[Coronary heart disease and insulin concentration in type II diabetic patients--results of a diabetes intervention study].
There is experimental, clinical and epidemiological evidence that elevated insulin levels are associated with development of atherosclerosis. Early results came from studies in non-diabetics, but the situation with respect to diabetes is more complex and not so clear. The Diabetes Intervention Study is a population-based follow-up study in newly detected type II diabetics (30- to 55-yr-old). After 5 years 431 men and 320 women received a complex check up with oral glucose tolerance tests and measurements of plasma insulin and glucose levels, fasting and 2h post-load. Regarding the metabolic parameters, the fasting and postprandial insulin levels were higher among the patients having coronary heart disease (15% of men, 36% of women), as compared to patients without this disease. In multivariate analysis sex, age, antihypertensive treatment, blood pressure, body mass index, and fasting insulin levels were independently associated with the prevalence of coronary heart disease in patients with non-insulin dependent diabetes mellitus (NIDDM) treated with diet and/or oral antidiabetics. Body mass index and triglycerides were the only variables that independently correlated to insulin: fasting insulin = 0.4 (body mass index) + 0.1 (triglycerides) - 4,2. In future prospective studies of diabetics relating insulin concentrations to the development of vascular disease are of particular interest and necessity. Because hyperinsulinemia may contribute to accelerated atherosclerosis in NIDDM-patients, the aim of the treatment of type II-diabetes should be to correct hyperglycemia without aggravating insulin levels and other cardiovascular risk factors.
