BACKGROUND The prognostic significance of syncope has not been investigated systematically in hypertrophic cardiomyopathy, and treatment strategies have been based largely on intuition and experience. METHODS AND RESULTS We assessed the relationship between syncope and sudden death in 1511 consecutive patients with hypertrophic cardiomyopathy. Unexplained (n=153) or neurally mediated (n=52) s...
BACKGROUND Exercise testing is performed in patients with hypertrophic cardiomyopathy to evaluate blood pressure response, a risk factor for sudden cardiac death. The prognostic role of exercise gas exchange variables is unknown. METHODS AND RESULTS Between 1998 and 2010, 1898 patients (age 47±15 years, range 16-86 years; 67% male) with hypertrophic cardiomyopathy underwent cardiopulmonary ex...
background: muscle fibers overlying the intramyocardial segment of an epicardial coronary artery are termed myocardial bridge (mb). the aim of this study was to analyze the mid-term outcome of mb and to examine its possible association with angiographic findings and concomitant cardiac pathologies such as hypertrophic cardiomyopathy (hcm). methods: from a total of 3218 patients admitted for c...
OBJECTIVES This study evaluates the clinical course and identifies risk factors for sudden cardiac death (SCD) and clinical deterioration in hypertrophic cardiomyopathy (HCM) in a large community-based population. Comparison was made with data from six tertiary referral and six nonreferral institutions. BACKGROUND Hypertrophic cardiomyopathy is a disease with marked heterogeneity in clinical ...
Introduction: Hypertrophic cardiomyopathy (HCM) is the most common genetic heart disease and the leading cause of sudden death in the young [1]. HCM is well known to contain major changes at the structural level with myocytes disarray, increase in collagen content and modification of the extracellular matrix (ECM), that can only be determined using invasive focal myocardial biopsy or after deat...
Background—The clinical efficacy of alcohol septal ablation for drug-refractory hypertrophic cardiomyopathy remains unclear. This study examines the outcome of alcohol septal ablation performed at a tertiary hypertrophic cardiomyopathy referral center. Methods and Results—Among 601 patients with severely symptomatic obstructive hypertrophic cardiomyopathy referred for alcohol septal ablation or...
BACKGROUND The impact of alcohol septal ablation (ASA)-induced scar is not known. This study sought to examine the long-term outcome of ASA among patients with obstructive hypertrophic cardiomyopathy. METHODS AND RESULTS Ninety-one consecutive patients (aged 54+/-15 years) with obstructive hypertrophic cardiomyopathy underwent ASA. Primary study end point was a composite of cardiac death and ...
