We previously reported that exogenous angiotensin (Ang) 1-7 has adverse cardiac effects in experimental kidney failure due to its action to increase cardiac angiotensin converting enzyme (ACE) activity. This study investigated if the addition of an ACE inhibitor (ACEi) to Ang 1-7 infusion would unmask any beneficial effects of Ang 1-7 on the heart in experimental kidney failure. Male Sprague-Dawley rats underwent subtotal nephrectomy (STNx) and were treated with vehicle, the ACEi ramipril (oral 1mg/kg/day), Ang 1-7 (subcutaneous 24 μg/kg/h) or dual therapy (all groups, n = 12)...

Angioedema is a severe form of an allergic reaction characterized by the localized edematous swelling of the dermis and subcutaneous tissues. Angiotensin-converting enzyme inhibitor-induced angioedema (ACEI-IA) is an allergic reaction that can be severe in some cases requiring advanced management measures. Fresh frozen plasma has been used off-labeled in some case reports to improve and to prevent worsening of the angioedema in a few cases of ACEI-IA. We are reporting this case to increase the awareness of physicians and to widen their therapeutic options when encountering this clinically significant condition...

Background -Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) occurs in 5-10% of all patients with MI. Clinical trials of secondary prevention treatment in MINOCA patients are lacking. Therefore, the aim of this study was to examine the associations between treatment with statins, renin-angiotensin system blockers, beta-blockers, dual antiplatelet therapy and long-term cardiovascular events. Methods -Observational study of MINOCA patients recorded in the SWEDEHEART registry between July 2003 and June 2013 and followed until December 2013 for outcome events in the Swedish Cause of Death Register and National Patient Register...

BACKGROUND: Angiogenesis is implicated in formation of gastrointestinal arteriovenous malformations (AVMs). Angiotensin II signaling is involved in angiogenesis through the vascular endothelial growth factor (VEGF) and angiopoietin-2 pathways. We hypothesized that angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) therapy would be associated with a reduced risk of all-cause gastrointestinal bleeding (GIB) and AVM-associated GIB in patients with left ventricular assist devices (LVADs)...

Blockade of the angiotensin-renin system, with angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARBs), has been shown to improve cardiac outcomes following myocardial infarction and delay progression of heart failure. Acromegaly is associated with a disease-specific cardiomyopathy, the pathogenesis of which is poorly understood.The cardiac indices of patients with active acromegaly with no hypertension (Group A, n=4), established hypertension not taking ACEi/ARBs (Group B, n=4) and established hypertension taking ACEi/ARBs (Group C, n=4) were compared using cardiac magnetic imaging...

BACKGROUND: Clopidogrel is a prodrug, the minority of which is converted to an active metabolite by hepatic cytochrome P450 (CYP2C19), however, most of it is metabolized to inactive substance by hepatic carboxylesterase1 (CES1). Meanwhile angiotensin-converting enzyme inhibitors (ACEIs) are mostly metabolized by CES1. We aimed to assess the impact of ACEIs on platelet inhibition by clopidogrel. METHODS: We genotyped variants CES1, CYP2C19*2 and *3 in 502 patients with acute coronary syndrome (ACS) receiving clopidogrel therapy, and analyzed the effects of ACEIs on responsiveness to clopidogrel by the vasodilator-stimulated phosphoprotein (VASP) phosphorylation assay and ADP-stimulated impedance whole blood platelet aggregation assay...

Add-on mineralocorticoid-receptor-antagonists (MRAs) spironolactone and eplerenone can enhance the cardioprotective action of angiotensin-converting-enzyme-inhibitors (ACEIs), angiotensin-receptor-blockers (ARBs) and/or β-blockers in non-dialysis patients with congestive heart failure (CHF) and reduced left ventricular (LV) ejection fraction. The efficacy and safety of MRAs among patients on chronic dialysis is less well studied. A growing body of evidence derived from small randomized studies suggests that MRA therapy may improve a number of surrogate cardiovascular (CV) risk factors (i...

: 213 Background: Anthracyclines and anti-Her-2 targeted therapy are commonly used effective breast cancer treatments. They are known to decrease Left Ventricular Ejection Fraction (LVEF), which may increase patients' morbidity and mortality. There is currently no consensus on post treatment cardiac follow-up. Recent observations suggested that ACEI and B blocker drugs could have cardioprotective effects. We conducted a retrospective study to assess patients' cardiac outcome using post-treatment LVEF follow-up and effect of ACEI and B blocker on cardiac outcome for breast cancer patients who received cardiotoxic agents in our institution...

The potential protective effect of renin-angiotensin system (RAS) inhibitors is a subject of increasing interest due to their possible role as chemopreventive agents against colorectal cancer (CRC). To evaluate this association, we conducted a case-control study with 2165 cases of colorectal cancer, diagnosed between 2007 and 2012, and 3912 population controls frequency matched (by age, sex and region) from the Spanish multicenter case-control study MCC-Spain. We found a significant protective effect of the angiotensin-converting enzyme Inhibitors (ACEIs) against CRC, limited to the under-65years group (OR=0...

BACKGROUND: Perioperative use of angiotensin receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEis) in patients undergoing cardiac operations remains controversial. The current practice of discontinuing renin-angiotensin-system inhibitors preoperatively may negate their beneficial effects in vulnerable populations, including patients with metabolic syndrome, who exhibit elevated renin-angiotensin system activity. We hypothesized that preoperative ARB use is associated with reduced incidence of postoperative complications, compared with ACEi or no drug, in patients with metabolic syndrome undergoing coronary artery bypass grafting...

AIM: The combination of weight excess and hypertension significantly contributes to cardiovascular risk and progressive kidney damage. An unfavorable renal hemodynamic profile is thought to contribute to this increased risk and may be ameliorated by direct renin inhibition (DRI). The aim of this trial was to assess the effect of DRI on renal and systemic hemodynamics and on RAAS activity, in men with weight excess and hypertension. METHODS: A randomized, double-blind, cross-over clinical trial to determine the effect of DRI (aliskiren 300 mg/day), with angiotensin converting enzyme inhibition (ACEi; ramipril 10 mg/day) as a positive control, on renal and systemic hemodynamics, and on RAAS activity (n = 15)...
