Abstract
Background: Localized or diffuse dilatation of the coronary arteries (coronary ectasia) is a well-known, albeit rare, angiographic We aimed to determine its incidence, baseline characteristics, and prognosis in patients in the Czech Republic. Of the 6,997 patients, only 52 (0.7%) were assigned to the coronary artery ectasia group.
The right coronary artery was the most common vessel affected by coronary artery ectasia. A comparison of traditional risk factors for coronary artery disease and mortality between patients with isolated coronary artery ectasia and those with ectasia coexisting with stenosed coronary artery disease revealed no statistically significant differences in its incidence.
The incidence of coronary artery ectasia in our study was 0.7%. The majority of patients were males; they had hypertension and dyslipidemia, and a history of cigarette smoking.
The most affected vessel was the right coronary artery. Isolated coronary ectasia occurred in 15.4%, no death in this group was noted.
