Left ventricular mass (LVM) is a highly heritable trait and an independent risk factor for all-cause mortality. So far, genome-wide association studies have not identified the genetic factors that underlie LVM variation, and the regulatory mechanisms for blood-pressure-independent cardiac hypertrophy remain poorly understood. Unbiased systems genetics(More)
INTRODUCTION Idiopathic dilated cardiomyopathy (DCM) is a leading cause of heart failure characterized by an enlarged ventricular cavity leading to systolic dysfunction. DCM patients have a considerable annual mortality rate of 5–10%, with half of them being sudden unexpected deaths due to ventricular tachycardia (VT) or ventricular fibrillation (VF). 1(More)
BACKGROUND Potential cardiac donors show various degrees of myocardial dysfunction, and the most severely affected hearts are unsuitable for transplantation. The cause of this acute heart failure is poorly understood. We investigated whether alterations in calcium-handling proteins, beta-adrenoceptor density, or the inhibitory G protein Gialpha could(More)
