Sleep Duration and Quality as Related to Left Ventricular Structure and Function

ABSTRACTObjectiveInadequate 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.MethodsA 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., 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.ResultsAfter adjustment for confounding variables (e.g., age, smoking, body mass index), there was a statistically significant association between short sleep duration (
