Effects of admission-time blood sugar on the intra-hospital death of acute myocardial infarction patients

Acute Myocardial Infarction (AMI) is one of the most important causes of death throughout the world, and many factors affect the mortality of MI. In this survey, the effects of admission-time hyperglycemia on the intra-hospital mortality rate of non-diabetic patients afflicted by MI were studied. In this analytical prospective study, 210 non-diabetic patients afflicted by MI were divided into two groups; first group was comprised of patients with admission-time blood sugar≥ 140 mg/dL and second group’s patients had blood sugar< 140 mg/dL. Data were analyzed with SPSS software, using chi-square and logistic regression tests. The mean admission-time blood sugar of MI patients was 151±63 mg/dL. Of 210 patients afflicted with MI, 125 (59.5%) had hyperglycemia (blood sugar≥140 mg/dL) and 85 (40.5%) had blood sugar< 140 mg/dL. 38 (18.1%) patients died during hospitalization that 30 (24%) persons were in the range of hyperglycemia (BS≥ 140 mg/dL) and 8 (9.4%) persons had blood sugar< 140 mg/dL (relative risk=2.5; p<0.05). This study showed that admission-time blood sugar levels are prognostic factor among patients with acute MI. Therefore, control and reducing blood sugar levels in MI patients with high blood sugar by glucose-reducing agents can lessen mortality rate of these patients.
