Identification of completed coronary stent healing by optical coherence tomography - validation study with histopathology in porcine model of coronary restenosis.
Article in Cardiology journal, 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
backgroundThe potential of optical coherence tomography (OCT) is limited by incomplete validation with histopathology. The study aimed to assess whether OCT can identify a completely healed coronary stent. MATERIAL AND
methodsThe study included 40 swine and total of 106 stents (82 DES, 24 BMS). Follow-up OCT and histopathology examination was done after 28 days (n = 53) and 90-days (n = 53). 273 frames were matched between histopathology and OCT. Histopathologic criteria for completed healing: high endothelialization score (2-3), low inflammation score (0-1), low fibrin score (0-1), high neointimal smooth muscle score (2-3) and lack of binary restenosis.
resultsPredictors of a well healed stent were presence of homogenous neointima (OR: 2.53) and the total number of struts per section (OR: 1.11). The presence of microvessels (OR: 0.28) and increasing neointimal area (OR: 0.65) predicted incomplete healing. Cutoff values were identified: inflammation score was the highest in segments with neointima thickness over 0.35 mm. Persistent fibrin deposits were found at 28-day follow-up in DES with less than 13 embedded struts per section and neointima area less than 2.234 mm². The number of embedded struts per section showed a positive correlation with the healing score, while both protruding covered and protruding uncovered struts showed a negative correlation.
conclusionsOCT demonstrated moderate ability to predict completed stent healing.
