The predictive value of NT-proBNP/ALB ratio for in-hospital pericardial effusion in young acute myocardial infarction patients.

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: The incidence of acute myocardial infarction (AMI) in young adults (<45 years) is increasing. Pericardial effusion (PE) is a notable complication reflecting hemodynamic instability and severe inflammation; however, sensitive biomarkers for early risk stratification in this specific demographic remain under-investigated. The N-terminal pro-B-type natriuretic peptide to albumin ratio (NT-proBNP/ALB) integrates hemodynamic load with inflammatory-nutritional status, yet its prognostic utility for PE in young AMI patients is unexplored. Methods: This retrospective observational study enrolled 1,974 young AMI patients admitted to the First Affiliated Hospital of Xi'an Jiaotong University between January 2018 and October 2025. Patients were categorized into PE and non-PE groups based on echocardiographic findings. Multivariate logistic regression was utilized to identify independent predictors. The incremental predictive value of the log-transformed NT-proBNP/ALB ratio (lg BNP/ALB) and Plateletcrit (PCT, a platelet mass marker) was evaluated using Receiver Operating Characteristic (ROC) curves, Net Reclassification Improvement (NRI), and Integrated Discrimination Improvement (IDI). Results: In-hospital PE occurred in 7.1% (141/1,974) of the cohort. Multivariate analysis identified lg (NT-proBNP/ALB) (adjusted OR: 3.23, 95% CI: 1.30-5.78, Conclusion: The admission NT-proBNP/ALB ratio and PCT were independently associated with in-hospital pericardial effusion in young AMI patients and provided incremental value for early risk stratification beyond conventional clinical indicators.
