Abstract

Acute coronary syndrome (ACS) patients with diabetes have significantly worse cardiovascular outcomes than those without diabetes. This study aimed to compare the performance of The Thrombolysis In Myocardial Infarction (TIMI), Global Registry of Acute Coronary Events (GRACE), Primary Angioplasty in Myocardial Infarction (PAMI), and Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications (CADILLAC) risk scores in predicting long-term cardiovascular outcomes in diabetic patients with ST-segment elevation myocardial infarction (STEMI). From the Acute Coronary Syndrome-Diabetes Mellitus Registry of the Taiwan Society of Cardiology, patients with STEMI were included. The TIMI, GRACE, PAMI, and CADILLAC risk scores were calculated. The discriminative potential of risk scores was analyzed using the area under the receiver-operating characteristics curve (AUC). In the 455 patients included, all four risk score systems demonstrated predictive accuracy for 6-, 12- and 24-month mortality with AUC values of 0.67-0.82. The CADILLAC score had the best discriminative accuracy, with an AUC of 0.8207 (p<0.0001), 0.8210 (p<0.0001), and 0.8192 (p<0.0001) for 6-, 12-, and 24-month mortality, respectively. It also had the best predictive value for bleeding and acute renal failure, with an AUC of 0.7919 (p<0.05) and 0.9764 (p<0.0001), respectively. Patients with CADILLAC risk scores >8 had poorer 2-year survival than those with lower scores (log-rank p<0.0001).
