BACKGROUND: Coronary artery ectasia (CAE) influences procedural outcomes in the context of ST-elevation myocardial infarction (STEMI); however, its relationship with atherosclerotic coronary artery disease (ACAD) remains unclear.
AIMS: This study aimed to compare clinical and procedural characteristics, as well as outcomes, in patients with STEMI and CAE, with or without coexisting ACAD.
METHODS: Overall, 148 patients with STEMI and ectatic infarct-related artery who underwent primary percutaneous intervention were included from 2003 to 2021. These patients were stratified based on the presence of atherosclerotic disease into two groups: patients with STEMI and isolated CAE (n = 74) and those with CAE and coexisting ACAD (n = 74).
RESULTS: Compared with patients in the isolated CAE group, those in the CAE and coexisting ACAD groups were older (65 vs. 58.4 year, p = 0.002), with no significant differences in cardiovascular risk factors or initial clinical presentation. Coronary angioplasty was performed more frequently in the CAE with coexisting ACAD group (90.5% vs. 63.7%, p < 0.001), with a higher stenting rate (73.0% vs. 48.6%, p = 0.004) and a trend toward less frequent distal embolization (35.3% vs. 52.9%, p = 0.057). No significant differences were observed between the two groups in troponin or CPK levels, nor in left ventricular ejection fraction at hospital discharge (48 ± 10% vs. 49 ± 10%, p = 0.569). At the 3-year follow-up, the overall MACE-free rate was 85.1%, with no significant difference between the groups (83.8% vs. 78.4%, p = 0.487).
CONCLUSION: Patients with STEMI and ectatic related infarct-related artery who underwent primary PCI demonstrated distinct periprocedural characteristics depending on the presence or absence of coronary atherosclerosis. Further research is needed to determine optimal therapeutic management at discharge.
