Abstract:
Objectives: To explore the impact of strength sport on heart structure by echocardiography (ECHO) and cardiac resonance imaging (CMR). Methods: This is a case control study. A total of 14 male weightlifter athletes who underwent physical examination in Peking University Third Hospital from January 16, 2019 to November 1, 2019 were included in this study. Fourteen age-matched healthy Chinese men served as the control group. ECHO and CMR were used to detect the heart structure and function of the participants. Results: The age of athlete group was (21±3) years, and the training time was (9±4) years. The weekly exercise time of athlete group was more than 15 hours, while that of control group was less than 3 hours. ECHO-derived interventricular septal (IVS) thickness value ((9.3±1.3) mm vs. (8.1±0.5) mm, P=0.006) and CMR-derived IVS value ((11.0±1.5) mm vs. (10.0±0.5) mm, P=0.003) was both significantly higher in the athlete group than in the control group. For the athlete group, the indicators of left ventricular volume measured by ECHO (left ventricular end diastolic volume (LVEDV), left ventricular end diastolic volume index (LVEDVI), left ventricular end systolic volume, left ventricular end systolic volume index) and IVS thickness were significantly lower than those measured by CMR (all P<0.05). Left ventricular ejection fraction ((67.0±3.8)% vs. (59.0±3.9)%, P<0.001) and left ventricular global longitudinal strain ((19.3±2.9)% vs. (11.2±1.2)%, P<0.001) values measured by ECHO were significantly higher than those measured by CMR. There was no significant difference in the proportion of subjects with the left ventricular end diastolic diameter, LVEDV and LVEDVI above the upper limit of normal as measured by ECHOs and CMR (all P>0.05). IVS values measured by ECHO were all within the normal range, and CMR showed that 9 (9/14) weightlifter athletes had IVS>11 mm with a maximum thickness of 13.8 mm, which occurred in the inferoseptum. Conclusion: Weightlifter sport could result in thickening of the left ventricular inferoseptum, and CMR is superior to ECHO in detecting the thickening of the left ventricular wall, which serves as a helpful tool for sports medicine supervision.
