Pioglitazone restores endothelial function in patients with type 2 diabetes treated with insulin.

The primary aim of this study was to evaluate the effect of pioglitazone on endothelial function, as assessed by flow-mediated dilatation (FMD) nitroglycerine-induced dilatation (NID) in patients with type 2 diabetes mellitus treated with insulin. A randomized double-blind placebo-controlled trial involved 20 patients with insulin-treated type 2 diabetes. Patients received either pioglitazone 30 mg or placebo for 4 months.

Potential cardiovascular benefits of insulin sensitizers.

A multiple risk factor approach is needed in patients who have type 2 diabetes. Because many risk factors are linked with IR, treatment with insulin sensitizers has the potential to modulate these risk factors favorably. TZDs 'have many important effects beyond lowering blood glucose.

The impact of antidiabetic therapies on cardiovascular disease.

Cardiovascular disease disproportionately affects people with diabetes and is a leading cause of death. Glycemic control has so far not been conclusively shown to decrease cardiovascular events. The therapeutic agents used in treating glycemia have different effects on cardiovascular risks and, therefore, may have different effects on outcome.
