Research Agenda for Cardiovascular Aging: Humans to Molecules

Clinical manifestations of specific cardiovascular diseases, e.g., atherosclerosis and hypertension, that lead to heart failure and stroke likely become altered in older persons of advanced age because interactions occur between age-associated cardiovascular changes in health and specific pathophysiologic mechanisms that underlie cardiovascular diseases. The interactions result in a lower threshold for clinical symptoms, and greater severity and poorer prognosis of these diseases in older vs. younger persons. In this regard, cardiovascular changes that occur during aging in health ought not to be considered to reflect a "normal process"; rather these specific age-associated changes must be construed as specific "risk factors" for the aforementioned cardiovascular diseases and ought to become targets of interventions designed to prevent the epidemic of cardiovascular disease in later life. Such a strategy would thus advocate preventive treatment for what is now considered to be "normal cardiovascular aging." Effective and efficient prevention of the "risks" associated with cardiovascular aging in apparent health requires a fundamental understanding of these changes ranging in scope from humans to molecules. An opinion regarding specific directions for research aimed toward the achievement of this understanding is provided. (c) 2000 by CVRR, Inc.
