| Objective:To explore the effect of EECP therapy on patients with AMI after emergency PCI.Methods:From October 2015 to December 2016,patients diagnosed with acute myocardial infarction in the Second Affiliated Hospital of Henan University of Science and Technology were treated with PCI and were divided into two groups according to the random number table method: the control group and the counterpulsation group.1weeks after PCI,the heart pain episodes in the counterpulsation group and the control group were observed,compared and analyzed,the changes in electrocardiogram,the changes of the color Doppler indexes reflecting the left ventricular function,and the Killip classification of the one week after the operation;and then sixth months and twelfth months after the operation,respectively,to record the occurrence of MACE and the function of the heart.To evaluate the therapeutic effect of EECP on PCI after acute myocardial infarction.Finally,according to the results of the return visit,Kaplan-Meier survival analysis was used to test the endpoint events of the patients in the control group and the counterpulsation group,and to analyze the occurrence of the survival outcome of the counterpulsation group and the control group.Results:The general data of the selected patients showed that there was no statistical difference in the general data of the counterpulsation group and the control group,and could carry out the follow-up study.After a comparative study,the following results are obtained.1.After PCI operation,after EECP early treatment,the heart pain frequency and duration of heart pain in the counterpulsation group and the control group were significantly different,and the counterpulsation group was significantly lower than the control group in the frequency of heart pain and the time of heart pain.2.After PCI,the patients with acute myocardial infarction were treated by early EECP,and the results of electrocardiogram evolution in the two groups after 1 weeks were analyzed.The total effective rate of electrocardiogram in the counterpulsation group was significantly higher than that of the control group.3.Patients with acute myocardial infarction were treated by PCI,and after theearly treatment of EECP,the echocardiographic indexes of left ventricular function were analyzed in the two groups after seventh days of operation.There were significant differences between the two groups in the left ventricular ejection fraction,left ventricular end systolic volume and stroke output,and the counterpulsation group was compared with the control group on these three indexes.There was a significant advantage;there was no difference in left ventricular end diastolic volume and E/A peak ratio between the two groups.4.Patients with acute myocardial infarction were treated with EECP early after PCI,and seventh days after PCI,two groups of patients were classified by Killip.After analysis,the results showed that the >I grade of Killip in the counterpulsation group was 12%,and the >I grade of the Killip grade in the control group was 28.4%.Patients with acute myocardial infarction underwent PCI after regular EECP treatment for 1 courses.They were followed up for sixth months after operation.The results showed that there was a decrease in MACE events in the treatment of PCI after EECP for acute myocardial infarction,and the heart function of the patients was evaluated by the New York cardiac function classification(New York Heart function assessment,NYHA),and the cardiac function of the counterpulsation group was better than that of the control group.After PCI operation,the patients with acute myocardial infarction were treated with regular EECP for 1 courses and returned to visit twelfth months after the operation.The results showed that the incidence of MACE events,such as cardiac death,non fatal acute myocardial reinfarction,angina,heart failure and revascularization in the counterpulsation group,was lower than that of the control group;New York heart was used.Functional classification(NYHA)was used to evaluate the cardiac function of patients.The cardiac function of patients in the counterpulsation group was improved compared with that in the control group.After twelfth months of follow-up after PCI,combined with the results of return visit,Kaplan-Meier survival analysis was used to test the end events(death)of the patients in the control group and the counterpulsation group.The results showed that there were significant statistical differences in the survival curves of the two groups(p<0.05).Conclusions:1.The immediate blood flow effect of EECP can improve the patients' acute stage symptoms and improve the left ventricular function.In subacute phase,the patient's heart function can be maintained and the incidence of MACE events is reduced.2.AMI patients underwent PCI,early EECP treatment for 1 courses can improve the survival state of patients. |
