PEREZ MAYORGA, MARITZA et al. RELATIONSHIP BETWEEN GLYCATED HAEMOGLOBIN AND LEFT VENTRICULE EJECTION FRACTION IN DIABETES TYPE 2 PATIENTS ON THEIR FIRST ACUTE MYOCARDIAL INFARCTION. rev.fac.med [online]. 2014, vol.22, n.2, pp.12-19. ISSN 0121-5256.

Introduction: In the wide range of cardiovascular disease, ischemic heart disease is one of the mayor two pathologies that contribute with the greater disability and mortality rates. Type 2 Diabetes Mellitus is known to be one of the mayor risk factors associated with a worst prognosis among subjects who suffer from ischemic heart disease. Hyperglycemia augments oxidative stress in the ischemic myocardium and thus the hypoxemia and extent of necrosis. Objective: To establish if there is a relationship between glycosylated hemoglobin levels and admissions left ventricular function, measured by ejection fraction, in type 2 diabetic patients suffering from a first acute myocardial infarction. Materials and Methods: Observational study in which we characterized 36 type 2 diabetic patients suffering from a first acute myocardial infarction, hospitalized in The Hospital Militar Central. Results: Using Fischer's exact test we found that that type 2 diabetics suffering from a first acute myocardial infarction and with glycosylated hemoglobin levels above 8.5% had a tendency to present an ejection fraction below 50% (P= 0.019). Conclusions: Larger studies are needed in order to include all the possible values of glycosylated hemoglobin, so a more accurate cut off point from which a valid suspicion of deteriorated left ventricular function can be made, in the setting of type 2 diabetics with a first acute myocardial infarction.
