Predictors of Coronary Artery Disease in Patients with Type 2 Diabetes Mellitus

Introduction: Abundant evidence shows that patients with type 2 diabetes are at high risk for several cardiovascular disorders: coronary heart disease, stroke, peripheral arterial disease, cardiomyopathy, and congestive heart failure.
Aim: This study aimed to identify predictors of occurrence of coronary artery disease (CAD) in patients with type 2 diabetes mellitus.
Methods: This cross-sectional descriptive study was conducted on 100 patients with type 2 diabetes mellitus referred for coronary angiography with normal systolic function, no segmental wall motion abnormality and suspected CAD.
Results: It was found that 12% of cases had normal coronaries and 88% of cases had coronary artery disease. Only male sex, total cholesterol ≥ 150 mg/dL, HbA1c ≥ 7.0 and BMI ≥ 25.0 kg/m² were significant risk factors that increase the probability of having CA abnormality.
Conclusion: The main predictors of presenting the disease were male sex, total cholesterol ≥ 150 mg/dL, HbA1c ≥ 7.0 and BMI ≥ 25.0 kg/m². The high prevalence of obesity highlights the need to improve measures to prevent cardiovascular disease in this population.
