BackgroundConsiderable evidence has been presented that heart and health-related quality of life are directly linked in patients with various diseases. This exploratory study investigated whether cardiac structure and function were associated with health-related quality of life in the general population.MethodsThis cross-sectional study was performed in five villages of Shunyi, a suburban district of Beijing, from June 2013 to April 2016. All inhabitants aged 35 years or older living in five villages of Shunyi were invited to participate. Exclusion criteria were individuals who declined participation, who had incomplete Health-related quality of life (HRQoL) data, and who had suboptimal echocardiograms. HRQoL was evaluated by the Mandarin version of SF-36. The association between the echocardiography-derived cardiac structure and function and each domain of SF-36 was analyzed by the multivariate linear regression analysis after adjusted for conventional risk factors affecting HRQoL.ResultsThe baseline data of 990 individuals were analyzed. The median age of the participants was 57 (50-63) years, and 367 (37.1%) were male, the average physical and mental component summary scores were 89.3 (79.8-94.3) and 90 (83.5-95) respectively. Tricuspid annular plane systolic excursion, an echocardiography-derived right ventricular parameter, was associated with all the subscales and summarized scores of SF-36 (all P<0.05). The independent association between tricuspid annular plane systolic excursion and physical/mental component summary scores remained after adjusting for age, gender, body mass index, education level, annual personal income, smoking and drinking status, and comorbidities (β=0.65, 95% confidence interval 0.30-1.01, P<0.01 and β=0.49, 95% confidence interval 0.23-0.76, P<0.01 for physical and mental component summary scores respectively). Compared with the participants with tricuspid annular plane systolic excursion ≥21 mm, the participants with tricuspid annular plane systolic excursion <21 mm had lower adjusted scores of physical and mental component summary scores (81.8 vs. 84.5, P=0.015, and 85.5 vs. 88.1, P<0.01 for physical and mental component summary scores respectively).ConclusionsIn this population-based study, right ventricular systolic function assessed by tricuspid annular plane systolic excursion was independently associated with health-related quality of life assessed by SF-36.
