Abstract
Regardless of the mechanisms that initiate the rise of blood pressure, the development of structural changes in the systemic vasculature is the end result of established hypertension. Indices of small resistance artery structure, such as the ratio of tunica media to internal lumen, may have a strong prognostic significance in hypertensive patients, over and above all other known cardiovascular risk factors. Hence, the regression of vascular alterations seems to be an appealing goal for antihypertensive treatment. Different antihypertensive drugs may have different effects on vascular structure. Complete normalization of small resistance artery structure was demonstrated in hypertensive patients after long-term and effective antihypertensive therapy with angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, and calcium antagonists. Little or no improvement was observed with β-blockers or diuretics. Evidence from several studies suggests that some antihypertensive drugs are more effective than others in reversing microvascular structural alterations in hypertension.
