BACKGROUND Bone marrow-derived mesenchymal stem cells (MSCs) are of great therapeutic potential after myocardial ischemic injury. However, little is known about the biological characteristics of MSCs in patients with coronary artery disease and their effects on infracted myocardium. The present study evaluated the biological characteristics of MSCs from(More)
Alcohol septal ablation (ASA) has been shown to improve left ventricular (LV) diastolic function in patients with obstructive hypertrophic cardiomyopathy (HCM). However, its beneficial effect on diastolic function assessed by cardiac magnetic resonance (CMR) has not been reported. We investigated the mid-term changes of diastolic function by CMR combined(More)
BACKGROUND Previous studies on the association between the distribution of left ventricle hypertrophy and the clinical features of hypertrophic cardiomyopathy (HCM) have yielded unclear results. The aim of this study was to investigate the differences in the prevalence, clinical features, management strategies, and long-term outcomes between patients with(More)
OBJECTIVE To determine the clinical application of pulsed Doppler tissue imaging in assessing the left ventricular diastolic function and in discriminating between normal subjects and patients with hypertrophic cardiomyopathy with various stages of diastolic dysfunction. METHODS We measured the peak diastolic velocities of mitral annulus in 81 patients(More)

OBJECTIVE To compare left ventricular outflow tract (LVOT) gradient induced by dobutamine stress echocardiography (DSE) and exercise echocardiography (EE) in patients with hypertrophic cardiomyopathy (HCM). METHODS DSE and EE were performed in 40 consecutive patients with HCM and LVOT gradient < 50 mm Hg (1 mm Hg = 0.133 kPa) at rest. Dobutamine was(More)
BACKGROUND There has been limited data addressing outcomes of extensive septal myectomy in Chinese patients with hypertrophic obstructive cardiomyopathy (HOCM). In this study, the objective was to evaluate the clinical and echocardiographic outcomes of extensive septal myectomy in a relative large number of Chinese HOCM patients over long-term follow-up.
