Background: The role of Renin Angiotensin System (RAS) in ischemic/reperfusion (I/R) injuries is not fully elucidated. Furthermore, it is not clear whether inhibition of RAS by Angiotensin-Converting Enzyme (ACE) inhibitors has beneficial effects in terms of protecting the brain from I/R injuries. In this study enalapril is used as an ACE inhibitor to evaluate the role of RAS in I/R injuries in...

Objective—To examine the eVect of concomitant intake of â blockers with angiotensin converting enzyme (ACE) inhibitors, diuretics, or both on plasma renin concentrations in a population based sample (MONICA survey, Augsburg, Germany). Subject and methods—728 individuals were studied, of whom 171 were treated using monotherapy (ACE inhibitor (n = 21), diuretic (n = 10), or â blocker (n = 72)), o...

PURPOSE We investigated the effect of angiotensin-converting enzyme (ACE)- inhibitor, statin, and beta-blocker usage before coronary bypass surgery (CABG) on vascular reactivity of the internal mammary artery (IMA). METHODS Patients, who underwent elective CABG were evaluated. Samples of IMA obtained from 22 patients were divided into 4 groups in respect of drugs used by patients before bypas...

BACKGROUND Angiotensin-converting enzyme (ACE) inhibitors are valuable agents for the treatment of hypertension, heart failure, and other cardiovascular and renal diseases. The cardioprotective effects of ACE inhibitors are mediated by blockade of both conversion of angiotensin (Ang) I to Ang II and kinin hydrolysis. Here, we report a novel mechanism that may explain the cardiac antifibrotic ef...

A new series of alkylthio imidazole analogues of captopril, an ACE inhibitor used in the treatment of hypertension, was designed and synthesized in order to obtain agents more active than captopril with less side effects. All the compounds thus prepared were purified and characterized by IR, NMR and Mass analytical instruments.

BACKGROUND A dry, persistent cough is a well-described class effect of the angiotensin-converting enzyme (ACE) inhibitor medications. The mechanism of ACE inhibitor-induced cough remains unresolved, but likely involves the protussive mediators bradykinin and substance P, agents that are degraded by ACE and therefore accumulate in the upper respiratory tract or lung when the enzyme is inhibited,...

BACKGROUND AND OBJECTIVE Because high-dose angiotensin-converting enzyme (ACE) inhibitor therapy is desirable in patients with chronic heart failure (CHF), we sought to determine the usage and dosing patterns of ACE inhibitors in CHF patients at a governmental hospital in Palestine. METHODS This cross-sectional study was conducted between September 2006 and August 2007. All patients admitted ...

Background The absolute risk of angiotensin-converting enzyme (ACE) inhibitor angioedema is 0.3% [1]. The mechanism is felt to be accumulation of bradykinin. The current treatment is discontinuation of ACE-I inhibitor, and intubation if necessary. Icatibant is a bradykinin receptor antagonist, useful in treating hereditary angioedema [2]. We present a patient from a Canadian center who had ACE-...
