Arterial and Cardiac Aging: Major Shareholders in Cardiovascular Disease Enterprises

E vidence supporting the hypothesis that age-associated changes in cardiovascular structure/function are implicated in the markedly increased risk for cardiovascular disease in older persons has been presented in the preceding 2 articles in this series. It follows that therapies to prevent or delay cardiovascular changes that accompany aging may reduce the risk for age-associated cardiovascular diseases. Understanding the nature and effectiveness of such therapies, however, requires an understanding of heart and arterial aging at the cellular and molecular levels. Fortunately, many of the age-associated changes in cardiac and arterial structure or function that have been observed in humans also occur across a…
