ABSTRACT
BACKGROUND:
The clinical significance of coronary artery ectasia (CAE) is not yet fully understood. We aimed to examine differences in clinical and procedural characteristics, clinical management, and outcomes in patients with CAE undergoing primary percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction (STEMI).METHODS:
This was a retrospective analysis of consecutive patients presenting with STEMI with a culprit native coronary artery from July 2015 to June 2019. Patients were divided into CAE and Non-CAE groups as detected on coronary angiography during PPCI. Comparison between groups was made for baseline clinical and procedural characteristics, as well as complications, pharmacological treatment, and follow-up outcomes.RESULTS:
36/1780 (2.0%) patients were found to have CAE. Patients with CAE had a median age of 57.1 ± 11.7 years and were more likely to be male 33/36 (91.7%). Diabetes was less commonly seen in the CAE group (11.1% vs 31.4%, p = 0.010), and there were no differences in the proportion of patients with hypertension and hyperlipidemia. Patients with CAE had more involvement of right coronary artery (RCA) culprit vessel (63.9% vs. 38.4%, p = 0.026), less coronary stenting (25.0% vs 87.2%, p < 0.001) and post-PPCI TIMI 3 flow (69.4% vs 95.5%, P < 0.001), and were more likely to be discharged with oral anticoagulants (36.1% vs 7.6%, p < 0.001). At 3-year follow-up, all-cause mortality rates were higher in the non-CAE group (0.0% vs 11.5%, p < 0.028), suggesting that CAE was not associated with unfavorable long-term outcome. On multivariate analysis, CAE was not an independent predictor of MACE.CONCLUSION:
Despite lower rates of post-PPCI TIMI 3 flow, CAE was not associated with unfavorable long-term outcome.Palavras-chave
