title: [Usefulness of the residual SYNTAX score to predict long term outcome in acute coronary syndrome patients underwent percutaneous coronary intervention].
abstract: Objective:To quantify the extent and complexity of residual coronary stenosis following PCI by the residual SYNTAX score, and to evaluate its impact on adverse ischemic outcomes in acute coronary syndrome(ACS) patients.Methods:From January 2013 to December 2013, a total of 1 414 consecutive moderate- and high-risk ACS patients who underwent any PCI with multi-vessel coronary artery disease were evaluated.Patients were stratified by rSS quartiles and their outcomes were compared.Results:The rSS was 4.8±6.7. 591 patients (41.8%) had rSS=0(CR), 233 patients (16.5%) had rSS>0 but ≤ 3, 296 patients (20.9%) had rSS>3 but ≤8 and 294 patients (20.8%) had rSS>8.Clinical risk factors were more frequent in patients with incomplete revascularization(IR) compared with complete revascularization(CR). The 2-year rates of all-caused death(1.2% vs 0.4%, 2.0%, 4.4%,P=0.003), cardiac death, revascularization and MACCE were significantly higher in high rSS group, compared to other groups.By multivariable analysis, rSS was a strong independent predictor of ischemic outcomes at 2-year, including all-cause mortality (HR=1.05, 95%CI1.01-1.09,P=0.019), cardiac death, revascularization and MACCE.Conclusions:The rSS is a strong independent predictor of all-caused death, cardiac death, revascularization and MACCE and has moderated predictive ability for those ischemic outcomes.
