Abstract

Objectives: To assess the predictive value of the Global Registry of Acute Coronary Events (GRACE) discharge score for patients with stable coronary artery disease (SCAD) after percutaneous coronary intervention (PCI). Background: The GRACE score is widely used for predicting the mortality of acute coronary syndrome patients. However, the predictive value of SCAD has not been sufficiently studied. Methods: We studied 4,293 consecutive patients with SCAD who underwent PCI between January 2013 and December 2013. The primary endpoint was all-cause mortality and the secondary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE). Results: Among 3,915 patients with SCAD following PCI, there were 38 deaths and 394 MACCE during 2 years of follow-up. The GRACE discharge score was significantly higher for patients who died than for those who survived (86.97 ± 23.27 vs. 71.07 ± 19.84; p <.001). Risk stratification of the GRACE score indicated that the mortality risk of the intermediate-risk and high-risk groups were 3.23-fold (hazard ratio [HR], 3.23; range, 1.59–6.55; p =.001) and 15.31-fold higher (HR, 15.31; range, 4.43–51.62; p <.001), respectively, than that of the low-risk group. The MACCE risk for the intermediate-risk and high-risk groups were 1.28-fold (HR, 1.28; range, 1.02–1.62; p =.037) and 2.42-fold higher (HR, 2.42; range, 1.20–4.88; p =.014), respectively. The GRACE discharge score had prognostic value for mortality (area under the receiver operating characteristic curve, 0.692; p <.001). Conclusions: The GRACE discharge score is valuable for the risk stratification of death and MACCE, as well as for the prognosis to mortality for SCAD patients who have undergone PCI.
