Accuracy of Cardiogoniometry in the Diagnosis of Ischemic Heart Disease among Diabetic Patients

Abstract

Background and Objectives Ischemic heart disease (IHD) is the leading cause of death and disability globally, and type 2 diabetes is a risk factor of this disease. Cardiogoniometry is a non-invasive method developed to diagnose IHD, but its accuracy in diagnosing IHD in diabetic patients has not yet been studied. Therefore, this study evaluated the accuracy of cardiogoniometry in diagnosing IHD in diabetic patients in Ahvaz, Iran. Subjects and Methods This descriptive cross-sectional study included 142 diabetic patients with suspected IHD who were candidates for primary coronary angiography. Cardiogoniometry was performed for diabetic patients with chest pain before diagnostic angiography, and the results were compared to those of angiography. Finally, its sensitivity and specificity were calculated. Results The mean age of the participants was 59.8 years. A comparison of the results of cardiogoniometry and 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. Conclusion 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.
