Abstract

Background/Objectives: Coronary artery ectasia (CAE) presents challenges, specifically in the context of percutaneous coronary intervention (PCI), and has been associated with adverse events, particularly in the setting of acute myocardial infarction (AMI). The objective of the present study was to assess whether CAE is associated with increased occurrence of major adverse cardiovascular events (MACEs) in patients with AMI. Methods: A systematic review and meta-analysis of observational studies were conducted. We systematically searched MEDLINE via PubMed, Scopus, the Cochrane Library (CENTRAL), ClinicalTrials.gov, and reference lists to identify eligible studies. Baseline characteristics, comorbidities, angiographic data, and rates of MACEs and their individual components (all-cause or cardiovascular mortality, repeat AMI, repeat revascularization, stroke, and heart failure) have been extracted. The results were synthesized as odds ratios (ORs) using random-effects models. Results: Ten studies and 13,908 patients were included. CAE was found to be predictive of higher odds of MACEs [OR: 2.12, 95% CI: 1.34 to 3.36]. No difference was found regarding the odds of all-cause and cardiac death. The presence of ectasia was associated with higher odds of recurrent AMI, compared with controls [OR: 2.76, 95% CI:1.62 to 4.71]. The groups were comparable regarding the need for repeat revascularization, while the reports on stroke and heart failure were scarce. Conclusions: The results highlight the compounding effect of CAE on future MACE events in patients with AMI. Patients with AMI and CAE have higher odds of repeat AMI compared to patients without CAE, while mortality and repeat revascularization rates are similar. This might indicate the need for more aggressive treatment strategies in these patients.
