title: Risk stratification and prognostic value of grace and timi risk scores for female patients with non-st segment elevation acute coronary syndrome.
abstract: OBJECTIVE
  To investigate the value of Global Registry of Acute Coronary Events (GRACE) and Thrombolysis in Myocardial Infarction (TIMI) risk scores for risk stratification and prognosis in female patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS).
  
  
  METHODS
  Non-elderly (<65 years) and elderly (≥65 years) female patients with NSTE-ACS (totally 869 cases) were enrolled in this study. The patients were further divided into low, intermediate and high-risk groups according to their GRACE and TIMI scores. Patients were followed up for 1 year to record the mortality and incidence of major adverse cardiac events (MACE). Differences in mortality and MACE incidence between the two scoring systems were compared by the area under the ROC curve.
  
  
  RESULTS
  The area under ROC curve corresponding to the mortality and MACE incidence in any period by the GRACE scoring system was significantly larger than the TIMI scoring system in the elderly patients (P<0.05). Mortality and MACE incidence increased in parallel with the scores. Risk ratio values of Cox regression analysis based on GRACE and TIMI scores were greater than 1 (P<0.001).
  
  
  CONCLUSIONS
  Both GRACE and TIMI were adoptable in clinical risk stratification and prognosis of female patients with NSTE-ACS at different age groups. GRACE showed better accuracy than the TIMI scores.
