title: Effect of verapamil on atherosclerosis.
abstract: Whether antihypertensive agents exert an antiatherosclerotic effect by blood pressure reduction or independently of their antihypertensive effect is clinically relevant. Animal studies have generally shown that the calcium antagonist verapamil has a preventive rather than a therapeutic antiatherosclerotic effect, which is independent of its antihypertensive effect. However, doses used in animal studies were much higher than those administered to humans and, in animals, the time of administration of verapamil coincided with the application of atherogenic stimulus. Human studies have given controversial results. Verapamil appears to effectively reduce the restenosis rate after coronary angioplasty. However, in patients with coronary stenosis who were undergoing bypass surgery, results were conflicting: a retrospective study provided positive results, while a prospective study gave negative results. An ongoing study investigating the effect of verapamil on the carotid arteries of hypertensive patients could help clarify the relationship between blood pressure reduction and the progression, regression or development of carotid lesions.
