Effect of maximum exercise on left ventricular deformation and its correlation with cardiopulmonary exercise capacity in competitive athletes.
Background: Global longitudinal strain (GLS) and global myocardial work index (GWI) allow early detection of subclinical changes in left ventricular (LV) systolic function. The aim of the study was to investigate the immediate effects of maximum physical exercise by different exercise testing methods on early post exercise LV deformation parameters in competitive athletes and to analyze their correlation with cardiopulmonary exercise capacity.
Methods: To reach maximum physical exercise, cardiopulmonary exercise testing (CPET) was performed by semi-recumbent ergometer in competitive handball players (n = 13) and by treadmill testing in competitive football players (n = 19). Maximum oxygen uptake (VO2max) indexed to body weight (relative VO2max) was measured in all athletes. Transthoracic echocardiography and blood pressure measurements were performed at rest and 5 min after CPET in all athletes. GLS, GWI and their changes before and after CPET (ΔGLS, ΔGWI) were correlated with (relative) VO2max.
Results: In handball and football players, GLS and GWI did not differ significantly before and after CPET. There were no significant correlations between GLS and relative VO2max, but moderate correlations were found between ΔGWI and relative VO2max in handball (r = 0.631; P = 0.021) and football players (r = 0.592; P = 0.008). Furthermore, handball (46.7 ml/min*kg ± 4.7 ml/min*kg vs. 37.4 ml/min*kg ± 4.2; P = 0.004) and football players (58.3 ml/min*kg ± 3.7 ml/min*kg vs. 49.7 ml/min*kg ± 6.8; P = 0.002) with an increased ΔGWI after CPET showed a significant higher relative VO2max.
Conclusion: Maximum physical exercise has an immediate effect on LV deformation, irrespective of the used testing method. The correlation of relative VO2max with ΔGWI in the early post exercise period, identifies ΔGWI as an echocardiographic parameter for characterizing the current individual training status of athletes.
期刊介绍：
Echo Research and Practice aims to be the premier international journal for physicians, sonographers, nurses and other allied health professionals practising echocardiography and other cardiac imaging modalities. This open-access journal publishes quality clinical and basic research, reviews, videos, education materials and selected high-interest case reports and videos across all echocardiography modalities and disciplines, including paediatrics, anaesthetics, general practice, acute medicine and intensive care. Multi-modality studies primarily featuring the use of cardiac ultrasound in clinical practice, in association with Cardiac Computed Tomography, Cardiovascular Magnetic Resonance or Nuclear Cardiology are of interest. Topics include, but are not limited to: 2D echocardiography 3D echocardiography Comparative imaging techniques – CCT, CMR and Nuclear Cardiology Congenital heart disease, including foetal echocardiography Contrast echocardiography Critical care echocardiography Deformation imaging Doppler echocardiography Interventional echocardiography Intracardiac echocardiography Intraoperative echocardiography Prosthetic valves Stress echocardiography Technical innovations Transoesophageal echocardiography Valve disease.
