Angiotensin-converting enzyme activity was measured in lumbar cerebrospinal fluid from patients with 'probable' Alzheimer's disease (n = 17) and age-matched controls (n = 19), using a spectrofluorimetric method. In contrast to a previous finding, no statistically significant difference in the mean (specific) angiotensin-converting enzyme activity was found between the two groups. No correlation...

Background: Therapeutic interchange is widely used in geriatric settings, such as angiotensin enzyme converting inhibitors and angiotensin II receptor antagonists and angiotensin receptor blockers (sartans). Objective: we evaluate the clinical impact (efficacy and tolerance) of a therapeutic interchange program for noncomplicated hypertension. Method: 13 patients receiving angiotensin enzyme co...

Angiotensin-Converting Enzyme Inhibitors (ACEI) are commonly used to prevent cardiac remodeling in patients with ST-Segment Elevation Myocardial Infarction (STEMI).

It is well recognized that the renin-angiotensin system plays an important role in the regulation of arterial pressure and sodium homeostasis. Recent years, many studies have shown that local tissue angiotensin II levels are differentially regulated and cannot be explained on the basis of circulating concentrations. All of the components needed for angiotensin II generation are present within t...

Angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers have different pharmacologic mechanisms for blocking the effect of the renin-angiotensin-aldosterone system on the cardiovascular system. Pharmacologically, the combination of these drug classes completely blocks the deleterious effect of angiotensin in patients with heart failure. However, clinical trials have not shown...

analysis: effect of monotherapy and combination therapy with inhibitors of the renin angiotensin system on proteinuria in renal disease. A, Morita H et al. Combination treatment of angiotensin-II receptor blocker and angiotensin-converting-enzyme inhibitor in non-diabetic renal disease (COOPERATE): a randomised controlled trial. Coleman CI et al.
