Arteriosclerosis is the hallmark of hypertension and of its complications, namely stroke, coronary artery disease and ischaemic renal failure. The earliest morphological change in the arteriosclerotic process is vascular smooth muscle hypertrophy and hyperplasia. Angiotensin II is an important growth factor in vascular smooth muscle cells. The chronic administration of ACE inhibitors will reverse many of the changes of vascular hypertrophy in experimental animal models, and will improve vascular compliance in hypertensive patients. Some differences have been reported between different ACE inhibitors with respect to blood pressure-lowering effect and regression of medial hypertrophy in spontaneously hypertensive rats.
