Abstract

Coronary artery ectasia is known as the cause of chest pain and dyspnea. Because of its variable presentations according to the genetic and environmental differences, we studied patients with pure coronary artery ectasia in north-west of Iran. Materials & Methods: Exclusion criteria were established ectasia in one or more coronary arteries without any significant coronary artery stenosis defined as stenosis > 70%. Coronary artery angiography and demographic data of patients were evaluated. Results: The mean age of patients according to the type of ectasia were 54.57±8.65 in type 1, 59.95±9.62 in type 2, 58.91±12.33 in type 3, and 57.46±10.74 in type 4. Type 3 ectasia was the most common type of ectasia (30.7%). Type 1 ectasia was more common in men and type 3 ectasia was more common in women (p=0.04). There wasn’t any significant association between the type of ectasia and the prevalence of dyspnea or chest pain. Coronary artery ectasia was frequently observed in the left anterior descending artery (LAD). Conclusion: The prevalence of coronary ectasia according to its types is different between men and women. There was no association between the extent of ectasia according to Markis classification and the prevalence of dyspnea and chest pain.
