Predicted and observed in-hospital mortality after left main coronary artery stenting in 204 patients.

Abstract：

BACKGROUND:The purpose of this study was to compare risk predicted using available risk scores and actual outcomes in patients with left main coronary artery disease undergoing percutaneous coronary intervention with stent implantation (PCI LM). METHODS:We studied 204 patients treated with elective or emergent coronary angioplasty. We estimated in-hospital mortality using the EuroSCORE, Parsonnet and GRACE risk scores and compared this data with actual in-hospital mortality. RESULTS:There were no deaths among 62 patients undergoing elective PCI LM regardless of the estimated risk. Acute coronary syndrome (ACS) was diagnosed in all 142 patients undergoing emergent PCI LM. Mortality in this group was 24% (34/142). Area under receiver operating characteristic curve (AUC) values for the EuroSCORE, Parsonnet and GRACE risk scores in patients with ACS were 0.812 (p = 0.0001), 0.857 (p = 0.0001), and 0.870 (p = 0.0001), respectively. No statistically significant differences were found when these AUC values for different evaluated risk scores were compared. Overall, the EuroSCORE and Parsonnet risk scores had no discriminative value, as all deaths occurred in the highest risk group. Only the GRACE risk score discriminated risk among intermediate- and high-risk patients with ACS. CONCLUSIONS:The EuroSCORE and Parsonnet scoring systems are of no value in predicting periprocedural mortality risk in patients undergoing elective PCI LM. Overall, discriminative ability of the EuroSCORE, Parsonnet, and GRACE risk scores in unselected patients with ACS undergoing emergent PCI LM was good. In this group of patients, the EuroSCORE and Parsonnet scoring systems had no discriminative value in low and moderate risk patients. Only the GRACE risk score discriminated risk among intermediate and high risk patients.
