Left ventricular regional relaxation and its nonuniformity in hypertrophic nonobstructive cardiomyopathy.
BACKGROUND Regional nonuniformity has been suggested to be closely related to left ventricular (LV) relaxation in diseased heart. The purpose of the present study was to assess LV global and regional relaxation in patients with nonobstructive hypertrophic cardiomyopathy (HCM). METHODS AND RESULTS Left ventriculography was conducted simultaneously with pressure micromanometry in 10 normal cont...
متن کاملLeft ventricular diastolic gradient in hypertrophic cardiomyopathy☆
Systolic left ventricular (LV) gradients and diastolic dysfunction are widely studied in hypertrophic cardiomyopathy (HCM) [1,2], however diastolic gradients have never been described. A patient with HCM, mid-cavity obliteration and apical aneurysm, diagnosed by both 2D echocardiography (Fig. 1, panel A) and cardiac magnetic resonance (Fig. 1, panel B), showed color Doppler aliasing effect at m...
متن کاملRegional left ventricular mechanics in hypertrophic cardiomyopathy.
BACKGROUND Nonuniformity is a determinant of diastolic function. In patients with hypertrophic cardiomyopathy, hypertrophy, abnormal calcium handling, and regional ischemia can also play a role. This study was designed to assess regional mechanics, asynchrony, and asynergy in patients with hypertrophic cardiomyopathy. METHODS AND RESULTS Nine control subjects and 22 patients with hypertrophic...
متن کاملRegional left ventricular wall movement in hypertrophic cardiomyopathy.
Left ventriculograms of 20 patients with hypertrophic cardiomyopathy were digitised frame by frame and analysed using a contour display. Abnormalities of regional wall movement were present in 17, and included an abnormal sequence of inward movement during systole (13), regional delay in the onset of inward movement (10), and an abnormal dispersion of peak velocities (5). Diastolic wall movemen...
متن کاملEffects of losartan on left ventricular hypertrophy and fibrosis in patients with nonobstructive hypertrophic cardiomyopathy.
OBJECTIVES The aim of this study was to evaluate the effects of losartan on left ventricular (LV) hypertrophy and fibrosis in patients with nonobstructive hypertrophic cardiomyopathy (HCM). BACKGROUND Despite evidence that myocardial hypertrophy and fibrosis are mediated by angiotensin II and are important determinants of morbidity and mortality in patients with HCM, no prior studies have eva...
