Cardio-hepatic injury phenotypes and short-term outcomes in acute decompensated heart failure.

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
backgroundAbnormal liver biochemistry is common in acute decompensated heart failure (ADHF), yet most studies evaluate individual markers rather than clinically meaningful patterns of hepatic involvement. We examined whether cardiohepatic injury phenotypes derived from routine liver tests identify distinct short-term prognostic profiles in patients hospitalized with ADHF.
methodsIn this retrospective cohort study, we included consecutive adults hospitalized with ADHF between December 2006 and 2017. Using peak in-hospital values of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and total bilirubin, patients were classified into four phenotypes: no hepatic injury, hepatocellular injury, cholestatic injury, or combined injury. Associations with in-hospital mortality were evaluated using multivariable logistic regression. Post-discharge outcomes (30-day mortality, readmission, and their composite) were analyzed using Cox and Fine-Gray models.
resultsAmong 8332 ADHF admissions, 6792 (81.5%) had sufficient data for phenotype classification: 58.1% had no hepatic injury, 22.1% hepatocellular injury, 13.1% cholestatic injury, and 6.7% combined injury. In-hospital mortality differed markedly across phenotypes (3.5%, 16.3%, 9.0%, and 24.3%, respectively; p < 0.001). After adjustment, all injury phenotypes independently predicted in-hospital death compared with no injury. Among 6128 patients included in adjusted post-discharge analyses, hepatocellular and combined injury were independently associated with higher 30-day mortality and the composite outcome, whereas isolated cholestatic injury was not. Hepatocellular and combined injury independently predicted 30-day readmission.
conclusionsRoutine liver test patterns identify clinically meaningful cardiohepatic phenotypes in ADHF. While all hepatic injury phenotypes are associated with increased in-hospital mortality, only phenotypes with hepatocellular involvement predict adverse early post-discharge outcomes. Pattern-based interpretation of liver tests may improve early risk stratification in patients hospitalized with ADHF.
