Time-varying myocardial stress and systolic pressure-stress relationship: role in myocardial-arterial coupling in hypertension.
BACKGROUND Myocardial afterload depends on left ventricular (LV) cavity size, pressure, and wall thickness, all of which change markedly throughout ejection. We assessed the relationship between instantaneous ejection-phase pressure and myocardial stress and the effect of arterial wave reflections on myocardial stress in hypertensive and normotensive adults. METHODS AND RESULTS We studied 42 ...
متن کاملAdministration of telmisartan reduced systolic blood pressure and oxidative stress
14 We investigated the effects of telmisartan, the blocker of angiotensin II receptor 1, on 15 the regulation of systolic blood pressure (SBP) and oxidative stress through 16 endothelial nitric oxide (NO) release in spontaneously hypertensive rats (SHR). SHRs 17 randomly received placebo, oral feeding of telmisartan (5 mg/kg or 10 mg/kg) every 18 day and Wistar-Kyoto rats (WKYs) served as normo...
متن کاملArterial properties as determinants of time-varying myocardial stress in humans.
Myocardial and arterial load are time-varying phenomena. Despite their importance in myocardial function, the arterial properties that determine time-resolved myocardial wall stress are unknown. We aimed to assess arterial properties as determinants of time-resolved myocardial stress among 1214 men and women enrolled in the Asklepios Study. Time-resolved central pressure, flow, and left ventric...
متن کاملEffect of orthostatic stress on systolic time intervals in rabbits.
Systolic time intervals (STI) are sensitive indices of myocardial function. The present study was conducted to evaluate the effect of orthostatic stress on STI before and after 70 degrees head up tilt (HUT) in rabbits. Electrocardiogram (ECG), phonocardiogram and carotid arterial pulse were recorded simultaneously on four channel polyrite (INCO). Within 1 second of tilt there was a significant ...
