Percutaneous Coronary Intervention in Patients with Coronary Artery Ectasia: A Retrospective Single-center Study.

Objective: This retrospective single-center study aimed to compare the outcomes of ad-hoc versus planned percutaneous coronary intervention (PCI) in patients with coronary ectasia. We investigated baseline characteristics, primary and secondary outcomes, and predictors of mortality in a cohort of patients who underwent PCI procedures.

Methods: Data from 3,179 patients (ad-hoc PCI, n = 1,286; planned PCI, n = 1,893) with coronary ectasia were analyzed. Baseline characteristics, including age, gender, comorbidities, and lesion characteristics, were compared between the two groups. Primary outcomes included technical success and stent deployment success, while secondary outcomes encompassed major adverse cardiovascular events (MACE), all-cause mortality, recurrent angina, and target lesion revascularization. Logistic regression was utilized to identify predictors of mortality.

Results: The ad-hoc PCI group exhibited a higher prevalence of comorbidities, including hypertension, diabetes mellitus, smoking history, and multi-vessel disease (all p < 0.05). While technical success and stent deployment success rates were lower in the ad-hoc PCI group (p < 0.05), patients undergoing planned PCI demonstrated significantly lower rates of MACE, all-cause mortality, recurrent angina, and target lesion revascularization (all p < 0.05). Logistic regression analysis identified older age, male gender, hypertension, diabetes mellitus, smoking history, and multi-vessel disease as independent predictors of mortality (all p < 0.05). Importantly, coronary ectasia emerged as an additional predictor of mortality (p = 0.002).

Conclusion: Our study indicates that planned PCI is associated with improved procedural outcomes and lower rates of mortality and adverse events compared to ad-hoc PCI in patients with coronary ectasia.
