Left ventricular hypertrophy (LVH) is recognized as a component of athlete's heart and has been widely reported in elite athletes. However, there are few reports on the prevalence and persistence of LVH in elite athletes following retirement.
Former professional football players (n = 1172) were sampled for demographics, blood pressure, anthropometry, and 2D echocardiogram. Left ventricle mass was indexed to body surface area to obtain left ventricle mass index (LVMI). Subjects were stratified by age and playing position group. Statistical analysis included ANOVA, T-test, and Chi-square where appropriate.
The population prevalence of LVH was 12.3%. Age and position group contrasts are reported in Table 1. There was a significant effect of playing position (p = 0.0388) but not age (p = 0.0846) on LVH prevalence (Table 1). Blood pressure was higher in subjects with severe LVH versus normal LVMI (p = 0.0059), and subjects with hypertension (HTN) tended to have a higher prevalence of LVH (p = 0.0753). Detraining time had no effect on the prevalence (p = 0.1443) or type (p = 0.2152) of LVH.
Despite considerable time detrained, LVH appears to persist in some former players and is likely the result of various factors including body size, HTN, and age. Position-specific training may also play a role in the development, type, and persistence of LVH. Further research is warranted to understand the clinical consequences of this factor on potential cardiovascular risk later in life.
