Accuracy of cardiogoniometry in the diagnosis of ischemic heart disease in diabetic patients

Ischemic heart disease (IHD) is the leading cause of death and disability globally, and type 2 diabetes is a risk factor for it. Cardiogoniometry is a non-invasive method developed to diagnose IHD, but its accuracy in diagnosing IHD in diabetic patients has not been studied so far. Therefore, this study evaluated the accuracy of cardiogoniometry in diagnosing IHD in diabetic patients in Ahvaz, Iran.

In this descriptive cross-sectional study, 142 diabetic patients with suspected IHD who were candidates for primary coronary angiography were included. Cardiogoniometry was performed in diabetic patients with chest pain before diagnostic angiography and the results were compared to angiography. Finally, its sensitivity and specificity were calculated.

Mean age of participants was 59.8 years. A comparison of cardiogoniometry results with angiography in diabetic patients showed a sensitivity and specificity of 64.48% (95% CI 58.41-77.07) and 78% (95% CI 44.87-81.28) for cardiogoniometry in IHD diagnosis, respectively. The sensitivity and specificity of cardiogoniometry were 63% and 76% in women and 75% and 62% in men, respectively.

Cardiogoniometry has relatively high sensitivity and specificity in diagnosing IHD in diabetic patients and can be regarded as a useful screening tool for IHD diagnosis in these patients.
