Effect of Aging on Intraventricular Kinetic Energy and Energy Dissipation

In recent years, analysis of kinetic energy (KE) and the rate of kinetic energy dissipation (KED) or energy loss (EL) within the cardiac chambers, obtained by cardiac imaging techniques, has gained increasing attention. Thus, there is a need to clarify the effect of physiological variables, specifically aging, on these energetic measures. To elucidate this aspect, we reviewed the literature on this topic. Overall, cardiac magnetic resonance and echocardiographic studies published so far indicate that aging affects the energetics of left and right intraventricular blood flow, although not all energy measures during the cardiac cycle seem to be affected by age in the same way. Current studies, however, have limitations. Additional large, multicenter investigations are needed to test the effect of physiological variables on intraventricular KE and KED/EL measures.

Automated summary

In recent years, there has been increasing interest in studying the effects of aging on kinetic energy and kinetic energy dissipation within the cardiac chambers. Current studies using cardiac imaging techniques suggest that aging affects the energetics of left and right intraventricular blood flow, although the impact on different energy measures during the cardiac cycle may vary. However, more large-scale multicenter investigations are needed to fully understand the effects of physiological variables on intraventricular energy measures.
