Angiotensin-converting enzyme catalyzes the formation of angiotensin II (Ang II) from Ang I but also degrades bradykinin (BK). Ang II, acting through the AT1 receptor, is a potent vasoconstrictor, stimulates norepinephrine release from sympathetic nerve terminals in the heart, and causes hypertrophy of cardiac myocytes. BK, via activation of the BK2 receptor, stimulates the release of NO and pr...

Cardiovascular disease (CVD) is responsible for ∼27% of deaths worldwide, with 80% of these occuring in developing countries. Hypertension is one of the most important treatable factors in the prevention of CVD. Angiotensin-I converting enzyme (ACE) is a two-domain dipeptidylcarboxypeptidase that is a key regulator of blood pressure as a result of its critical role in the reninangiotensin- aldo...

Angiotensin-converting enzyme (ACE) inhibitors are the most common medications responsible for angioedema. Angioedema is a potentially life threatening conditions especially in geriatric age patients that they have take a several medications include ACE inhibitors and non steroidal anti inflammatory drugs. We present a case an ACE inhibitor induced angioedema that confused many clinical events.

Two types of angiotensin-converting enzyme (ACE) inhibitors, lisinopril and benazepril HCl, were tested in neuroblastoma cells found to upregulate low-density lipoprotein-receptor-related protein 1B (LRP1B) 14-3-3 zeta/delta. Additionally, HCl was increase the expression calreticulin. The upregulation these proteins by ACE inhibitors may contribute amelioration cognitive deficits Alzheimer’s di...

The enormous benefits of inhibition of ACE demonstrate that manipulation of the metabolism of peptide hormones is a valuable therapeutic strategy for cardiovascular disease. Recent attempts to expand these benefits have combined ACE inhibition with inhibition of other peptidases such as neutral endopeptidase (NEP) in a single molecule, a strategy known as vasopeptidase inhibition. NEP metaboliz...

We compared the effects of two long-term antihypertensive treatments (ACE inhibitors vs. Ca antagonists) on left ventricular hypertrophy (LVH) and LV function in patients with essential hypertension and LVH. After a washout period of at least 4 wk, ceronapril or delapril was administered to 18 patients and nifedipine or nicardipine to 15 patients for 6 months. Mean blood pressure (MBP), LV mass...

Increasing evidence implies beneficial effects of angiotensin-converting enzyme (ACE) inhibitors beyond those of their original indications to control hypertension. One of the most attractive non-hemodynamic properties of ACE inhibitors is their ability to regulate cytokine production. The mechanism(s) underlying the role of ACE inhibitors on cytokine synthesis are not well understood but they ...

BACKGROUND AND OBJECTIVES The discontinuation of drugs such as angiotensin-converting enzyme inhibitors (ACE inhibitors) has been suggested based on reports of hypotension during anesthesia. This may imply on a higher risk of intraoperative hypertensive peaks with deleterious consequences for the patient. The objective of the present study was to evaluate the influence of the preoperative use o...
