Strain and myocardial work index during echo exercise to evaluate myocardial function in athletes

Abstract: The aim of the study was to evaluate the application of global longitudinal strain (GLS) and myocardial work (MW) at rest and during exercise in healthy sedentary or trained participants, to test their ability to improve echocardiographic information and to complement prescribing exercise, cardiac screening, or rehabilitation programs. Methods: Thirty healthy males were divided into three groups of 10, sedentary (G1), resistance (G2) and power (G3) athletes, underwent a standard clini… Show more

“…Therefore, the combination of longitudinal strains with afterload conditions, as is estimated in MW analysis, seems to be more accurate in evaluating the work of the separate segments [16,57]. The physiological remodeling of a healthy heart due to increased afterload during physical activity could be accompanied by increased absolute values of longitudinal strain and MW, which is, however, more homogenous than in MVP patients, and presents only during physical exercise, and does not lead to abnormal stretching [58]. In MVP patients, significantly increased regional longitudinal shortening with increased MW values present permanently, i.e., also at resting conditions, and may result in oxidative stress and possible fibrotic response [57]-a potential substrate for VA.…”

“…This discordance may be related to the impact on the diagnostic utility of GLS strain measurements of multiple factors such as preload, afterload, LV geometry, and sinus bradycardia [33,82,83]. However, these limitations could be overcome by measuring GLS in athletes during exercise [84].…”

“…In contrast to LVEF, GLS and GWI have been shown to be reliable in distinguishing between physiological adaption (e.g., LV hypertrophy due to exercise) and pathological changes (e.g., hypertrophic cardiomyopathy) in the athletes' heart 12,13 .…”
