Are undiagnosed IGT/IFG and type 2 diabetes common in heart disease and hypertension?

Abstract

Diabetes mellitus causes significant morbidity and mortality, and up to 50% of people with diabetes may be as yet undiagnosed. Additionally impaired glucose tolerance (IGT) is known to increase vascular risk and the risk of developing diabetes.

The aim of this study was to look for IGT and/or impaired fasting glucose (IFG) and undiagnosed diabetes amongst patients with hypertension and patients with ischaemic heart disease (IHD) as part of an annual structured assessment.

In IHD patients the uptake was 83.45% with a yield of 2.47% for undiagnosed diabetes and 12.39% for IGT/IFG. In hypertensive patients the uptake was 75.84% with a yield of 2.01% for undiagnosed diabetes and 18.54% for IGT/IFG.

We concluded that looking for undiagnosed type 2 diabetes and patients with IGT/IFG in primary care may be worthwhile amongst patients with hypertension or IHD.
