To assess the coronary flow velocity - pressure relationship distal to a stenosis, and to evaluate the influence of microvascular abnormalities on this relationship, coronary flow velocity and coronary pressure were measured simultaneously in 38 patients (42 vessels). The instantaneous peak coronary flow velocity was plotted against the simultaneous measured distal coronary pressure, and the sl...
In the past decade, pulse pressure has emerged as a strong predictor of cardiovascular morbidity and mortality. During aging, elevation of pulse pressure is a consequence of stiffening of the arterial wall. The relationship between pulse pressure and the renal aging process was studied in a cohort of 212 patients with never-treated isolated systolic hypertension. Glomerular filtration rate and ...
To understand more fully the role of the arterial baroreceptor reflex on systemic and pulmonary vascular resistance, we studied the influence of the carotid sinus baroreceptor reflex control system on the entire systemic and pulmonary arterial pressure-flow relationships. Ten pentobarbital-anesthetized dogs, whose carotid sinuses were isolated, were used in a preparation in which the right and ...
