Using a large echocardiography database in our center, we analyzed trends in the prevalence of several common heart diseases from Dec. 2003. This study retrospectively analyzed the echocardiographic database in our Department from 2003 to 2012. A total of 385 682 cases were included in the study. The prevalence of rheumatic heart disease decreased over the 10-year period, from 4.04% in 2003 to 3.06% in 2012 （P〈0.01）. Infective endocarditis also decreased, from a mean prevalence of 0.37% in July 2003 to 0.27% in Dec. 2008 （P〈0.001）. The prevalence of hy- pertrophic cardiomyopathy, which includes 20% apical hypertrophic cardiomyopathy and 20% hypertrophic obstructive cardiomyopathy, was about 1.8%. The prevalence of the three most common adult congenital heart diseases （CHDs） decreased by about 10% from July 2003 to Dec. 2008 （all P〈0.001）. The prevalence of moderate pulmonary arterial hypertension （PAH） or left ventricular systolic dysfunction （LVSD） decreased during the 10-year period （P〈0.001）, but there was no change in the prevalence of severe PAH or LVSD （P〉0.05）. The present study indirectly demonstrates that the prevalence of several common heart diseases in China has declined in recent years.展开更多
