background: there is controversy over the potential benefits/harms of the usage of angiotensin-converting enzyme inhibitors (aceis) or angiotensin receptor blockers (arbs) as regards the postoperative mortality of coronary artery bypass grafting (cabg). this study investigates the correlation between the in-hospital mortality of cabg and the preoperative administration of acei/arb. methods: out...
there are controversial reports about the effect of captopril on pain modulation. also while captopril may potentiate morphine analgesia, enalapril has not such an effect and interaction of morphine with angiotensin ii receptor antagonists and other angiotensin converting enzyme inhibitors has not been studied yet. therefore, this study was designed to assess the effect of captopril, lisinopril...
We tested the hypotheses that angiotensin-converting enzyme insertion/deletion (I/D) and angiotensinogen 235 methionine/threonine (M/T) substitution gene polymorphisms influence angiotensin-converting enzyme and angiotensiongen serum concentrations and cardiac dimensions in 91 monozygotic and 41 dizygotic twin pairs. Cardiac dimensions were determined echocardiographically. Angiotensin-converti...
BACKGROUND The effect on cardiovascular outcomes of withholding angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers in chronic users before noncardiac surgery is unknown. METHODS In this international prospective cohort study, the authors analyzed data from 14,687 patients (including 4,802 angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker users) ...
Angioedema is a potentially life-threatening adverse effect of angiotensin-converting enzyme inhibitors. Bradykinin and substance P, substrates of angiotensin-converting enzyme, increase vascular permeability and cause tissue edema in animals. Studies indicate that amino-terminal degradation of these peptides, by aminopeptidase P and dipeptidyl peptidase IV, may be impaired in individuals with ...
Angiotensin converting enzyme was assayed in serum free culture supernatants from unstimulated rheumatoid nodule cells. Angiotensin converting enzyme was released spontaneously and the angiotensin converting enzyme derived from rheumatoid nodule cells was suppressed in a dose and time dependent manner by the protein synthesis inhibitor cycloheximide. These data suggest the constitutive de novo ...
The reaction of the renin-angiotensin system to acute angiotensin converting enzyme inhibition was investigated in a single-blind, crossover study in nine normal volunteers receiving two out of three regimens in random order: the new converting enzyme inhibitor benazepril (20 mg once or 5 mg four times at 6-hour intervals) or enalapril (20 mg). Plasma converting enzyme activity, drug levels, an...
background and aims: diabetic nephropathy (dn) is the most common cause of end-stage renal failure which could increase the risk of cardiovascular disease and morbidity and mortality in patients. the aim of this study was to investigate new modalities for treatment of diabetic nephropathy. methods:this study was a mini-review research to investigate drugs that are used for dn treatment. results...
Changes in tissues and general renin-angiotensin system’s function are the most important factors in cardiovascular disease such as essential hypertension. Recent research shows that general renin - angiotensin system affects the short and immediate response , and that of the...
Background: Angiotensin converting enzyme (ACE) upregulation in stromal cells of joints affected by rheumatoid arthritis may lead to higher tissue angiotensin II that is a vasoconstrictor and mitogen factor. To date, the role of angiotensin II on regulating blood flow in inflamed joints has not been studied. Methods: Acute and chronic joint inflammation was induced in rabbits by intra-articular...
