Abstract:
Objective: To explore the prevalence and risk factors of mitral regurgitation (MR) in the population ≥35 years in China in order to provide prevention reference for high risk crowd. Methods: The residents ≥35 years were taken by a stratified multistage sampling method. General information of crowd was collected by predesigned questionnaire and physical examination including life style, disease history, body weight and height. Echocardiography was conducted, fasting blood glucose and blood lipid levels were measured. Results: A total of 28814 subjects were enrolled. The overall MR detection rate was 18.4%, the detection rate in male and female were both 18.4%. The detection rates of moderate and severe MR were 0.3% in the paticipants at (35-50) years, 0.9% at (51-64) years and 2.2% at ≥65 years. MR prevalence showed an increasing trend with aging. Multivariate Logistic regression analysis indicated that age, systolic blood pressure, urban and rural, district, left atrial front and back diameter, left ventricular end diastolic front and back diameter, left ventricular ejection fraction, stroke, atrial fibrillation and heart failure were the risk factors for MR occurrence. Conclusion: MR detection rate was rather high in China. Specific prevention action should be taken for those with theabove risk factors.
