IVUS derived plaque characteristics and outcomes in patients with acute coronary syndrome undergoing percutaneous intervention.

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
backgroundNo/slow flow after percutaneous intervention(PCI) for acute coronary syndromes (ACS) is common. Whether a comprehensive intravascular ultrasound (IVUS) analysis of atherosclerotic plaque can define characteristics which predict suboptimal flow following PCI is largely unknown.
objectivesTo identify IVUS correlates of suboptimal flow in patients with ACS undergoing PCI. MATERIALS &
methodsWe performed a prospective multicentre, investigator initiated study. Patients with ACS, who underwent IVUS guided PCI were enrolled. Clinical, angiographic and imaging characteristics of patients who developed suboptimal flow after PCI were analysed and compared with patients with normal flow.
resultsBetween October 2021 and August 2022, we enrolled 187 patients (195 lesions) with ACS who underwent IVUS guided PCI. Mean age of patients was 58 ± 10.4 years; Incidence of slow/no reflow in our study was 14/195 (7.2 %). Presentation as ST elevation myocardial infarction, presence of angiographically complex lesion type (type B2/C) and pre procedural TIMI flow 0 were significantly more in patients who developed suboptimal flow after PCI. Pre PCI plaque attenuation length (9.51 mm Vs 4.35 mm p = 0.037), lesion site positive remodelling (Odds ratio 6.4 : 95 % CI; 1.1-38.4 p = 0.042) were predictors of slow flow.Post PCI length of plaque prolapse (9.73 mm Vs 6.58 mm p = 0.029) correlated with slow flow.
conclusionsPlaque characteristics on IVUS in patients with ACS helps to identify patients who may develop suboptimal flow following PCI.
