title: Predictors of long-term survival in acute coronary syndrome patients with left ventricular dysfunction after percutaneous coronary intervention.
abstract: OBJECTIVE
  Predictive factors of mortality in acute coronary syndrome (ACS) patients with left ventricular dysfunction were analyzed during 5-year clinical follow-up after percutaneous coronary intervention (PCI).
  
  
  METHODS
  A total of 329 ACS consecutive patients (64.6±11.3 years, 227 males) who underwent PCI from January 2001 to March 2006 were followed for 5 years. All patients had lower than 40% of left ventricular ejection fraction (LVEF). Patients were divided into Group I (survived longer than 5-years: n=130, 101 males) and Group II (survived shorter than 5 years: n=199, 126 males).
  
  
  RESULTS
  The cumulative survival rate was 88.0% at 1 month, 78.0% at 6 months, 75.0% at 1 year, 67.0% at 2 years, 62.0% at 3 years, 57.0% at 4 years and 40% at 5-years. Group II was older (61.6±11.2 years vs. 66.4±11.4 years, p<0.001), and showed higher prevalence of female gender (28.4% vs. 36.7%, p=0.006) and lower LVEF (35.3±5.2 vs. 33.6±5.6) than Group I. The independent predictors for mortality were LVEF <30% {odds ratio (OR)=1.793, 95% confidence interval (CI): 1.234-2.452, p=0.002}, serum creatinine >3.0 mg/dL (OR=2.455, 95% CI: 1.306-4.614, p=0.005), older than 65 years (OR=1.594, 95% CI: 1.152-2.206, p=0.005), and female gender (OR=1.524, 95% CI: 1.090-2.130, p=0.014).
  
  
  CONCLUSIONS
  Five-year survival rate was 40% in ACS patients with left ventricular dysfunction, and the predictors for mortality were low LVEF, high serum creatinine, old age, and female gender.
