Abstract
Diabetes is known to be a major cardiovascular risk factor associated with significantly increased morbidity and mortality and particularly increased risk of major cardiac events especially myocardial infarction as a manifestation of highly incident coronary artery disease (CAD).This can lead to decreased life expectation and life quality. Major cause for myocardial infarction is plaque rupture. Prevalence of obstructive and non-obstructive plaques is increased in diabetic patients.
Background and Objectives
The prevalence of coronary heart disease in diabetic patients compared to non- diabetics and evaluating the composition of the plaque in diseased individuals in both groups by usage of multislice computed tomography (MSCT) angiography .
Subjects and Methods
A total of 80 consecutive MSCT angiography examinations were performed between August 2017 and June 2018. Of these, the patients were evaluated for the presence and type of atherosclerotic plaque and severity of luminal narrowing.
Results
Eighty (40 in the diabetic group and 40 in the non-diabetic group) patients underwent MSCT angiography with DM prevalence of 0.212 (95% Cl for AOR 0.056 -1.896). Among them, 20 patients (50 %) in the diabetic group and 14 patients (35 %) in the non-diabetic group had +ve coronary heart disease, 33.3 % had significant and moderately significant coronary narrowing on diabetic group and 31.3 % in non-diabetic group on MSCT angiography. Diabetic patients had more soft plaque compared with non-diabetic patients.
Conclusion
DM is not an independent factor for the disease occurrence in coronary artery disease but is a dependent factor in the association of other risk factors such as smoking ,hypertension and dyslipidemia.
