Not all of the cardiovascular effects of angiotensin-converting enzyme (ACE) inhibitors can be attributed to changes in angiotensin II and bradykinin levels. Because the cytoplasmic tail of ACE is phosphorylated, we determined whether ACE inhibitors affect the phosphorylation of ACE and whether ACE possesses the characteristics of a signal transduction molecule. The ACE inhibitors ramiprilat an...

The beneficial effects of angiotensin I-converting enzyme (ACE) inhibitors go beyond the inhibition of ACE to decrease angiotensin (Ang) II or increase kinin levels. ACE inhibitors also affect kinin B1 and B2 receptor (B1R and B2R) signaling, which may underlie some of their therapeutic usefulness. They can indirectly potentiate the actions of bradykinin (BK) and ACE-resistant BK analogs on B2R...

To clarify the mechanisms by which angiotensin-converting enzyme (ACE) inhibitors lower blood pressure or inhibit cardiac hypertrophy, we analyzed the correlations among tissue ACE activities, blood pressure and cardiac hypertrophy. In spontaneously hypertensive rats (SHR), blood pressure, heart weight and ACE activities in plasma and various tissues were measured 3, 24 and 48 h after repeated ...

conclusions traditional medicine based on certain plants could be of beneficial effects in hypertension treatment. results in total, 52 species out of the 135 (39%) screened, gave more than 50% ace inhibition. forty species were found to possess a high ace inhibiting ability and were low in their tannin content. materials and methods in the present study 135 plants used in traditional persian m...

OBJECTIVES The purpose of this study was to investigate the significance of the possible negative interaction between aspirin and angiotensin-converting enzyme (ACE) inhibitors. BACKGROUND Several provocative reports have recently suggested that aspirin is unsafe in patients with heart failure and has negative interaction with ACE inhibitors that might attenuate their beneficial effects upon ...

ACE inhibitors have achieved widespread usage in the treatment of cardiovascular and renal disease. ACE inhibitors alter the balance between the vasoconstrictive, salt-retentive, and hypertrophic properties of angiotensin II (Ang II) and the vasodilatory and natriuretic properties of bradykinin and alter the metabolism of a number of other vasoactive substances. ACE inhibitors differ in the che...

BACKGROUND Aspirin and angiotensin-converting enzyme (ACE) inhibitors are recommended for secondary prevention after acute myocardial infarction (AMI), but several studies have suggested that the combination of these medications may produce a negative interaction. OBJECTIVE To evaluate the effect and interaction of aspirin and ACE inhibitors on mortality among elderly patients who survived a ...
