Objective To investigate the prevalence and distributing feature of chronic heart failure (CHF) in Xin jiang adult population.

Methods Four-stage selected random samples Maternal Age 35 and over were used to analyse the prevalence and distributing feature of self-reported congestive heart failure in different nationality, age, sex and The sampled adult population were collected 6 locality (Urumqi, Ke lamayi, Fu kang, the Turfan Basin locality, He tian locality, Yi li Hazakh autonomous prefecture) from 23 municipalities and 7 locality and 5 autonomous county in Xin jiang.
