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.
近年来,通过心脏成像技术获得的心脏腔室内动能(KE)以及动能耗散率(KED)或能量损失(EL)的分析受到了越来越多的关注。因此,有必要阐明生理变量,特别是衰老,对这些能量指标的影响。为了阐明这一方面,我们回顾了关于该主题的文献。总体而言,迄今为止发表的心脏磁共振和超声心动图研究表明,衰老会影响左、右心室内血流的能量学,尽管心动周期中的并非所有能量指标似乎都以相同方式受到年龄的影响。然而,目前的研究存在局限性。需要更多大型多中心研究来测试生理变量对心室内KE和KED/EL指标的影响。
