Abstract
Angiotensin II plays an important role in neointimal formation after vascular injury. Our objectives were 1) to investigate the difference between angiotensin converting enzyme inhibitors (captopril, delapril) and an angiotensin II subtype 1 (AT1) receptor antagonist (DuP753) in suppressing neointimal proliferation; and 2) to investigate the antiproliferative effects of these drugs given topically to the injured vessels. All these treatments effectively prevented neointimal formation (p<0.01). Even a single topical application of either type of drug with F127 pluronic gel to the injured vessel after ballooning is found to be significantly effective probably due to the inhibition of smooth muscle cell migration (p<0.01). Multiple systemic application of angiotensin converting enzyme inhibitors was more effective than that of DuP753 at the same blood pressure level. The effectiveness of topical application of these drugs suggests clinical usefulness after angioplasty or vascular surgery.
