We investigated the prevalence, distribution, risk factors, and prognosis of coronary artery ectasia (CAE) in patients undergoing coronary angiography for suspected coronary artery disease (CAD).

Of 4,119 patients undergoing elective coronary angiography between 2003 and 2005, 173 patients (139 males, 34 females; mean age 61±11 years) had CAE, with a prevalence of 4.2%. Distribution of CAE was made according to the classification of Markis et al. The results were compared with those of 145 control patients (115 males, 30 males; mean age 61±10 years) who had CAD but not CAE. Following coronary angiography, treatment was designed as aortocoronary bypass (n=3), percutaneous coronary intervention (n=36), and medical therapy (n=98). The mean follow-up was 34.2±2.5 months.

Among CAE patients, there was a marked male preponderance with 80.3%. Coronary ectasia was isolated in 46 patients (26.6%) and was associated with significant coronary artery stenoses in 127 patients (73.4%). The only significant difference with the control group with respect to baseline features was the higher frequency of hypertension in the CAE group (p=0.002). Coronary ectasia involved a single vessel in 67.1%, two vessels in 24.9%, and three vessels in 8.1%, with the right coronary artery being the most common localization (50.9%). The diameters of ectatic coronary arteries ranged from 3.2 mm to 9.7 mm (mean 5.6 mm). According to the classification of Markis et al., the majority of patients (64.2%) had type IV ectasia. In multiple regression analysis, hypertension was independently associated with CAE (OR: 0.378; 95% CI: 0.211-0.678; p=0.001). Mortality occurred in nine patients (5.2%). The annual mortality rates were 1.5%, 2.1%, and 2.9% with medical therapy, percutaneous coronary intervention, and aortocoronary bypass, respectively.

Our findings suggest that further prospective studies focus on the dependent relationship between hypertension and CAE, and on marked coexistence of CAD and CAE.
