Abstract:
Objective To assess the value of SYNTAX score to predict major adverse cardiac and cerebrovascular events (MACCE) among patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention.Methods 190 patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention (PCI) with Cypher select drug-eluting stent were enrolled.SYNTAX score and clinical SYNTAX score were retrospectively calculated.Our clinical Endpoint focused on MACCE,a composite of death,nonfatal myocardial infarction (MI),stroke and repeat revascularization.The value of SYNTAX score and clinical SYNTAX score to predict MACCE were studied respectively.Results 29 patients were observed to suffer from MACCE,accouting 18.5％ of the overall 190 patients.MACCE rates of low ( ≤ 20.5 ),intermediate ( 21.0-31.0 ),and high ( ≥ 31.5 ) tertiles according to SYNTAX score were 9.1％,16.2％ and 30.9％ respectively.Both univariate and multivariate analysis showed that SYNTAX score was the independent predictor of MACCE.MACCE rates of low ( ≤ 19.5 ),intermediate( 19.6-29.1 ),and high( ≥29.2) tertiles according to clinical SYNTAX score were 14.9％,9.8％ and 30.6％ respectively.Both univariate and multivariate analysis showed that clinical SYNTAX score was the independent predictor of MACCE.ROC analysis showed both SYNTAX score ( AUC =0.667,P =0.004) and clinical SYNTAX score ( AUC =0.636,P =0.020) had predictive value of MACCE.Clinical SYNTAX score failed to show better predictive ability than the SYNTAX score.Conclusions Both SYNTAX score and clinical SYNTAX score could be independent risk predictors for MACCE among patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention.Clinical SYNTAX score failed to show better predictive ability than the SYNTAX score in this group of patients.
