Assessment of left ventricular systolic function using a non-invasive index of myocardial work in amateur marathon runners.

ABSTRACT:

Background

For non-professionally trained athletes, the hyperphysiological stress response induced by marathon exercise may lead to heart fatigue and even cause organic changes such as abnormal ventricular septal thickening. Early detection of abnormal cardiac function in athletes can help prevent adverse cardiovascular events. The purpose of this study was to analyze the left ventricular systolic function (LVSF) of amateur marathon runners using a novel technique called the left ventricular (LV) pressure-strain loop (PSL).

Methods

A total of 35 amateur marathon runners and 33 age-matched healthy controls from Hangzhou were enrolled in this cross-sectional study from October 2021 to August 2023. The LV myocardial work (MW) parameters were calculated as the area of the PSL by
