From 2 randomized trials, we identified 471 patients (138 patients with acute myocardial infarction [AMI] vs 333 patients with stable angina or unstable angina [SA\/UA]) treated by DESs who underwent serial optical coherence tomography (OCT) from postprocedure to 3 months. At 3-month follow-up OCT, malapposed strut percentage was higher in AMI than in SA\/UA (5.3% vs 0.7%, P &lt; .001); it was markedly increased from postprocedure in AMI (2.0%-5.3%, P &lt; .001), whereas it decreased in SA\/UA (1.7%-0.7%, P &lt; .001). Patients with AMI showed a higher risk of persistent (59% vs 37%; P &lt; .001) or late-acquired malapposition (15% vs 8%; P = .04). Uncovered strut percentage at 3 months was also higher in AMI than in SA\/UA (13.1% vs 6.7%, P &lt; .001). The AMI presentation was the significant risk factor for both significant stent malapposition (SM, \u2265200 \u03bcm; odds ratio [OR] = 3.45, CI = 1.85-7.14, P &lt; .001) and uncovered stent (% uncovered struts &gt;6.0%; OR = 2.44, CI = 1.35-4.76, P = .004), together with malapposed distance and postprocedural thrombi. Further, AMI presentation was the predictor for the occurrence of early period late-acquired and persistent malapposition. Serial OCT comparison analyses showed that patients with AMI compared with patients with SA\/UA showed more delayed strut coverage, more severe degree SM or uncovered stents, and higher incidences of early period persistent or late-acquired SM.<\/jats:p>","DOI":"10.1177\/0003319720980607","type":"journal-article","created":{"date-parts":[[2020,12,21]],"date-time":"2020-12-21T03:02:04Z","timestamp":1608519724000},"page":"381-391","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Differential
