Predictive Value of Fasting Blood Sugar for Non-Diabetic Individuals Suffering from Severe Coronary Disease

This study was designed to determine if high fasting blood sugar (FBS) level is an independent predictor of severe coronary lesions in patients with coronary artery disease (CAD). In this study, 34 patients who had symptoms of chest discomfort and who underwent coronary angiography were enrolled. FBS was determined from blood samples and the extent of coronary artery lesions was analyzed according to Gensini score. We examined the relationships among diabetes, FBS and coronary artery severity. Diabetes and FBS were significantly and positively related to Gensini score. Diabetes, but not FBs, was independently correlated with the occurrence of a Gensini score greater than41. However, FBS was significantly associated with Gensini score greater than41 in non-diabetic patients. Hyperglycemia is an independent predictor of severe CAD in non-diabetic patients. Clinicians should be aware of this and should carry out appropriate early interventions.
