Trend analysis on the mortality of cardiovascular diseases from 2004 to 2010 in China

Abstract

To explore the trend and characteristics of cardiovascular disease mortality in China. Mortality data from the National disease surveillance system from 2004 to 2010 was used. Underreporting was adjusted and trends were analyzed on the rates of crude mortality, standardized mortality and causes of death fraction among cardiovascular diseases. The total mortality of cardiovascular diseases increased from 240.03 to 268.92 per one hundred thousand during 2004 to 2010, with an average annual increase of 5.50 per one hundred thousand, with the annual increase of 2.17% . Data from all causes of death, ischemic heart disease, hypertensive heart disease, cerebrovascular disease, and other heart disease showed an upward trend, with the annual rise of 5.05%, 2.08%, 1.02% and 2.66% respectively while rheumatic heart disease showed a downward trend, with the declining rate of 7.02% per annum. After eliminating the effect of aging, the trend remained the same but the slope was decreasing. The proportion of national cardiovascular mortality on total deaths increased annually by 37.46% to 40.73% from 2004 to 2010. The proportion of cerebrovascular disease remained unchanging but the proportion of ischemic heart disease showed a significant increase. The proportion of rheumatic heart disease declined while the proportion of other cardiovascular disease mortality showing a slight change. In recent years, the cardiovascular mortality had significantly increased, which was mainly due to the increase of ischemic heart disease mortality.
