Left ventricular diastolic function assessed with cardiovascular magnetic resonance imaging and exercise capacity in patients with non-obstructive hypertrophic cardiomyopathy.
BACKGROUND In patients with non-obstructive hypertrophic cardiomyopathy (HCM) and preserved left ventricular (LV) systolic function, diastolic dysfunction is one of the major factors contributing to limited exercise capacity. Cardiovascular magnetic resonance (CMR) imaging has become a useful tool in diagnosis, risk stratification and treatment monitoring in patients with HCM. AIM To assess t...
متن کاملLeft ventricular diastolic function assessed using Doppler tissue imaging in patients with hypertrophic cardiomyopathy: relation to symptoms and exercise capacity.
BACKGROUND Conventional Doppler indices of left ventricular diastolic function do not correlate with symptoms or exercise capacity in patients with hypertrophic cardiomyopathy, because of their dependence on loading conditions. Diastolic mitral annular velocity measured using Doppler tissue imaging has been reported to be a preload independent index of left ventricular diastolic function. OBJ...
متن کاملLeft ventricular outflow tract gradient decrease with non-surgical myocardial reduction improves exercise capacity in patients with hypertrophic obstructive cardiomyopathy.
OBJECTIVES This study was undertaken to evaluate mid-term clinical results of non-surgical myocardial reduction in patients with hypertrophic obstructive cardiomyopathy. METHODS Twenty-five patients with left ventricular outflow tract obstruction (mean gradient of 84. 54+/-31.38 mmHg) and symptoms of dyspnoea, angina and/or syncope were treated with non-surgical myocardial reduction. The pati...
متن کاملLeft ventricular systolic dysfunction during exercise and dobutamine stress in patients with hypertrophic cardiomyopathy.
OBJECTIVES We sought to characterize stress-induced left ventricular systolic dysfunction in patients with hypertrophic cardiomyopathy (HCM). BACKGROUND Myocardial ischemia and diastolic dysfunction occur in patients with HCM. We hypothesized that, in the setting of transient myocardial ischemia, left ventricular systolic dysfunction occurs during exercise and dobutamine stress. METHODS We ...
متن کاملProgressive left ventricular remodeling in patients with hypertrophic cardiomyopathy and severe left ventricular hypertrophy.
OBJECTIVES The aim of this study was to determine the natural history of patients with hypertrophic cardiomyopathy (HCM) and severe left ventricular hypertrophy (LVH) (i.e., maximal left ventricular wall thickness [MLVWT] >/=30 mm) and whether changes in cardiac morphology influence the course of the disease. BACKGROUND Severe LVH is common in young and rare among elderly patients with HCM. T...
