OBJECTIVE: Several studies to date have examined whether admission levels of hemoglobin A1c (HbA1c) correlate with short-term and long-term outcomes in patients with acute myocardial infarction treated with primary percutaneous coronary intervention (PCI). However, the results have been ambiguous. We speculated that admission levels of HbA1c correlate with short-term outcomes of patients with ST-elevation myocardial infarction (STEMI) undergoing primary PCI. METHODS: In this observational multicenter study, 608 patients with STEMI who underwent primary PCI between June 2001 and July 2004 were enrolled. Blood samples were collected upon admission to hospital for HbA1c measurement. Follow-up was carried out at 7 and 30 days after hospital admission. According to the new American Diabetes Association criteria, patients were stratified into three groups: I, HbA1c 5.6% or less (n=262); II, HbA1c 5.7-6.4% (n=182); and III, HbA1c at least 6.5% (n=164). The primary outcomes were all-cause mortality and major adverse cardiac events at follow-up. RESULTS: The 7-day mortality was similar (P=0.179) between groups I (1.9%), II (2.2%), and III (0.0%); the 30-day mortality was also similar (P=0.241) between groups I (3.8%), II (2.2%), and III (1.2%). MACE at the 7- day and 30-day follow-up were not significantly different between the three groups either (P>0.05). Rates of target vessel revascularization and rehospitalization, and MACE-free survival curves, at the 30-day follow-up were also similar among the three groups. After adjusting the baseline characteristics, HbA1c was not an independent predictor of short-term outcomes (hazards ratio: 0.431; 95% confidence interval: 0.175-1.061, P=0.067). CONCLUSION: Admission levels of HbA1c are not an independent prognostic marker for short-term outcomes in STEMI patients treated with primary PCI.
