ABSTRACT

<p><b>OBJECTIVE</b>To investigate the prevalence and distributing feature of chronic heart failure (CHF) in adult population of Xinjiang.</p><p><b>METHODS</b>Four-stage random sampling method was used to analyze the prevalence and distributing feature of self-reported congestive heart failure among different nationalities in adult (35 years and over) population of Xinjiang. Sampling was collected from 6 localities (Urumqi, Kelamayi, Fukang, Turfan Basin, Hetian, Yili Hazakh).</p><p><b>RESULTS</b>A total of 8459 adults were surveyed. The prevalence of CHF was 1.26% in this cohort. The prevalence of CHF was 0.89%, 1.11% and 2.14%(*) in Han, Uygur and Hazakh population, respectively ((*)P < 0.05 vs. Han and Uygur). The risk of CHF was higher in the males than in the females (1.61% vs. 0.93%, u = 2.79, P < 0.05). The prevalence of CHF increased in proportion with aging and was 0.29%, 0.60%, 1.32%, 2.55% and 4.10% in 35 - 44, 45 - 54, 55 - 64, 65 - 74, 75 years and over age groups, respectively. Common complications of CHF were hypertension (63.55%), coronary heart disease (42.99%), diabetes (18.69%), valvular heart disease (5.61%) and atrial fibrillation (4.67%).</p><p><b>CONCLUSION</b>The prevalence of CHF in Xinjiang was higher than the average level in China (0.9%) and was the highest in the Hazakh population.</p>
