AbstractObjective: To investigate the clinical characteristics and pharmaceutical therapy of elderly patients with chronic heart failure (CHF). Methods: Using the multi-center retrospective cross-sectional survey, we analyzed 1 799 hospitalized patients with CHF as the main cause and NYHA heart function classification Ⅱ-Ⅳ from nine tertiary hospitals of Tianjin during March 2014 to February 2016. According to age, we divided them into non- elderly group(age<65 years), normal elderly group (age ≥65-79 years), and the old elderly group(age≥80 years). We analyzed the clinical characteristics and pharmaceutical therapy of different age groups of CHF patients. Results: One thousand seven hundred and ninety-nine patients with CHF, mean age (70±13) years old. Elderly patients over 65 accounted for 69.87%; men accounted for 61.53%; the average hospitalization days were 11.33 days, hospitalization days of the old elderly group were significantly prolonged to 13.26 days(P<0.05). With increasing age, the proportion of men, NYHA Ⅱ and HFrEF patients gradually decreased, the proportion of women, NYHA Ⅳ and HFpEF patients gradually increased(all P<0.05). The distribution of HFmrEF in different age groups was not statistically significant(P>0.05), accounting for one third. Etiology and comorbidities: the first eight diseases were coronary heart disease, hypertension, hyperlipidemia, diabetes, pulmonary infection, cerebrovascular disease, renal dysfunction and atrial fibrillation. The ratios of old elderly group with pulmonary infection, cerebrovascular disease, renal dysfunction and atrial fibrillation were significantly higher than the non-elderly group( all P<0.05). The numbers of comorbidity in old elderly group and the normal elderly group were higher than the non-elderly group, respectively 3.74, 3.37 and 2.82(all P<0.05). The application rate of β-blockers and ACEIs in non-elderly group was higher than the other groups (P<0.05). The application rate of ARBs, digitalis, energy metabolites and nitrates in the normal elderly group and the old elderly age group was higher than the non-elderly group (P<0.05). Conclusions: With increasing age, the proportion of men and HFrEF patients with CHF gradually decrease, the proportion of women and HFpEF patients with CHF gradually increase, the proportion of old elderly men and women tend to be equal, HFmrEF maintains the proportion of about 1/3, no change with age. The elderly patients with CHF have more comorbidity, worse heart function, and more serious heart failure.The overall application of anti-HF drugs in elderly CHF patients needs to be improved.
