[Central and renal hemodynamic indices under physical load in hypertension]. 1978

A B Rapoport, and T A Evdokimova

The article shows the results of studying the functional condition of the cardiovascular system in hypertensive disease. Under physical load healthy individuals demonstrated an increase in arterial pressure, rate of cardiac contractions, cardiac and stroke output, arteriovenous difference in oxygen, and diminution in the circulation volume, total peripheral resistance, renal blood flow and renal fraction of the minute blood volume. In patients with hypertensive disease there was a tendency to a lesser decrease in the cardiac output under load, the difference with the indices of healthy individuals increased with each stage of the disease. In hypertensive disease of stage IIB there were significantly smaller cardiac output, diminution of stroke volume under load, and a sharper rise than in the control group of arteriovenous difference in oxygen. The diminution of renal blood flow in response to the load was more marked in hypertensive disease.

UI	MeSH Term	Description	Entries
D006973	Hypertension	Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D002302	Cardiac Output	The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).	Cardiac Outputs,Output, Cardiac,Outputs, Cardiac
D003971	Diastole	Post-systolic relaxation of the HEART, especially the HEART VENTRICLES.	Diastoles
D005082	Physical Exertion	Expenditure of energy during PHYSICAL ACTIVITY. Intensity of exertion may be measured by rate of OXYGEN CONSUMPTION; HEAT produced, or HEART RATE. Perceived exertion, a psychological measure of exertion, is included.	Physical Effort,Effort, Physical,Efforts, Physical,Exertion, Physical,Exertions, Physical,Physical Efforts,Physical Exertions
