How Does Aging Affect Lusitropy?

By age 80, the heart's early diastolic filling rate can be reduced by as much as 50% in healthy individuals, a clear sign of impaired lusitropy. This reduction in the heart's ability to relax is a hallmark of aging, impacting cardiac function and reserve capacity. Understanding how aging affects lusitropy is crucial for grasping the physiological changes that occur in the cardiovascular system over time.
