Introduction:

leukoglycemic index relates the number of leukocytes and blood glucose, and it correlates with the inflammation generated by the degree of the cardiac noxa.

Objective:

to determine the prognostic value of the leukoglycemic index for the intrahospital mortality rate in patients with acute myocardial infarction.

Methods:

an observational, analytical study of cases and controls in a two-year period with 155 patients. The association by means of chi-squared test was determined by the variables studied, considering as significance p<0,05. To evaluate the differentiation, the area under the curve was analyzed with confidence intervals of 95 %, calculating the Odds Ratio as well (OR).

Results:

the 56,1 % of patients were 70 years old, the mortality rate was significantly higher in these patients, and male sex prevailed with 53,5 %. Patients with glycemic values above 10mmol/l represented the minority 39,4 % (p <0,01 OR 3,4). The 49 % of these patients presented values of leukocyte count higher than 10 mmol/l (p <0,01 OR 2,5); having a leukoglycemic index above the cut-off point and 49% of the patients (p<0,01 OR 4,7). Leukoglycemic index had a higher area under the curve (0,71).

Conclusions:

leukoglycemic index is an instrument that can be useful as a predictor of intrahospital mortality in an acute myocardial infarction.
