Predictive value of myocardial contrast echocardiography for heart failure after PCI in STEMI patients
[Objective]To study the predictive value of myocardial contrast echocardiography(MCE)for heart failure(HF)after percutaneous coronary intervention(PCI)in patients with ST-segment elevation myocardial infarction(STEMI).[Methods]A total of 140 STEMI patients admitted to Zhoukou Central Hospital from December 2019 to December 2022 were selected,all of whom underwent PCI,and were divided into HF group(36 cases)and non-HF group(92 cases)according to whether HF occurred within 30 d after surgery.The general data and MCE quantitative parameters A value,κ value,A×κ value of the two groups were compared.Logistic regression model was used to analyze the influencing factors of HF after PCI in STEMI patients.Receiver operating characteristic(ROC)curve was drawn to analyze the efficacy of A value,κ value,Ax κ value alone and combined in predicting HF after PCI in STEMI patients.[Results]Compared with non-HF group,the age in HF group was older(P＜0.05),the percentage of diabetes history,coronary Gensini score and serum creatine kinase-MB(CK-MB)level were higher(P＜0.05),the time from onset to infarction vessel opening was longer(P＜0.05),and the A,κ and Ax κ were lower(P＜0.05).Logistic regression model showed that age,coronary Gensini score,opening time from onset to infarction vessel,A,κ and A× κ were the influencing factors of HF after PCI in STEMI patients(P＜0.05).ROC curve showed that,compared with the separate test of A value,κ value and Axκvalue,the sensitivity of the combined test was increased(x2=4.600,P=0.032,x2=6.821,P=0.009,x2=8.036,P=0.005),the AUCs of A value,κ value and A×κ value in predicting HF after PCI in STEMI patients were 0.834(95％CI:0.758-0.894),0.773(95％CI:0.691-0.842)and 0.802(95％CI:0.722-0.867),respectively,and the AUC of the combination of the three was 0.908(95％CI:0.844-0.952).Pairwise algorithm test showed that compared with A value,κ value and A× κ value alone,the AUC of the combination of the three increased(Z=2.295,P=0.022,Z=3.468,P=0.001,Z=2.774,P=0.006).[Conclusion]MCE quantitative parameters have a high predictive value for HF after PCI in STEMI patients.
