Manipulating angiotensin metabolism with angiotensin converting enzyme 2 (ACE2) in heart failure

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...

Serum Angiotensin Converting Enzyme in Patients with Psoriasis

Background: Controversial data concerning the elevation of serum angiotensin-converting enzyme in psoriasis are reported in the literature. In order to verify whether this abnormality exists in Iranian patients, we performed this study. Method: Serum angiotensin-converting enzyme level was measured in 40 psoriatics. According to clinical forms of psoriasis, patients were further divided into th...

Evaluation of angiotensin-converting enzyme (ACE), its homologue ACE2 and neprilysin in angiotensin peptide metabolism.

In the RAS (renin-angiotensin system), Ang I (angiotensin I) is cleaved by ACE (angiotensin-converting enzyme) to form Ang II (angiotensin II), which has effects on blood pressure, fluid and electrolyte homoeostasis. We have examined the kinetics of angiotensin peptide cleavage by full-length human ACE, the separate N- and C-domains of ACE, the homologue of ACE, ACE2, and NEP (neprilysin). The ...

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...
