Cardiovascular risk factors in type 2 diabetic patients in Bulgaria.

UNLABELLED

Type 2 diabetes mellitus is associated with an excessively high morbidity and mortality from cardiovascular disease. Macrovascular disease with its complications is the leading cause of death in Bulgaria.

AIM OF THIS STUDY

To examine cardiovascular risk factors in patients with type 2 diabetes.

MATERIAL AND METHODS

The study included 556 patients with type 2 diabetes and 575 healthy subjects. All participants filled a questionnaire on medical history, lifestyle and family history and standardised measurements were taken of some of their anthropometric parameters and blood pressure. Venous blood was drawn after an overnight fast for the examination of glucose, lipids, C-reactive protein and other cardiovascular risk factors.

RESULTS

Seventy-eight percent of the diabetic subjects had a history of coronary heart disease. The diabetics had significantly higher body mass index (27.1 +/- 4.4 kg/m2 vs. 25.0 +/- 3.8 kg/m2; mean +/- SD), waist circumference (101 +/- 10.2 vs. 87 +/- 8), systolic (131 +/- 12 mm Hg vs. 123 +/- 11) and diastolic blood pressure (85 +/- 9 mm Hg vs. 78 +/- 7), blood glucose (8.4 +/- 2.3 mmol/l vs. 5.4 +/- 0.7), total cholesterol (5.8 +/- 0.78 mmol/l vs. 4.9 +/- 1.0), triglycerides (2.18 +/- 1.02 mmol/l vs. 0.98 +/- 0.60) and C-reactive protein (5.2 +/- 3.9 vs. 3.7 +/- 3.1 mg/l) as well as significantly lower levels of HDL-cholesterol (0.96 +/- 0.28 mmol/l vs. 1.45 +/- 0.47) vs. controls.

CONCLUSIONS

Our study demonstrates that patients with type 2 diabetes in Bulgaria have significantly increased levels of cardiovascular risk factors, which could explain the excessive cardiovascular mortality of these patients.
