Objective To study the clinical effects of Xinmailong Injection combined with nicorandil in treatment of elderly chronic heart failure with reduced ejection fraction. Methods A total of 124 patients with chronic heart failure with reduced ejection fraction in Xinxiang First People's Hospital from February 2016 to February 2018 were randomly divided into control group (n=62) and treatment group (n=62). The control group was po administered with Nicorandil Tablets, 5 mg/time, three times daily. The treatment group was given Xinmailong Injection on the basis of the control group, 5 mg/kg added into 100 mL normal saline to intravenous drip after skin test, 5 mg/time, twice daily. All patients were treated for 14 days. The clinical efficacy were compared, the changes of left ventricular structure and functional indicators, 6 min walking test (6MWT) before and after treatment were compared between the two groups. Results The effective rates in control and treatment groups were 80.65% and 93.55%, respectively, and the difference between the two groups was statistically significant (P<0.05). After treatment, LVEDD and LVESD decreased significantly in both groups (P<0.05), while LVEF increased significantly in both groups (P<0.05). After treatment, LVEDD and LVESD in the treatment group were lower than those in the control group, while LVEF was higher than that in the control group. The difference between the two groups was statistically significant (P<0.05). Conclusion Xinmailong Injection combined with nicorandil has good effects in treatment of chronic heart failure with reduced ejection fraction, and it can significantly improve the heart function and activity ability, which has a certain clinical application value.
