INTRODUCTION: Acute coronary syndromes (ACS), which also include ST Elevation Myocardial Infarction (STEMI), are most responsible for cardiac deaths. With the correct, rapid diagnosis and appropriate treatment option, all adverse events, including death, can be reduced. For this purpose, risk scoring has been developed and used in daily practice. In our study, we aimed to evaluate the place of risk scores used to evaluate mortality in STEMI patients in predicting coronary artery disease (CAD) severity.
METHODS: In our study, 293 STEMI patients were enrolled. All of these patients underwent coronary angiography, and GRACE, TIMI, Zwolle, PAMI, CADILLAC risk scores and SYNTAX score (SS) were calculated. The distinguishing ability of mortality risk scores was assessed using the area under the curve or the C statistical method.
RESULTS: The number of patients with high SS was 112 (%38.2). Compared to the ROC curves of the risk scores in determining the presence of severe CAD, all of the results were significant, similar, and had a high predictive value. The area under the curve values of severe CAD, TIMI, Zwolle, PAMI and CADILLAC were found to be 0.658, 0.675, 0.716, 0.679 and 0.703, respectively (p<0.001).
DISCUSSION AND CONCLUSION: Mortality risk scores were similar, significant and effective in predicting high SS, the highest rate being Zwolle score, in patients admitted to our clinic with STEMI. Using these risk scores in a simple and fast way before and after coronary angiography, it will provide us an important benefit for predicting mortality and predicting the presence and severity of CAD.
