  1. Data were represented as means or percentage (95% CI)
  2. All values were weighted to represent the total population of Chinese aged 35 years or older based on the Chinese census 2010
  3. VHD, valvular heart disease; BMI, body mass index; AF, atrial fibrillation; HF, heart failure; DCM, Dilated Cardiomyopathy; HCM, Hypertrophic Cardiomyopathy; CHD, congenital heart disease; CKD, chronic kidney disease. LAap, the anteroposterior diameter of the left atrium; LVEDD, the diameter of the left ventricle at end-diastole; IVSd, the thickness of the interventricular septum; LVESD, the left ventricle end-systolic diameter; LVEF, the left ventricle ejection fraction
  4. P value for t-test (continuous) and x2 or Fisher’s exact test (categorical) to assess the difference between population with VHD and those without it
