Intravascular ULTRA sound-guided percutaneous coronary intervention in patients with STEMI: Rationale and design of the ULTRA-STEMI trial.
Article in World journal of cardiology, 2025. 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
backgroundSafety and efficacy of intravascular ultrasound (IVUS) guidance in percutaneous coronary intervention (PCI) has been consistently shown in recent trials. However, prospective data on the clinical effects of IVUS usage in primary PCI are still warranted. The ULTRA-STEMI trial is a prospective investigator-initiated observational single-center cohort trial aiming to enroll 80 patients with STEMI.
aimTo investigate the outcomes of patients with STEMI undergoing IVUS-guided PCI and correlate derived IVUS measurements with clinical, procedural, imaging and follow-up outcomes of interest.
methodsStudy participants will undergo primary PCI as per standardized procedures. IVUS pullbacks will be performed pre-intervention, post-lesion preparation, post-intervention and post-optimization using a 20 MHz digital IVUS (Eagle Eye Platinum, Philips). Manual thrombus aspiration will be performed in cases of high thrombus burden. The aspirated thrombi will be scanned with micro-computed tomography to extract volumetric measurements of the aspirated thrombotic burden. Moreover, angiographic, peri-procedural and 3-year follow-up data will be gathered. Co-primary endpoints will be cardiovascular mortality and target vessel failure, defined as the composite of: Cardiovascular mortality, target vessel myocardial infarction and/or clinically driven target vessel revascularization.
resultsThe results of the study are expected by the third quarter of 2029.
conclusionThe ULTRA-STEMI trial will add to the existing literature the clinical, angiographic, micro-computed tomography and follow-up outcomes of IVUS-guided PCI in 80 patients presenting with STEMI.
