Background: It is established that physiologic cardiac remodeling occurs with high-intensity training in athletes. This study investigated importance of mass to volume ratios, relative wall thickness (RWT) and strain imaging in assessment of LV remodeling, addressing the implication of race and body composition.
Methods: A limited echocardiographic pre-participation screening protocol was performed in college footballers between 2007 and 2016. Baseline demographics were recorded at the time of image acquisition. LV mass and volumes were calculated by the 2D area-length method. LV function was assessed with LVEF and global longitudinal strain (GLS).
Results: A total of 241 players were screened; 7 were excluded due to pathologic echocardiographic findings and 5 were excluded due to incomplete or suboptimal imaging. Mean age and BMI were 18.5 ± 1.2 years and 29 ± 4kg/m2. 56.8% were Caucasian, 31.0% African American and 12.2% other. Mean LVEF was 58.8 ± 4.1% and LV mass 184 ± 33g. Players with a BMI > 30 had higher RWT and mass volume ratio (0.30 ± 0.02 vs 0.29 ± 0.03, p = 0.03 and 0.88 ± 0.09 vs 0.85 ± 0.09, p=0.04). RWT and LV mass to volume ratio were higher in African-American vs Caucasians (0.31 ± 0.03 vs 0.29 ± 0.02, p<0.01 and 0.91 ± 0.09 vs 0.83 ± 0.08, p<0.01). This difference was not observed in measures of LV function (Figure 1).
Conclusions: When assessing LV remodeling in college footballers it appears remodeling changes are more prominent than change in function and appear to be influenced by race and and body composition.
