Prognostic value of the first fasting glycemia on hospital admission in people with acute myocardial infarction. Rev Cubana Hig Epidemiol [online]. 2013, vol.51, n.2, pp. 140-154. ISSN 1561-3003.

Background: it is described that the first fasting glycemia in people hospitalized with acute myocardial infarction is associated to a bad prognosis. Objective: to determine the possible influence of hyperglycemia, particularly in the first fasting glycemia, for the prognosis of acute myocardial infarction. Methods: a transversal and descriptive study was conducted in which 157 clinical histories of patients admitted to the Coronary Care unit of the Institute of Cardiology and Cardiovascular Service in Havana Province, who were diagnosed with acute myocardial infarction, were reviewed (January 2006-December 2007). They were divided into three groups: 1) without antecedents of diabetes mellitus, with hyperglycemia on admission; 2) with previous diagnosis of diabetes mellitus on admission; 3) non-diabetics, without hyperglycemia on admission. The variables studied were: age, sex, smoking habit, alcohol intake, levels of first fasting glycemia, average values of blood glucose during hospitalization, insulin treatment (conventional or intensive), complications of acute myocardial infarction, evolution (mortal or non-mortal) and hospital stay. The values of glycemia and its treatment were correlated with cardiovascular complications, mortality and hospital stay. Results: groups 1 and 2 presented higher percentages of complications of acute myocardial infarction as well as a greater mortality in higher numbers of intra-hospital blood glucose. There was a non significant tendency of first fasting glycemia with this prognosis. Conclusions: the bad or regular intra-hospital metabolic control is associated to a bad prognosis and a greater hospital stay. There was no significant relation between first fasting glycemia and mortality after acute myocardial infarction.

Keywords : first fasting glycemia; acute myocardial infarction; diabetes mellitus; cardiovascular complications; mortality; insulin therapy.
