Prevalence of Coronary Artery Ectasia among Egyptian Patients with Coronary Artery Disease, retrospective analysis; Mansoura University Cardiology Department

Abstract

Background: Coronary artery ectasia (CAE) is mainly diagnosed with coronary angiography and is characterized by abnormal dilatation of the coronary arteries by more than 1.5 times the adjacent normal vessels. This study aimed to evaluate the CAE prevalence among Egyptian patients with coronary artery disease (CAD). Results: The prevalence of ectasia was 6.66%. There was a significant increase in the prevalence of CAE among males (9.05%) than females (2.71%) (P < 0.001). Additionally, a significant increase was observed in CAE prevalence in the presence of any positive RF (7.11%) than in the absence of any RF (2.22%) (P <0.001). Furthermore, the prevalence of CAE was significantly higher among smokers than nonsmokers (11.11% vs. 5.65%, respectively, P < 0.001), patients with atherosclerosis than cases with coronary lumen stenosis (12.48% vs. 5.94%, respectively, P < 0.001). The prevalence was low in cases with normal angiographic appearance (0.70%, P < 0.001).
Conclusions: The prevalence of CAE among patients admitted for diagnostic catheterization is similar to that reported in other Egyptian studies but higher than worldwide ones. It is predominant in males and more prevalent in smokers. Also, there
is an increase in ectasia prevalence in patients with atherosclerosis.
