Lecture 22: Control of Blood Pressure
Blood flows only when its pressure is higher at one place than in another, and it flows always from the place of higher pressure towards the place of...

Histamine H2-receptor antagonism improves conduit artery endothelial function and reduces plasma aldosterone level without lowering arterial blood pressure in angiotensin II–hypertensive mice
Aldosterone through the mineralocorticoid receptor MR has detrimental effects on cardiovascular disease. It reduces the bioavailability of nitric...

Influence of a Decrease in Blood Viscosity on Arterial Pressure in Normotensive and Spontaneously Hypertensive Rats
We investigated the effect of a decrease in blood viscosity on the mean BP during isovolumic hemodilution and vasodilating activity of the...

Association of central blood pressure with an exaggerated blood pressure response to exercise among elite athletes
PurposeThe systolic blood pressure/workload (SBP/MET) slope was recently reported to be a reliable parameter to identify an exaggerated blood...

Sex-specific genetic architecture of blood pressure
The genetic and genomic basis of sex differences in blood pressure (BP) traits remain unstudied at scale. Here, we conducted sex-stratified and...

Evaluation of Electrocardiogram Parameters and Heart Rate Variability During Blood Pressure Elevation by Phenylephrine in Cirrhotic Rats
Cirrhotic cardiomyopathy is a myocardial disease that may go undetected in the early stages due to peripheral vasodilatation. The aim of the study...

Potential considerations with estimating blood flow restriction pressure in the lower body using a narrower cuff
Blood flow restriction pressures are typically set as a percentage of the arterial occlusion pressure. For those who do not have the ability to...
