Coronary angiographic findings among diabetic and non-diabetic patients


objectives: Atherosclerotic coronary artery disease (CAD) is a major cause of death all over the world. Among patients with CAD there are many of them having diabetes mellitus which is regarded as a major additive risk factor. Diabetic patients who developed CAD carry high morbidity and mortality rates.
The objective of this study was to analyze the coronary angiographic outcome of patients with type two diabetes mellitus suspected to have coronary artery disease and comparing these results with non-diabetic patients.
Methods: Patients referred to Mosul Cardiac Catheterization Unit of Ibn-Sena Teaching Hospital for coronary angiography were serially included until obtaining a total of 75 diabetic and 75 non-diabetic patients with predicted coronary artery disease and with different ischemic heart disease risk factors including obesity, smoking, hypertension and dyslipidemia. All of them underwent coronary angiography.
Result: Diabetic patients showed more significant stenotic lesions. Moreover the lesions in the coronary artery were more diffuse with higher incidence of multivessel involvement in comparison to non-diabetic patients. Also diabetic patients show increasing incidence of the left main stem artery involvement which carry very high mortality rate.
Conclusion: Diabetes mellitus is an independent risk factor for coronary artery disease associated with more advanced, serious and extensive obstructive atherosclerotic lesions in the coronary arteries.
