Abstract


Background: According to the angiographic findings, 3%-8% of atherosclerotic coronary artery patients suffer from coronary artery ectasia (CAE). We conducted this study to estimate the prevalence of CAE among patients who underwent angiography and compared this group with those patients without CAE and atherosclerosis in terms of common coronary heart disease (CHD) risk factors.

Methods: This cross sectional study was conducted in Hamadan Province, western Iran, from March 2014 to March 2015. Data were collected from angiography evaluation and clinical records in Ekbatan Hospital. The patients with atherosclerosis who had CAE were compared with patients who had neither CAE nor atherosclerosis. The categorical variables were compared using chi-squared test or Fisher’s exact test.

Result: Of 2767 patients who underwent coronary angiography, 166 (6.0%) had CAE with atherosclerosis, 2357 (85.2%) had atherosclerosis without CAE, and 244 (8.8%) had normal coronary artery. Compared to normal group, CAE patient were more hypertensive and smoker. Besides, in CAE group the proportion of dyslipidemia was higher than normal subject.

Conclusion: The prevalence of CAE in Hamadan Province was in the expected level. Distribution of common CHD risk factors were most prevalent in CAE patient in comparison with normal coronary artery group.
