Abstract
Objective To analyze the predictive value of heart rate deceleration capacity(DC)and QT dispersion(QTd)for major adverse cardiovascular events(MACEs)in patients with acute myocardial infarction(AMI).Methods A retrospective analysis was conducted on 80 AMI patients who had all undergone percutaneous coronary intervention(PCI),designated as an observation group.Based on the occurrence of MACEs during follow-up,they were further divided into an occurrence group(20 cases)and a non-occurrence group(60 cases).Additionally,80 healthy examinees during the same period were selected as a control group.Heart rate DC and QTd were compared between the observation group and the control group,as well as between the occurrence group and the non-occurrence group from the observation group.The predictive value of heart rate DC and QTd for MACEs in AMI patients was analyzed by using ROC curve analysis.Results Among the 80 AMI patients in the observation group,20 experienced MACEs during follow-up,accounting for 25.00％(20/80).The heart rate DC in the observation group was significantly lower than that in the control group,while the QTd was significantly higher(both P＜0.01).The heart rate DC in the occurrence group was lower than that in the non-occurrence group,and the QTd was higher(both P＜0.01).ROC curve analysis showed that the combined assessment of heart rate DC and QTd had a higher predictive value for MACEs in AMI patients(AUC=0.958)compared to either parameter alone(AUC=0.895 and 0.812,respectively).Conclusion Heart rate DC and QTd could predict the risk of MACEs in AMI patients,and their combined use offers higher predictive value.关键词
