title: [Risk stratified in the National Registry of Acute Coronary Syndromes at the IMSS].
abstract: OBJECTIVE
  to identify prognostic factors in the National Registry of Acute Coronary Syndromes.
  
  
  METHODS
  patients in medical care units with acute ischemic coronary syndrome (AICS) according to the criteria of the American Heart Association/American College of Cardiology/European Society of Cardiology, considering the GRACE score (GS) were studied.
  
  
  RESULTS
  there were 2389 patients, 28.9 % women and 71.1 % men, mean age 63 ± 11.7 years; with AICS with ST-segment elevation (69.11 %) and 30.89 % with AICS without ST elevation. The average of GS was 168. A GS > 150 points in patients with AICS without ST elevation was associated with recurrent ischemia or angina (RR = 1.4, p = 0.05), left ventricular failure (RR = 3.1, p < 0.0001), stroke (RR = 2.9, p = 0.004) and arrhythmias (RR = 2.7, p < 0.0001). The patients with AICS with ST-segment elevation were associated with death (RR = 1.6, p = 0.01), reinfarction (RR = 1.7, p = 0.001), recurrent ischemia (RR = 1.2, p = 0.04), left ventricular failure (RR = 3.4, p < 0.001), stroke (RR = 3.9, p < 0.001) and arrhythmias (RR = 2.3, p < 0.001). Fibrinolytic therapy was used in 40.2 %. There was a negative correlation between GS and fibrinolytic therapy (r -0.04, p = 0.04).
  
  
  CONCLUSIONS
  the AICS with ST-segment elevation is more frequent and have a high GS.
