ABSTRACT
Objective To evaluate the predictive value of admission blood glucose level for the mortality within 30-day and major adverse cardiac events(MACE) rate in patients with ST-segment elevation acute myocardial infarction (STEMI). Methods An observational analysis of 7446 Chinese STEMI patients from a global randomized controlled trials of cases recruited within 12 hours of symptom onset was carried out. According to the levels of admission glucose (hyperglycemia was defined as admission glucose>10 mmol/L) and known diagnosis of diabetes mellitus (DM) ,these patients were divided into four groups, Ⅰno DM and normal glucose group (control group) ; Ⅱ DM but normal glucose group; Ⅲ no DM and hyperglycemia group; and Ⅳ DM and hyperglycemia group. Results Admission hyperglycemia was associated with a significantly higher 30-day mortality rate (group Ⅲ 17. 1% vs group I 8.6%, group Ⅳ 18.6% vs group Ⅰ 8. 6%, P<0.001) and also an increased incidence of MACE (group Ⅲ36. 3% vs group Ⅰ 21.6%, group Ⅳ 38. 8% vs group Ⅰ 21.6%, P<0.001). However, DM without admission hyperglycemia did not increase the 30-day mortality (group Ⅱ 11.6% vs group Ⅰ 8. 6%, P = 0.096). Multivariate logistic regression analysis showed that compared with group Ⅰ patients, group Ⅲ and group Ⅳ had a risk of death of 1.51 fold(OR 1.51,95% CI 1.22-1.87,P<0.001) and 1.83 fold(OR 1.83,95% CI 1.40-2. 39, P<0.001) respectively; hyperglycemia was an independent predictor of 30-day mortality and an increase of 1 mmol/L in glucose level was associated with a 5% increase of mortality risk (OR 1.05,95% CI 1.04-1.07,P<0.001), but DM without hyperglycemia was not so (OR 1.11,95% CI 0. 87-1.42, P =0. 412). Conclusions The rates of 30-day mortality and cardiovascular events are significantly higher in STEMI patients with acute hyperglycemia than in patients without. Hyperglycemia on admission is an independent risk factor for the short-term outcome of STEMI, but diabetes mellitus without hyperglycemia isv not associated with the short-term mortality.
