital heart disease is unknown. Tetralogy of Fallot (TOF) is a common diagnosis in the adult congenital heart disease population, and the purpose of this study was to determine association between frequent right ventricular (RV) pacing and temporal decrease in left ventricular ejection fraction (LVEF) from pre-implantation to 2-years post-implantation (LVEFpost-pre) in TOF patients.MethodsWe studied TOF patients that received RV leads only (N = 51) and a reference group of 7 patients with atrial pacing or biventricular pacing. We defined PICM as a ≥10% decrease in LVEF resulting in LVEF 40%) and LVEFpost-pre.ResultsPICM occurred in 2 (4%) of 51 patients in RV pacing group. LVEFpost-pre was +3% (95% confidence interval [CI] 0% to +5%) in the reference group and −4% (95% CI −11% to +2%) in RV pacing group. No significant difference occured in LVEFpost-pre between the reference group (LVEFpost-pre +3%) vs RV pacing ≤20% (LVEFpost-pre +1%) vs RV pacing 21–40% (LVEFpost-pre −3%) vs RV pacing>40% (LVEFpost-pre −5%), p = 0.318. There was also no association between frequent RV pacing and LVEFpost-pre, R2 = 0.307, p = 0.10.ConclusionPICM occurred in 4% of TOF patients receiving RV pacing, and there was no association between frequent RV pacing and temporal decline in LVEF. Further studies are required to determine the long-term impact of RV pacing in the TOF population, and explore optimal treatment strategies.
       
  • The applications and potential limitations of right ventricular volumes as
           surrogate marker in tetralogy of fallot

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Alexander C. Egbe, Keerthana Banala, Rahul Vojjini, Karim Osman, Arslan Afzal, Vaibhav Jain, Sahith Thotamgari, Naser M. AmmashAbstractCardiac magnetic resonance imaging derived right ventricular (RV) volumes are often necessary for optimal timing of pulmonary valve replacement in patients with tetralogy of Fallot (TOF). This practice is based on previous studies that reported preoperative RV volumetric thresholds that predicted postoperative RV remodeling. As a result, pulmonary valve replacements are being performed even in asymptomatic patients based on RV volumetric thresholds that predict complete postoperative RVOT remodeling. Hence, RV volumes are now being used as surrogate markers/endpoints for future cardiovascular outcomes. Unfortunately, there are no studies showing survival benefit for performing pulmonary valve replacement at smaller RV volumes. This review underscores some of the limitations of using RV volumes as surrogate markers for clinical outcomes, and also highlights knowledge gaps about the pathophysiologic mechanism of cardiovascular death in the TOF population.
       
  • Impact of oxidative posttranslational modifications of SERCA2 on heart
           failure exacerbation in young patients with non-ischemic cardiomyopathy: A

We investigated the extent of OPTM of SERCA2 in patients with non-ischemic cardiomyopathy (NICM).Methods and resultsEndomyocardial biopsy (EMB) was obtained in 40 consecutive patients with NICM. Total expression and OPTM of SERCA2, including sulfonylation at cysteine-674 (S-SERCA2) and nitration at tyrosine-294/295 (N-SERCA2), were examined by immunohistochemical analysis. S-SERCA2 increased in the presence of late gadolinium enhancement on cardiac magnetic resonance imaging. S-SERCA2/SERCA2 and N-SERCA2/SERCA2 correlated with cardiac fibrosis evaluated by Masson’s trichrome staining of EMB. SERCA2 expression modestly increased in parallel with an upward trend in OPTM of SERCA2 with aging. This tendency became prominent only in patients aged>65 years. OPTM of SERCA2 positively correlated with brain natriuretic peptide (BNP) values only in patients aged ≤65 years. Composite major adverse cardiac events (MACE) increased more in the high OPTM group of younger patients; however, MACE-free survival was similar irrespective of the extent of OPTM in older patients.ConclusionsOPTM of SERCA2 correlate with myocardial fibrosis in NICM. In younger patients, OPTM of SERCA2 correlate with elevated BNP and increased composite MACE.
       
  • Acute and sub-acute stent thrombosis: Frequency, predictors and features

    • Abstract: Publication date: February 2020Source: IJC Heart & Vasculature, Volume 26Author(s): Sahar Tariq, Rajesh Kumar, Madiha Fatima, Tahir Saghir, Sobia Masood, Musa KarimAbstractObjectivesTo assess the frequency of early (acute and sub-acute) stent thrombosis (ST) after primary percutaneous coronary intervention (pPCI) and to identify its potential predictors.BackgroundST is a serious clinical event associated with a high mortality rate. A very limited data are available regarding the incidence rate of early ST after pPCI and its predictors, especially for Pakistani population.MethodsStudy included consecutive patients who underwent primary PCI. Telephonic follow-ups were made to obtain 30-days outcomes including ST, mortality, and re-occurrence of symptoms. ST was defined as per the standardized definition proposed by the Academic Research Consortium and classified as acute (during the procedure) and sub-acute (within 30 days).ResultsA total of 569 patients were included with 80.5% (485) male patients. The stent thrombosis (acute or sub-acute) was observed in 33 (5.8%) patients out of which 3 (9.1%) were definite ST while remaining 30 (90.9%) were probable ST. Patients who develop ST were predominantly male, hypertensive, diabetic, with reduced pre PCI LVEF (%) and Killip Class. A significantly higher in-hospital mortality rate was observed in patients with ST as compared to without ST, 36.4% (12/33) vs. 0.2% (1/536); p-value
