Editorial: Coronary Artery Ectasia in Patients With ST-Segment Elevation Myocardial Infarction: Angiographic and Long-Term Clinical Outcomes
Coronary artery ectasia (CAE) is defined as coronary artery dilatation of >1.5-fold the diameter of adjacent normal coronary segments and constitutes an uncommon finding detected incidentally in up to 5% of patients undergoing coronary angiography . Although the terms CAE and coronary artery aneurysm are frequently used interchangeably, the term CAE should be used for more diffuse aneurysmal lesions and the term coronary artery aneurysms for more segmental lesions (dilation ≥1.5 times the adjacent normal segment) .
