CORONARY ARTERY DISEASE ON CT-CORONARY ANGIOGRAM – COMPARISON BETWEEN DIABETIC AND NON-DIABETIC POPULATION

Abstract

Objective: To evaluate the CT coronary angiograms of patients presenting with symptoms of coronary artery disease (CAD) as well as to compare the results between the diabetics and non-diabetics.

Methodology: This descriptive cross-sectional study was carried out in Cardiology department of Chaudhary Pervaiz Elahi Institute of Cardiology, Multan. One hundred and fifty nine patients with history of symptoms of CAD and no previous history of myocardial infarction or revascularization were included in study. The conventional risk factors were noted and 64 slice multi detector CT coronary angiogram was done on all patients. Total calcium score and number of segments with disease, obstructive disease and non-obstructive disease were noted. Results were compared among diabetic and non-diabetic patients.

Results: Mean age of the patients was 50.54±7.90 years. Out of 159 patients 118(74.2%) were males and 41 (25.8%) were females. Diabetic patients were 101(63.5%), 64 (40.3%) were hypertensive, 39(24.5%) were smokers, 24.5% (n=39) had positive family history, 18.2% (n=29) were obese and 13.8% (n=22) had dyslipidemia. There was no coronary artery disease in 40 (25.2%) patients while 91 (57.2%) patients had obstructive and 28 (17.6%) patients had non-obstructive disease. 83. 1% diabetics had obstructive CAD and 12.0% of non diabetic patients had obstructive CAD. Mean number of obstructive segments in diabetic patients are 2.36±1.23.

Conclusion: CAD was more prevalent in diabetic patients and CAD is easily predicted by non-invasive technique of CT coronary angiography.
