One-Year Clinical Outcomes in Acute ST-Segment Elevation Myocardial Infarction Patients Undergoing Optical Coherence Tomography-Guided Primary Percutaneous Coronary Intervention: A Comparative Study.
Article in Medical science monitor : international medical journal of experimental and clinical research, 2024. 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
BACKGROUND Percutaneous coronary intervention (PCI) with angiography guidance is a common procedure. Optical coherence tomography (OCT) is a non-invasive imaging method that uses light waves. This study from a single center aimed to compare 1-year outcomes in 75 patients with acute ST-segment elevation myocardial infarction (STEMI) who underwent OCT-guided primary PCI, with 163 patients with acute STEMI who underwent PCI without OCT guidance from February 2019 to July 2021. MATERIAL AND METHODS Patients with acute STEMI were enrolled from February 2019 to July 2021. Seventy-five patients underwent OCT-guided PCI (OCT group), while 163 underwent PCI without OCT (control group). Baseline characteristics, in-hospital mortality, target lesion revascularization, post-MI heart failure, and 1-year all-cause mortality were compared between groups. RESULTS The OCT group had lower diabetes mellitus and hyperlipidemia prevalence. Additionally, they experienced longer procedures (OCT: 50.45±21.75 min; control: 33.80±14.44 min; P<0.001). After PCI, the control group had lower left ventricular ejection fractions (OCT: 53.4%±10.5%; control: 47.8%±12.4%; P<0.001) and higher post-MI heart failure rates (OCT: 2.7%; control: 11.0%; P=0.030). Notably, the 1-year all-cause mortality rate was significantly lower in the OCT group (OCT: 1.3%; control: 8.0%; P=0.043). CONCLUSIONS During the 1-year follow-up, patients who received OCT-guided primary PCI experienced a notably lower rate of post-MI heart failure than did those who underwent primary PCI without OCT guidance. Importantly, the application of OCT in primary PCI procedures did not result in a higher incidence of distal embolism, even in cases with a significant thrombus burden.
