Age Related Changes in Cardiac Physiology as a Predictor of Exercise

Status Completed

Clinical Trial Summary

Aging is associated with numerous changes and adaptations in the cardiovascular system. Vascular and ventricular wall thickness increase, whereas arterial compliance, endothelial function, and ventricular contractility decline. The decline in cardiac function with advancing age is typically seen in parallel to reduced physical activity, and it has been proposed that lifelong exercise training might attenuate the effects of aging on the heart.

The cardiovascular system undergoes several age-related changes. For most healthy older individuals, the heart generally functions well under resting conditions. Structural and physiological changes tend to result in diminished exercise tolerance. However, increasingly it has been shown that even some of these changes are more a result of a sedentary lifestyle than an age-related phenomenon. Most elderly people tend to become less physically active. It is difficult to separate changes intrinsic to the aging process from those arising as a result of a sedentary lifestyle.

Clinical Trial Description

Previous large studies have concluded that resting LV diastolic and systolic function decline with age. The cardiovascular system undergoes several age-related changes. For most healthy older individuals, the heart generally functions well under resting conditions. Structural and physiological changes tend to result in diminished exercise tolerance. However, increasingly it has been shown that even some of these changes are more a result of a sedentary lifestyle than an age-related phenomenon. Most elderly people tend to become less physically active. It is difficult to separate changes intrinsic to the aging process from those arising as a result of a sedentary lifestyle. Studies of aging and physical activity usually compare older athletes with sedentary ones, in which physical activity was not found to attenuate the impact on the aging heart. Thus, the investigators set of to find the difference between hearts of elderly who are physically fit as measured with METS to those who are not. And try and understand the basis of this difference. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
