Clinical Impact and Lesion Characteristics of Suboptimal Optical Coherence Tomography Stent Deployment in Patients With Acute Myocardial Infarction.
Article in Journal of the American Heart Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSuboptimal stent deployment detected by optical coherence tomography (OCT) correlates with adverse outcomes, yet its long-term prognosis and associations with lesion characteristics in patients with acute myocardial infarction (MI) receiving drug-eluting stents remain unclear. This study aimed to investigate the impact of OCT-defined stent parameters on long-term outcomes and identify lesion features predictive of suboptimal stent deployment in patients with acute MI.
methodsBetween January 2018 and December 2020, patients with acute MI undergoing successful intervention with drug-eluting stents and postprocedural OCT imaging at the target lesions were included. The end point was device-oriented cardiovascular events, a composite of cardiac death, target-vessel related MI, and target-lesion revascularization. Suboptimal OCT stent deployment was defined as the presence of ≥1 OCT findings significantly associated with device-oriented cardiovascular events. In a subgroup with preprocedural OCT imaging for target lesions, lesion morphology was assessed.
resultsAmong 881 patients (906 lesions with final OCT imaging), minimum stent area<4.5 mm
conclusionsSuboptimal stent deployment, defined by specific quantitative OCT criteria, was associated with device failure at long-term follow-up in patients with acute MI successfully treated with drug-eluting stents. Specific OCT-identified lesion characteristics were associated with suboptimal OCT stent deployment.
