The renin-angiotensin-aldosterone system and catecholamines in chronic congestive heart failure. Effect of angiotensin I converting enzyme inhibitor SQ 14225 (captopril).

P23: The Effects of Captopril, as Angiotensin Converting Enzyme Inhibitor, on LPS-Induced Systemic Inflammation

It has been shown that the renin-angiotensin system (RAS) plays key roles in the inflammation process. Imbalance in the oxidant-antioxidant system is one of the major causes of inflammation. In the present study, the effects of captopril on total and differential WBC, oxidative stress in systemic inflammation produced by lipopolysaccharide (LPS) were investigated. The rats were divided to: cont...

New Perspectives in the Renin-Angiotensin-Aldosterone System (RAAS) I: Endogenous Angiotensin Converting Enzyme (ACE) Inhibition

Angiotensin-converting enzyme (ACE) inhibitors represent the fifth most often prescribed drugs. ACE inhibitors decrease 5-year mortality by approximately one-fifth in cardiovascular patients. Surprisingly, there are reports dating back to 1979 suggesting the existence of endogenous ACE inhibitors, which endogenous inhibitory effects are much less characterized than that for the clinically admin...

The effect of progressive aerobic continuous training on angiotensin-1, angiotensin-2 and angiotensin-converting enzyme type 2 in patients with heart failure

Background: Chronic hypertension causes structural and functional changes in the heart, ultimately leading to heart failure (HF), which further increases mortality and morbidit. HF is a complex clinical syndrome caused by various structural or functional abnormalities of the heart that impair the filling capacity of the ventricles. The findings of various trials have shown the association betwe...

Angiotensin converting enzyme inhibition in patients with congestive heart failure.

The etiology of afterload elevation in congestive cardiac failure is unclear, but experimental evidence suggests a role for the renin-angiotensin system in maintaining elevated peripheral vascular resistance. The angiotensin converting enzyme inhibitor SQ20,881 was administered to eight patients with congestive cardiac failure (four hypertensives, four normotensives) during or one day after dia...
