Abstract
Abstract Sex differences in hypertrophic cardiomyopathy (HCM) remain unclear. We sought to characterize sex differences in a large HCM referral centre population. Three thousand six hundred and seventy-three adult patients with HCM underwent evaluation between January 1975 and September 2012 with 1661 (45.2%) female. Kaplan-Meier survival curves were assessed via log-rank test. Cox proportional hazard regression analyses evaluated the relation of sex with survival. At index visit, women were older (59 ± 16 vs. 52 ± 15 years, P

Abstract Objectives This study sought to discover the key determinants of exercise capacity, maximal oxygen consumption (oxygen uptake [V o 2]), and ventilatory efficiency (ventilation/carbon dioxide output [VE/ Vco 2 ] slope) and assess the prognostic potential of metabolic exercise testing in hypertrophic cardiomyopathy (HCM). Background The intrinsic mechanisms leading to reduced functional tolerance in HCM are unclear. Methods The study sample included 156 HCM patients consecutively enrolled...

Aims We decided to determine the long-term survival of patients after alcohol septal ablation (ASA) for hypertrophic obstructive cardiomyopathy (HOCM) and compare this with the general population. Methods and results A total of 178 highly symptomatic, consecutive patients (58 ± 12 years, 53% women) were treated by ASA between April 1998 and April 2013 and followed-up for 4.8 years (IQR 2.1–7.5). At baseline, 155 patients (87%) suffered from dyspnoea ≥3 class of NYHA; at the most recent examinati...

Aims Characterization of pulmonary hypertension (PH) and the effects of myectomy in hypertrophic cardiomyopathy (HCM) remain poorly defined. The aim of the study was to investigate the effect of myectomy on PH in HCM. Methods and results This is a retrospective analysis of 306 consecutive symptomatic HCM patients (70% NYHA class III–IV) with evaluation of echocardiographic right ventricular systolic pressure (RVSP) both preceding (median 3 days) and following (median 4 days) myectomy. Compared w...

Objectives This study sought to examine sex-specific differences in outcomes after surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR) in high-risk patients with severe aortic stenosis. Background The PARTNER (Placement of Aortic Transcatheter Valve) trial demonstrated similar 2-year survival with SAVR or TAVR for high-risk patients, but sex-specific outcomes are unknown. Methods In all, 699 patients (300 female) were randomly assigned 1:1 to either SAVR or ...

Objective Reduction of left ventricular outflow tract obstruction (LVOTO) often improves symptoms in hypertrophic cardiomyopathy (HCM), but the correlation between exercise performance and measured LVOT gradients is weak. We investigated the relationship between LVOTO and cardiorespiratory responses during exercise. Methods The study cohort included 70 patients with HCM (32 with LVOTO, 55 male, age 47±13) attending a dedicated cardiomyopathy clinic and 28 normal volunteers. All underwent cardiop...

Background—There were considerable discrepancies with regard to sex-related differences in complications and prognosis after transcatheter aortic valve implantation. Methods and Results—The Cochrane library and PubMed online databases were searched. Articles reporting sex-specific post–transcatheter aortic valve implantation complications and mortality were identified. Two authors selected studies and extracted data independently. Random- and fixed-effects models were used depending on between-s...

Abstract Heart failure due to nonischemic dilated cardiomyopathy (DCM) contributes significantly to the global burden of cardiovascular disease. Myocarditis is, in turn, a major cause of acute DCM in both men and women. However, recent clinical and experimental evidence suggests that the pathogenesis and prognosis of DCM differ between the sexes. This seminar provides a contemporary perspective on the immune mediators of myocarditis, including interdependent elements of the innate and adaptive i...

Preparticipation screening of athletes with 12-lead electrocardiography has been promoted for the detection of asymptomatic cardiovascular disease, particularly hypertrophic cardiomyopathy (HC). Although false-positive electrocardiographic (ECG) results for HC are well recognized in athlete screening, expected false-negative rates are unknown. The aim of this study was to characterize the rate of false-negative ECG findings in a cohort of young asymptomatic patients with phenotypically expressed...

Hypertrophic cardiomyopathy (HCM) is a common inherited heart disease with an estimated prevalence of up to 1 in 200 individuals. In the majority of cases, HCM is considered a Mendelian disease, with mainly autosomal dominant inheritance. Most pathogenic variants are usually detected in genes for sarcomeric proteins. Nowadays, the genetic basis of HCM is believed to be rather complex. Thousands of mutations in more than 60 genes have been described in association with HCM. Nevertheless, screenin...

Accumulating evidence suggests that individuals with sarcomeric hypertrophic cardiomyopathy (HCM) carrying MYH7 mutations may have a worse prognosis than MYBPC3 mutation carriers. Myocardial deformation analysis is superior to standard echocardiography in detecting subtle myocardial dysfunction and scar formation, but studies evaluating the association with HCM genotype are scarce. We therefore aimed to compare myocardial strain parameters between MYBPC3 and MYH7 mutation carriers with proven HC...

We explore the sex-specific interaction of genetics and the environment on the clinical course and outcomes of hypertrophic cardiomyopathy (HCM). Women account for approximately one-third of patients in specialist HCM centres and reported in observational studies. As a result, evidence informing clinical guideline recommendations is based predominantly on risk factors and outcomes seen in men. However, disease progression appears to be different between the sexes. Women present at a more advance...

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is a genetic disease of the myocardium that is characterized by phenotypic variability among patients. miR-146a is a small non-coding RNA that is well known for its role in inflammation and myocardial hypertrophy. The aim of this study is to evaluate the role of miR-146a as a candidate genetic factor influencing HCM phenotype. METHODS: In this study, 140 HCM patients and 112 control individuals were genotyped for the rs2910164 single nucleotide polym...

Background null Variants in the cardiac myosin-binding protein C gene (MYBPC3) are a common cause of hypertrophic cardiomyopathy (HCM) in adults and have been associated with late-onset disease, but there are limited data on their role in paediatric-onset HCM. The objective of this study was to describe natural history and clinical outcomes in a large cohort of children with HCM and pathogenic/likely pathogenic (P/LP) MYBPC3 variants. null Methods and results null Longitudinal data from 62 conse...

AIM To compare risk algorithms (HCMRisk-Kids, ECG Risk-score) in hypertrophic cardiomyopathy (HCM) without syndrome association (ns-HCM) and with Noonan-like syndromes (RAS-HCM). METHODS A national paediatric HCM cohort (n = 151), presenting <19 years of age, mean follow-up 13.3 years, from all Swedish centres of Paediatric Cardiology (presenting 1972-2015), with 41 RAS-HCM patients (61% males), and 110 ns-HCM patients (68% familial; 65% males). The end-point was a composite of sudden cardiac de...
