Abstract:

Objective To explore the clinical implications of different evaluation methods and value for the prediction of spontaneous reperfusion in ST-segment elevation myocardial infarction (STEMI). Methods A total of 260 patients who underwent coronary angiography (CAG) were enrolled. The patients were divided into spontaneous reperfusion (SR, TIMI flow grade 3 identified by CAG) group (n=67) and nonspontaneous reperfusion (NSR, TIMI flow grade 0-2 identified by CAG) group (n=193). We analyzed the predictive value of ST-segment resolution (STR), hemoglobin (Hb), and high-sensitivity C-reactive protein (hsCRP) in SR in acute myocardial infarction (AMI). Results There was significant difference in ST-segment resolution, symptoms release, Hb, creatinine, uric acid, MB isoenzyme of creatine kinases, and hsCRP between two groups. In Logistic regression model, Hb (OR=1.064,95%CI:1.036-1.094,P=0.000), hsCRP (OR=0.811,95%CI:0.713-0.923,P=0.001) and STR>50% (OR=3.638,95%CI:1.793-7.318,P=0.000) were independent predictors for SR. The receiver-operating characteristic curve (ROC) analysis for Hb, hsCRP, and STR combined in predicting spontaneous reperfusion showed sensitivity of 80.6%, specificity of 63.7%, and area under the curve (AUC)=0.78(0.72-0.85). Conclusion Hb, hsCRP and STR have predictive value for SR.
