Managing resistant hypertension: focus on mineralocorticoid-receptor antagonists
Mineralocorticoid-receptor antagonists (MRAs) have proven to be effective in some types of hypertension, especially in resistant hypertension (RHTN). In this phenotype of hypertension, the renin-angiotensin-aldosterone pathway plays an important role, with MRAs being especially effective in reducing blood pressure. In this review, we show the relevance of aldosterone in RHTN, as well as some cl...
متن کاملA focus on paediatric hypertension
Invited editorial " The cardiovascular benefits of reduced salt intake are on par with the benefits of population-wide reductions in tobacco use, obesity, and cholesterol levels. A regulatory intervention designed to achieve a reduction in salt intake of 3 g per day (...) would be more cost-effective than using medications to lower blood pressure in all persons with hypertension. " Kirsten Bibb...
متن کاملHaemodynamic unloading reverses occlusive vascular lesions in severe pulmonary hypertension.
AIMS An important pathogenic mechanism in the development of idiopathic pulmonary arterial hypertension is hypothesized to be a cancer-like cellular proliferation independent of haemodynamics. However, because the vascular lesions are inseparably coupled with haemodynamic stress, the fate of the lesions is unknown when haemodynamic stress is eliminated. METHODS AND RESULTS We applied left pul...
متن کاملVascular responsiveness in rats resistant to aldosterone-salt hypertension.
Wistar-Furth rats have been shown to be resistant to mineralocorticoid-salt hypertension, but the mechanism for this resistance is unknown. In the current experiments, adult male Wistar and Wistar-Furth rats were given a subcutaneous aldosterone infusion (0.15 microgram/hr) for 4 weeks, and changes in blood pressure and vascular reactivity were studied. Rats received a 1% NaCl, 0.2% KCl solutio...
متن کاملReactive oxygen species, vascular Noxs, and hypertension: focus on translational and clinical research.
SIGNIFICANCE Reactive oxygen species (ROS) are signaling molecules that are important in physiological processes, including host defense, aging, and cellular homeostasis. Increased ROS bioavailability and altered redox signaling (oxidative stress) have been implicated in the onset and/or progression of chronic diseases, including hypertension. RECENT ADVANCES Although oxidative stress may not...
