Mineralocorticoid receptor blockade improves mortality early after myocardial infarction (MI). This study investigated the vascular effects of mineralocorticoid receptor blockade in the early phase postinfarction in rats. Starting immediately after coronary ligation, male Wistar rats were treated with placebo or eplerenone (100 mg/kg/d). After 7 days, hemodynamic assessment was performed and en...
Cardiac aldosterone levels have not been evaluated in diastolic heart failure (DHF), and its roles in this type of heart failure remain unclear. This study aimed to detect cardiac aldosterone by use of a liquid chromatographic-mass spectrometric method and to assess the effects of mineralocorticoid receptor blockade on hypertensive DHF. Dahl salt-sensitive rats fed 8% NaCl diet from 7 wk (hyper...
Overnutrition and insulin resistance are especially prominent risk factors for the development of cardiac diastolic dysfunction in females. We recently reported that consumption of a Western diet (WD) containing excess fat (46%), sucrose (17.5%), and high fructose corn syrup (17.5%) for 16 weeks resulted in cardiac diastolic dysfunction and aortic stiffening in young female mice and that these ...
Circulating angiotensin II (Ang II) activates a central aldosterone-mineralocorticoid receptor neuromodulatory pathway, which mediates most of the Ang II-induced hypertension. This study examined whether specific central infusion of Ang II also activates this central aldosterone-mineralocorticoid receptor pathway. Intracerebroventricular infusion of Ang II at 1.0, 2.5, and 12.5 ng/min for 2 wee...
The effect of aldosterone on connective tissue growth factor (CTGF) was examined in rat embryonic ventricular myocytes. Upon aldosterone treatment, CTGF expression was significantly increased in a dose and time-dependent manner. To explore the molecular mechanism for this upregulation, we examined the role of mineralocorticoid receptor. Pre-treatment of an antagonist (spironolactone) at 5-fold ...
Intravenous mineralocorticoid receptor antagonists (MRAs) have been used in some centers for decades to reduce the risk of hypokalemia and boost diuresis acutely decompensated heart failure (ADHF). We report well-tolerated use intravenous MRAs as a rescue procedure 3 patients admitted ADHF with important diuretic resistance. Undertaking trials evaluating effect this therapeutic strategy could r...
