Blood pressure variability activates cardiac mineralocorticoid receptor and induces cardiac remodeling in hypertensive rats.
BACKGROUND Hypertensive patients with large blood pressure variability (BPV) have aggravated target organ damage. Because the aldosterone/mineralocorticoid receptor (MR) system is a possible mechanism of hypertensive organ damage, we investigated in spontaneously hypertensive rats (SHRs) whether a specific MR blocker, eplerenone, would prevent BPV-induced aggravation of hypertensive cardiac re...
متن کاملRespective role of humoral factors and blood pressure in cardiac remodeling of DOCA hypertensive rats
Objectives: Recent studies have shown that beside elevated arterial blood pressure, humoral factors such as angiotensin II, aldosterone. endothelin or bradykinin might play a role in the cardiac hypertrophy and fibrosis secondary to hypertension. In addition, it seems that perivascular fibrosis and interstitial fibrosis are controlled by independent mechanisms. Therefore, the goal of our study ...
متن کاملSmad3 mediates cardiac inflammation and fibrosis in angiotensin II-induced hypertensive cardiac remodeling.
Although Smad3 is a key mediator of fibrosis, the functional role of Smad3 in hypertensive cardiovascular disease remains unclear. The present study tested the hypothesis that angiotensin II may activate the transforming growth factor-beta/Smad3 pathway to mediate hypertensive cardiac remodeling in Smad3 knockout (KO) and wild-type mice by subcutaneous angiotensin II infusion and in the primary...
متن کاملExaggerated blood pressure variability superimposed on hypertension aggravates cardiac remodeling in rats via angiotensin II system-mediated chronic inflammation.
Hypertensive patients with large blood pressure variability (BPV) have aggravated end-organ damage. However, the pathogenesis remains unknown. We investigated whether exaggerated BPV aggravates hypertensive cardiac remodeling and function by activating inflammation and angiotensin II-mediated mechanisms. A model of exaggerated BPV superimposed on chronic hypertension was created by performing b...
متن کاملRole of nisoldipine on blood pressure, cardiac hypertrophy, and atrial natriuretic peptides in spontaneously hypertensive rats.
The effect of long-term treatment with the calcium antagonist nisoldipine on development of hypertension, cardiac hypertrophy, and plasma levels of atrial natriuretic peptides (ANP) was determined in spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY) of the same age. Measurement of immunoreactive ANP in plasma provided a sensitive marker for the severity of hypertension and the a...
