Enlarged left ventricle, aortic root dilation, and obstructive sleep apnea (OSA) have been reported as findings in retired professional football players. However, there are few studies examining the relationship between OSA risk and left ventricular hypertrophy (LVH) or aortic root dilation in this population.
Former professional football players (n = 1172) were sampled for demographics, blood pressure, anthropometry, and 2D echocardiogram. Left ventricle mass (LVM) and aortic root at the Sinus of Valsalva were indexed to body surface area to obtain left ventricle mass index and indexed aortic root (LVMI and IAR, respectively). OSA risk was assessed via the STOP-BANG questionnaire. Statistical analysis included ANOVA, Pearson product moment, T-test, and Chi-square where appropriate.
High OSA risk was associated with increased blood pressure (p < 0.0001), LVM (p < 0.0001), LVH prevalence (p = 0.0103), and distribution of concentric versus eccentric LVH (p < 0.0001) as compared with low OSA risk; however, there was no effect of OSA risk on LVMI (p = 0.1413). Blood pressure and hypertension prevalence were greater in subjects reporting incidents of apneic breathing during sleep as compared with those reporting no such events (systolic blood pressure: p = 0.0215; diastolic blood pressure: p = 0.0069; hypertension: p = 0.0279); likewise, LVM and LVMI were greater in subjects reporting incidents of apneic breathing during sleep versus those reporting no events (p < 0.0001 for each). However, LVH prevalence did not differ between those reporting sleep apneic events and those not (p = 0.4481). While IAR was lower in subjects with high OSA risk (p = 0.0004) and reporting apneic events during sleep (p = 0.0322), there was no effect of OSA risk on aortic root dilation prevalence (p = 0.2209).
There is an association between OSA risk and both increased LVM and LVH in this former professional football player population, although this was not observed for aortic root dilation. Given the potential implications of LVH on future cardiovascular disease risk, OSA risk and history of sleep apnea should be considered when assessing cardiovascular risk in men within this population.
