Abstract:
Objective To explore the predictive value of coronary plaque burden for recurrent myo-cardial infarction in elderly patients with acute myocardial infarction(AMI)after PCI.Methods A retrospective study was conducted on 212 AMI patients undergoing PCI in our hospital from January 2019 to December 2021.All of them were followed up for 1 year after surgery,and were divided into a recurrent myocardial infarction group(32 cases)and a control group(180 cases)based on whether they had recurrent myocardial infarction or not.The clinical characteristics were compared between the two groups.ROC curve was plotted to analyze the predictive value of coro-nary plaque burden for recurrent myocardial infarction in elderly AMI patients.Results There was no statistical difference in the nutritional risk index between the two groups(P＞0.05).The carotid intima media thickness(1.44±0.17 mm vs 1.33±0.17 mm,P=0.000),non-calcified plaque burden[(15.45±3.08)％vs(9.72±2.69)％,P=0.000],calcified plaque burden[(22.07± 5.13)％vs(18.48±4.36)％,P=0.000],and total plaque burden[(37.52±6.18)％vs(28.20± 5.08)％,P=0.000]were significantly higher,while the LVEF value was lower[(58.09±7.16)％vs(66.50±7.83)％,P=0.000]in the recurrent group than the control group.Non-calcified plaque burden,calcified plaque burden,total plaque burden,carotid intima media thickness and LVEF were all valuable in predicting recurrent myocardial infarction in these patients after PCI(P＜0.05).The predictive value of non-calcified plaque burden was the highest,with an area under the curve of 0.906(95％CI:0.848-0.965,P=0.000).Conclusion Coronary plaque burden is of cer-tain value in predicting recurrent myocardial infarction in elderly AMI patients after PCI,and can be used to identify high-risk population for recurrent myocardial infarction.
