Long-term treatment with angiotensin-converting enzyme (ACE) inhibitors as well angiotensin II type 1 (AT(1)) receptor antagonists and statins reduces cardiovascular mortality in patients coronary artery disease chronic heart failure. Little is known about the acute effects of these compounds on vascular reactivity resistance vessels. Coronary arterioles were obtained from undergoing bypass operation (atherosclerosis group) or valve replacement (control group). Responses to...
