title: [Hyperglycemia at admission and outcome in elderly patients with acute ST segment elevation myocardial infarction underwent primary percutaneous coronary intervention].
abstract: OBJECTIVE
  To investigate the association between hyperglycemia and outcome in elderly patients with acute ST segment elevation myocardial infarction (STEMI) underwent primary percutaneous coronary intervention (PCI).
  
  
  METHODS
  This retrospective analysis was performed on 284 elderly patients (age > or = 60 years) with acute STEMI underwent primary PCI between January 2000 to April 2004 in our department. Patients were divided into 3 groups according to the level of blood glucose on admission: group A, < 7.8 mmol/L; group B, 7.8 - 10.9 mmol/L; group C, > or = 11.0 mmol/L.
  
  
  RESULTS
  (1) The proportion of female in group B and group C was greater than that of group A (33.3% vs. 26.5%, P < 0.01; 40.2% vs. 26.5%, P < 0.01). The hospital stay time of group B and group C was significantly longer than that of group A (16.0 days vs. 13.9 days, P < 0.05; 16.6 days vs. 13.9 days, P < 0.05). There were more patients with history of hypertension in group C than that in group A (72.1% vs. 54.9%, P < 0.01). (2) After PCI, the proportion of patients with TIMI myocardial perfusion grade (TMPG) 0-1 in group B and C was greater than that of group A (22.6% vs. 13.3%, P < 0.05; 34.1% vs. 13.3%, P < 0.05). The proportion of patients with TMPG 3 in group B and C was less than that in group A (74.3% vs. 84.4%, P < 0.05; 57.6% vs. 84.4%, P < 0.05). The complication rate of PCI was significantly higher in group C than in group A (42.5% vs. 20.6%, P < 0.01) and group B (42.5% vs. 26.6%, P < 0.01). IABP use was significantly more in group C than that in group A (19.5% vs. 4.9%, P < 0.01) and group B (19.5% vs. 6.4%, P < 0.01). (3) There were more patients with grade of Killip class > or = 2 in group C than that in group A (44.8% vs. 23.5%, P < 0.01) and group B (44.8% vs. 27.7%, P < 0.01). The in-hospital mortality rate (8.0% vs. 1.1%, P < 0.05) and one-year mortality rate (18.7% vs. 3.4%, P < 0.05) of group C were significantly higher than those in group A.
  
  
  CONCLUSIONS
  Hyperglycemia at admission was associated with poor tissue perfusion, cardiac function and prognosis in elderly patients with acute STEMI underwent primary PCI.
