Effects of chronic heart failure on the responsiveness to angiotensin I and to angiotensin converting enzyme inhibition with cilazapril in rats.

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...

Effect of chronic angiotensin converting enzyme inhibition on angiotensin I and bradykinin metabolism in rats.

We determined the effect of chronic administration of the angiotensin converting enzyme (ACE) inhibitor, enalapril, on the in vivo pulmonary inactivation of bradykinin (BK) and conversion of angiotensin I (Ang I). In addition we assessed whether chronic ACE inhibition influenced the activity of prolylendopeptidase (PEP), which metabolizes Ang I to generate angiotensin-(1-7) (Ang-[1-7]) and inac...

Effects of Chronic Angiotensin Converting Enzyme Inhibition

Background. Previous studies have shown that global left ventricular function is depressed after myocardial infarction. However, little is known about the effects of myocardial infarction on contractility and the passive-elastic properties of residual myocardium. Methods and Results. We evaluated isometric function and passive myocardial stiffness in isolated, noninfarcted left ventricular papi...

Angiotensin Converting Enzyme in Sarcoidosis

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...
