Objective To analyze the causes,cardiac function grading and drug application related to heart failure of the patients with chronic heart failure in Yongchuan district people's hospital.Methods The cases of chronic heart failure of department of cardiology in our hospital from January 1st,2012 to December 31st,2015 were counted and retrospectively analyzed.Results 3 320 cases of chronic heart failure in our hospital chosen from 8 126 medical records accounted for 40.86% of total discharged patients in the same period,including 2 262 cases of coronary disease (68.13%),353 cases of rheumatic heart disease (10.63%)and 265 cases of pulmonary heart disease (7.98%),who took up the top three in the spectrum of disease;2 683 cases of NYHA heart function Ⅲ magnitude accounted for 80.81%;The utilization rate of diuretic,digoxin,spironolactone,angiotensin -converting enzyme inhibi-tor,angiotonin receptor blocker,beta adrenergic receptor were 71.23%,27.23%,70.48%,30.75%,30.78%respectively.The statistical analysis showed that the differences were statistically significant between the patients using diuretics and the patients using spirolactone(χ2 =2.386,P <0.001),the patients with hypertension and the patients with no hypertension using ACEI /ARB(χ2 =2.727,P <0.001),and merged chronic bronchitis patients and the chro-nic bronchitis patients using beta -blocker(χ2 =61.807,P <0.001).Conclusion The patients with chronic heart failure takes up a higher portion among the inpatients in department of cardiology in the district level hospital.The heart function decreases significantly and the normative drug therapy needs to be improved.
