title: Predictive value of SYNTAX score II for clinical outcomes in octogenarian undergoing percutaneous coronary intervention.
abstract: OBJECTIVE
  To evaluate the predictive value of SYNTAX Score II (SS-II) for percutaneous coronary intervention (PCI) in octogenarian (≥ 80 years old) undergoing PCI.
  
  
  RESULTS
  Data from three consecutive years of octogenarian undergoing PCI from Ruijin Hospital (Shanghai, China) was retrospectively collected (n= 308). Follow up clinical data at one year including all cause mortality, cardiac mortality and main adverse cardiovascular and cerebrovascular events (MACCE) were collected. Patients were stratified according to tertiles of SS-II for PCI: SS-II ≤ 26 (n= 104), SS-II: 27-31 (n= 102), SS-II > 31 (n= 102). After adjustment for confounding factors, SS-II for PCI was an independent risk factors for all cause mortality (odds ratio: 2.77, 95% CI: 1.13-8.06;P= 0.04). Kaplan-Meier curves showed higher event rates for all cause mortality and cardiac mortality in higher tertile of SS-II for PCI (Log-Rank testP= 0.002 andP= 0.001, respectively). SS-II for PCI predicted one year mortality in octogenarian population undergoing PCI.
  
  
  CONCLUSIONS
  In octogenarian, SS-II which incorporated clinical variables with angiographic anatomy variable was suitable in risk stratifying and predicting clinical outcomes at one year.
