Investigation of epidemiologic features and treatment of chronic heart failure in some rural parts of Liaoning province.

Objective To evaluate the epidemiologic features and treatment of chronic heart failure in some rural parts of Liaoning province.Methods With the way of cluster random sampling method selected random samples aged 25~95 years were used to analyse the epidemiologic features and treatment of chronic heart failure(CHF) in different age and sex group in six countries of LiaoNing province.Results (1)A total of 33 027 cases were surveyed.The prevalence of CHF was 1.61%,0.95% and 2.28% in the general population,male population and female population,respectively.The females had CHF more frequently than the males (P0.005).The prevalence of CHF was 0.12%,0.79%,1.98%,3.71% and 7.51% in age groups of 25~34,35~44,45~54,55~64,65~74 years,respectively.The prevalence of CHF increased substantially with age.(2) The causes of CHF were coronary heart disease (68.36%),hypertension (13.37%),myocardiopathy(6.99%),rheumatic valvular disease(3.95%),congenital heart disease(1.69%) and other cardiovascular disease(5.27%).(3) The used drags were spironolactone(0.38%),angiotensin conversion enzyme inbibitors (ACEI)( 4.33%),and β-blockers (3.77%).Conclusion The epidemiological characteristics of the rural parts in our province show a trend close to the west coutries.There is still a gap in pharmacotherapy of heart failure.
