Glycated Hemoglobin in the Pre and Diabetes Ranges as Related to Lipid Cardiovascular Risk

The concomitance of diabetes metabolic markers, as Glycated Hemoglobin and blood glucose, together with lipid changes; Cholesterol and fractions and Triglycerides, occurs very frequently but not always in the same pairs of markers, being its peculiarities important factors for the estimation of the cardiovascular risk. Not only has the association of high glucose levels and high triglycerides pointed to an augmented risk. The study of the correlations of the parameter Glycated Hemoglobin with all the values of the lipid profile may help gain a broader insight as to the associated risks. A database of 548 individuals with concomitant results of HbA1C, triglycerides, CT and HDL-c were applied statistical tests of ANOVA and Tukey. Most of the 546 individuals tested for glycated hemoglobin (HbA1C) and lipid profile had HbA1C levels within normal range (49.8%), 15.4% were classified as prediabetic, and 34.8% had HbA1C levels above 6.4% (diabetics). The overall mean HbA1C observed was 6.3%, and triglycerides was 236.8 mg/dL. Data from HbA1C-lipid profile comparations are not superimposed, as expected, to the combinations of fasting glucose and triglycerides. In not accompanying lipids concomitantly with HbA1C, the correct assessment of the overall risk calculation for atherosclerosis can be omitted. In conclusion, HbA1C levels should be added to the lipid profile for a more accurate estimation of the cardiovascular risk.
