Overview

Patients with less severe glycated haemoglobin (HbA1c) targets may find it difficult to achieve the target values of lipid parameters treatment at high cardiovascular risk. We have been monitoring the correlation between levels of triglycerides (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) with glycosylated haemoglobin (HbA1c) by IFCC method (method of testing according to the International Federation of Clinical Chemistry and Laboratory Medicine) and by DCCT method (Diabetes Control and Complication Trial) as well as body mass index (BMI) at the time of diagnosis of the disease, that could help identify patients with an increased risk of cardiovascular disease. In the cohort study we were monitoring outpatients with newly diagnosed type 2 diabetes mellitus during a 5 year period. Patients (117 men, 83 women), aged from 30 to 92 years were conducted sampling blood glucose, HbA1c (IFCC/DCCT), HDL, LDL, TG. At baseline, the patients’ height, weight, waist circumference, calculated BMI and blood pressure were measured. Waist circumference was measured in the horizontal plane in the middle of the distance between the upper edge of the iliac crest and the lower edge of the last rib in the breath. Our study did not exclude patients taking statin or fibrate. The high HbA1c values increased the risk of elevating LDL-cholesterol levels and TAG levels in the whole group (p = 0.012) and (p = 0.017), and the high BMI values increased the risk of lowering HDL-cholesterol levels in the female population (p = 0.010). The results of our study stratify the increased risk of atherogenicity in these groups. HbA1c is a direct marker of elevated LDL and TAG, and indirect marker for coronary artery disease risk assessment.
