Abstract Objective Inadequate sleep is associated with increased risk of cardiovascular events; however, the associations between sleep duration or quality and cardiac function or structure are not well understood. This cross-sectional study was conducted to investigate to what extent sleep duration and quality are associated with left ventricular (LV) diastolic dysfunction or structural deterioration. Methods A total of 31,598 healthy Korean adults who received echocardiography and completed the Pittsburg Sleep Quality Index were enrolled in this study. Participants were stratified into three groups by self-reported sleep duration (i.e., <7, 7-9, >9 hours) and into two groups by subjective sleep quality. Sleep duration was also assessed as a continuous variable. The odds ratios for impaired LV diastolic function, increased relative wall thickness, and LV hypertrophy (LVH) were compared between groups using multivariable logistic regression analyses. Results After adjustment for confounding variables (e.g., age, smoking, body mass index), there was a statistically significant association between short sleep duration (<7 hours) and greater LVH (fully adjusted odds ratio = 1.32 [95% confidence interval {CI} = 1.02-1.73]). Short sleep duration was also significantly associated with greater LVH (0.87 per hour [95% CI = 0.78-0.98]) and increased relative wall thickness (0.92 [95% CI = 0.86-0.99]), but there was no significant association between sleep and LV diastolic function. Among individuals with normal sleep duration, poor quality of sleep was not associated with adverse cardiac measures. Conclusions These results indicate that short sleep duration (<7 hours) is associated with unfavorable LV structural characteristics. The association of insufficient sleep with adverse cardiovascular health outcomes may be mediated in part by adverse changes in cardiac structure and function.
