Hyperinsulinemia is an independent risk factor for ischemic heart disease. A study of 2103 men without a history of ischemic heart disease found that those who later developed ischemic heart disease had significantly higher fasting insulin levels compared to controls. Logistic regression analysis showed that higher insulin levels were associated with an increased risk of ischemic heart disease, even after adjusting for other risk factors such as blood pressure, medication use, and family history. Further adjustments for lipoprotein concentrations did not significantly reduce this association, suggesting that hyperinsulinemia may be an independent predictor of ischemic heart disease. The study also found that hyperinsulinemia was not independently associated with ischemic heart disease unless accompanied by elevated triglyceride levels. The results indicate that hyperinsulinemia may contribute to ischemic heart disease through mechanisms other than dyslipidemia, such as impaired fibrinolysis and increased susceptibility to thrombosis. The study highlights the importance of insulin sensitivity and low plasma insulin concentrations in preventing type II diabetes and heart disease. The findings support the notion that hyperinsulinemia may serve as a marker for other metabolic and hemostatic disturbances associated with increased risk of ischemic heart disease. The study also emphasizes the need for standardized insulin measurements and further research to clarify the relationship between hyperinsulinemia and ischemic heart disease.Hyperinsulinemia is an independent risk factor for ischemic heart disease.
