Abstract：Objective To analyze the clinical characteristics of patients with heart failure after acute myocardial infarction.Methods A total of 90 patients with acute myocardial infarction (AMI)admitted to the Second Hospital of Nanping City,Fujian Province from April 2019 to April 2020 were selected retrospectively as the research subjects.Patients were divided into two groups according to whether patients complicated with heart failure or not.56 patients without complicated with heart failure were included in the single myocardial infarction group,and 34 patients with complicated with heart failure were included in the combined heart failure group.The clinical characteristics of the two groups were compared.Results The age,proportion of female in the combined heart failure group were higher than those in the single myocardial infarction group,and the differences were statistically significant(P＜0.05).There were no significant differences in the rates of hypertension,diabetes,hyperlipidemia,smoking history and coronary artery bypass transplantation between the two groups (P＞0.05).In terms of biochemical indicators,systolic blood pressure,diastolic blood pressure and hemoglobin in the combined heart failure group were lower than those in the single myocardial infarction group,and the levels of serum creatinine,serum uric acid,creatine kinase and brain natriuretic peptide were higher than those in the single myocardial infarction group,the differences were statistically significant(P＜0.05).There were no significant differences in total cholesterol,triglyceride and low density lipoprotein cholesterol levels between the two groups (P＞0.05).In terms of drug use,the utilization rate of diuretics in the combined heart failure group was higher than that in the single myocardial infarction group,and the utilization rate of β-blockers and angiotensin converting enzyme inhibitor/angiotensin receptor blockers was lower than that in the single myocardial infarction group,the differences were statistically significant(P＜0.05).There were no significant differences in the use rates of interventional therapy,statins,aspirin and clopidogrel between the two groups (P＞0.05).The length of hospital stay in the combined heart failure group was longer than that in the single myocardial infarction group,and the difference was statistically significant(P＜0.05).There was no significant difference in the rate of heart rupture,renal insufficiency,malignant arrhythmia,ventricular aneurysm and embolism,death in the combined heart failure group compared with those in the single myocardial infarction group (P＞0.05).Conclusion The clinical characteristics of patients with heart failure after AMI are somewhat different from those of single AMI,and the prognosis of patients with acute myocardial infarction complicated with heart failure is worse and the risk of death is higher.Interventional therapy is a protective factor for prognosis.
