Predictive accuracy of PAMI, TIMI, CADILLAC and GRACE scoring models for 2-year mortality.

According to the tertiles of each risk score, patients with the higher tertile (T3) of each risk score had unfavorable 2-year survival than those with middle tertile (T2) and lower tertile (T1) of each risk score (Fig 2). However, there was no death subjects in T1 and T2 of the CADILLAC score group. We further found the best cut-off point for the CADILLAC risk score (8 points) by using Youden’s index (Table 5). Since the CADILLAC risk score had the best predictive accuracy for mortality, we used it to estimate the survival rate at 2 years, as shown in Fig 3. Patients with CADILLAC risk scores >8 had poorer 2-year survival than those with risk scores ≤8 (both log-rank p<0.0001).
