Introduction: Angiotensin converting enzyme (ACE) is an exopeptidase that converts Angiotensin I to Angiotensin
II. Angiotensin II is a potent vasoconstrictor and releases aldosterone, and have a critical role in hypertension. In this
study, ACE insertion / deletion (I/D) polymorphism and ACE activity was determined in patients with coronary artery
disease (CAD) and normal subjects. The correlation of these parameters with important CAD risk factors were also
evaluated.
Methods: 204 subjects were assigned to patients and normal groups based on their angiography results. Serum ACE
activities were assayed by HPLC and I/D polymorphism were analyzed by PCR method. Important risk factors such as
diabetes mellitus, hypertension, lipid profiles, ejection fraction, smoking and opium consumption were also recorded.
Results: CAD was higher in DD genotype subjects (OR= 2.45 CI= 1.05-5.73), and ACE activity was about twice in
DD compared to II genotypes. ACE activity was higher in hypertensives and diabetics in CAD group (p<0.001), but in
the normal group it did not have any correlation with these risk factors. The rate of opium use was higher in ID and DD
subjects.
Conclusion: DD genotype is a risk factor for CAD and ACE activity is higher in this genotype. However, there is
not any correlation between ACE activity and CAD.
