Effects of verapamil on left ventricular systolic function and diastolic filling in patients with hypertrophic cardiomyopathy.
Verapamil improves exercise capacity in patients with hypertrophic cardiomyopathy (HCM), but its mechanism of action are unknown. We examined the effects of oral verapamil (320-480 mg/day) on resting left ventricular (LV) systolic and diastolic function in patients with HCM. High-temporal-resolution time-activity curves from gated technetium-99m radionuclide angiograms were analyzed before and ...
متن کاملEffects of alterations in systolic pressure on radionuclide measurements of left ventricular filling dynamics.
To determine the effects of steady-state left ventricular systolic pressure alterations on radionuclide measures of left ventricular filling dynamics, we studied 15 normal patients and 17 patients with nonischemic heart disease. Micromanometer left ventricular pressures and computer assisted forward gated radionuclide angiograms were acquired simultaneously. Right atrial pacing maintained heart...
متن کاملLeft ventricular diastolic filling and systolic function of young and older trained and untrained men.
Aging is associated with impaired early diastolic filling; however, the effect of endurance training on resting diastolic function in older subjects is unclear. Heart rate and ventricular loading conditions affect mitral inflow velocities measured by Doppler echocardiography; therefore, tissue Doppler imaging of mitral annular velocity, which is relatively preload independent, was combined with...
متن کاملLeft ventricular systolic function and diastolic filling after intermittent high intensity team sports.
BACKGROUND Prolonged steady state exercise can lead to a decrease in left ventricular (LV) function as well as promote the release of cardiac troponin T (cTnT). There is limited information on the effect of intermittent high intensity exercise of moderate duration. OBJECTIVES To determine the effect of intermittent high intensity exercise of moderate duration on LV function. METHODS Ninetee...
متن کاملFilling invariants of systolic complexes and groups
Systolic complexes were introduced in Januszkiewicz–Świa̧tkowski [12] and, independently, in Haglund [10]. They are simply connected simplicial complexes satisfying a certain condition that we call simplicial nonpositive curvature (abbreviated SNPC). The condition is local and purely combinatorial. It neither implies nor is implied by nonpositive curvature for geodesic metrics on complexes, but ...
