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 inhibitor, 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 chronic bronchitis patients using beta-blocker(χ2=61.807, P<0.001).
