Objective To study the effect of clopidogrel on serum inflammatory factors and echocardiography in patients with acute myocardial infarction complicated with heart failure.Methods60 cases of patients admitted in our hospital from July 2014 to August 2016 were selected as the research object in this study.They were randomly divided into the control group and the experimental group, each group had a total of 30 cases.Patients in the control group were treated with diuretics, nitroglycerin and aspirin, while the experimental group received clopidogrel on the basis of the control group.After treatment in June, comparative analysis of the experimental group and the control group of patients with treatment effect and related clinical indicators.ResultsAfter treatment, 6months after the corresponding, compared with before treatment, the experimental group and the control group of patients with C-reactive protein and vascular cell adhesion molecule 1, 6min mediated leukocyte walking experiment, Su-6 and the heart rate of treatment were improved, with statistical difference (P<0.05), left ventricular end diastolic there was no significant difference between the change in diameter.In the control group, C-reactive protein, vascular cell adhesion molecule 1, 6min walking test, interleukin-6 and heart rate were significantly better than those in the control group, with statistical difference (P<0.05).ConclusionThe application of clopidogrel in acute myocardial infarction complicated with heart failure in the can to a great extent on the inflammatory response in patients, improve the patient's left ventricular ejection fraction and heart rate, with the further promotion and application in clinical significance.
