The clinical significance of isolated CAE has not been elucidated yet. We aimed to compare the patients with myocardial infarction (MI) due to isolated CAE with the patients without CAE.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>We retrospectively included patients who underwent coronary angiography with a diagnosis of first MI caused by isolated CAE. We excluded patients with &gt;20% stenosis in any vessel other than the lesion responsible for the MI. A second group of patients with MI without CAE was selected as the control group. The primary outcome was the composite of all-cause death and nonfatal recurrent MI occurring after index hospitalization.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      A total of 404 patients were included. Overall, 63.9% of MIs were ST-elevation MI. Almost all patients in the isolated CAE group had multivessel diffuse ectasia, with 71.3% classified as Markis I, and 26.7% as Markis II. Death or MI recurrence occurred in 54 (26.7%) patients in the isolated CAE group and 33 (16.3%) patients in the control group (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.011). Death occurred in 8 (4.0%) patients in the isolated CAE group versus 6 (3.0%) patients in the control group; recurrent MI in 46 (22.8%) versus 27 (13.4%) patients, respectively. Stent thrombosis was more common in the CAE group compared with the control group (8.9% versus 1.5%;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;0.001).
