Abstract

Many factors have been reported to stimulate the release of brain natriuretic peptide (BNP) as well as atrial natriuretic peptide (ANP). In hypertensive patients, however, little is known about whether these factors differ from those in normotensive subjects or if they are influenced by antihypertensive treatment. We measured the plasma concentrations of BNP and ANP in 12 hypertensive patients and examined the chronic effects of beta-adrenoceptor blockade on BNP secretion during exercise with a bicycle ergometer. The exercise raised both plasma BNP and ANP with concomitant increases in systolic blood pressure, heart rate (HR) and plasma norepinephrine (NE) and epinephrine (Epi) before and after treatment. Before treatment, the changes in ANP and BNP correlated with that in HR (p < 0.05). After treatment 4 wk of treatment, the change in ANP correlated with those in NE and Epi as well as HR. Multivariate regression analysis indicated that only NE was a significant stimulus for ANP secretion during the treatment period. As for BNP, HR was the only significant stimulant for its secretion both before and after treatment. In essential hypertension, beta-adrenergic receptor blockade affected the factors stimulating exercise-induced AN...Continue Reading

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
