Quantitative myocardial blush score (QuBE) allows the prediction of heart failure development in long-term follow-up in patients with ST-segment elevation myocardial infarction: Proof of concept study.

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
backgroundAcute myocardial infarction (AMI) might lead to left ventricular remodeling. Adequate myocardial perfusion is critical to prevent this adverse remodeling. Quantitative myocardial blush evaluator (QuBE) software, available on-line, is a simple analysis tool which enables the precise quan-tification of myocardial perfusion in the infarct area immediately after interventional treatment. The aim of this study was to assess whether the results of QuBE analysis might predict the development of heart failure (HF) in AMI patients in 3 year-long follow-up.
methodsNinety five patients with first AMI, single vessel coronary artery disease, Killip class I at presentation were enrolled in the study. Angiograms were reanalyzed using the on-line QuBE software. Data on heart failure development (ICD 10 codes I50) provided by the National Health Fund were considered as primary outcome.
resultsQuBE values ranged from 0.0 to 25.3 arbitrary units, mean value was 9.9 ± 5.2 arbitrary units. QuBE correlated positively with myocardial blush grade (MBG; Spearman R = 0.342 at p < 0.05). Multivariate Cox proportional hazard modeling, adjusted for initial Thrombolysis in Myocardial In-farction (TIMI flow, and TIMI thrombus grade indicated QuBE score (1 unit increase - HR 0.919, 95% CI 0.846-0.999, p = 0.049) and left ventricular ejection fraction at discharge (1% increase - HR 0.936, 95% CI 0.902-0.971, p = 0.000) as independent predictors of HF development.
conclusionsThe QuBE assessment of myocardial perfusion allows the prediction of HF development in the post-infarction period in this highly selective group of patients.
