Coronary Artery Disease (CAD) incidence varies according to certain risks; patients with pre-existing cardiovascular heart disease who later develop diabetes mellitus (DM) have the greatest risk, and non-diabetic patients with CAD, diabetic patients without CAD, and patients with metabolic syndrome (MetS) the next three high risk categories. Insulin resistance, a major feature in both DM and MetS probably causes atherogenic dyslipidaemia.

Objectives: (1) to determine the prevalence of MetS and DM in the study population, (2) to determine the prevalence of Coronary Artery Disease (CAD) in DM with MetS (DM+/MetS+), in DM alone (DM+/MetS-), MetS alone (Mets+/DM-) and in ‘normal’ group (DM-/MetS-), and (3) to determine the prevalence of MetS in DM patients.

Results: 62.1% of the study population had MetS, 44.7% had DM, 83.6% had both MetS and DM. 18.6% had CAD. CAD was seen in 25.2% of DM+/MetS+, 19.1% of MetS+/DM-, 14.3% of DM+/MetS-, and 11.6% of MetS-/DMpatients. DM+/MetS+ group had the highest association with CAD OR= 2.19, CI (1.43-3.35), DM-/MetS- group the lowest association OR=0.45, CI (0.27-0.73), and DM+/MetS- (OR=0.69, CI (0.28-1.73) and MetS+/DM- (OR=0.94, CI (0.57- 1.58) had no significant association with CAD.

Conclusion: Only DM+/MetS+ patients had a high risk of developing CAD. Risk of CAD in patients with MetS+/ DM- and DM+/MetS- was not statistically significant in multivariate analysis, while the group with neither, MS-/DM-, had the lowest risk of developing CAD.
