Abstract:
Objective: Residual SYNTAX score (rSS) can be used as the independent predictor for clinical prognosis and the tool for quantifying incomplete revascularization (IR) in coronary artery disease (CAD) patients with percutaneous coronary intervention (PCI). Our work assessed the prognostic value of rSS on large-scale PCI patients in China. Methods: A total of 10 724 CAD patients undergoing PCI in our hospital in 2013 were studied; 381 patients with previous CABG and hybrid procedure were excluded, 10 343 patients were finally enrolled. Baseline SYNTAX score (bSS) and rSS were calculated before and after PCI. Complete revascularization (CR) was defined by rSS=0 and IR was defined by rSS≥1. The patients were followed-up for 30 months. Clinical endpoint events included MACE, a composite event of all-cause death, myocardial infarction (MI) and revascularization; all-cause death, cardiac death, MI, all-cause death/MI and revascularization.Results: There were 5 050/10 343 (48.8%) patients having CR and 5 293 having IR including 1 908 (18.4%) patients with 1≤rSS≤4, 1 777 (17.2%) with 49. Patients with the higher rSS had more clinical comorbidity and more complicated coronary lesions. Compared with CR patients, IR patients had the higher incidences of 30-month clinical endpoint events. As rSS increasing, the incidence of MACE was elevating accordingly. Multivariate regression analysis indicated that rSS was the independent predictor for MACE and all other endpoints occurrence. Conclusion: IR patients especially those with rSS>9 had the higher incidence of adverse clinical outcomes. rSS has been a good tool for quantifying revascularization and assessing prognosis in PCI patients in China.
