Incidence of Adverse Cardiac Events After Liver Transplantation in Patients With Different Hemodynamic Classifications of Pulmonary Hypertension.

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
Introduction: Pulmonary hypertension (PH) in liver transplantation candidates is associated with elevated morbidity and mortality. Few studies have investigated whether different categories of PH based off hemodynamic characteristics portend worse outcomes. Furthermore, there have been newly defined parameters for PH classifications. Therefore, we aimed to compare postoperative outcomes after liver transplantation in patients within different newly established hemodynamic categories of PH. Methods: This was a 20-year single-center retrospective observational study of adult patients undergoing liver transplantation. Patients with a diagnosis of PH and confirmatory right heart catheterization (RHC) were included in the study. Based off pulmonary artery wedge pressure (PAWP) and Wood units (WU), patients were categorized into four groups: precapillary (PrePH), isolated postcapillary (IpcPH), combined postcapillary (CpcPH), unclassified (UncPH). Our primary outcome was a composite of adverse cardiac events within 30 days postoperatively. Secondary outcomes included prolonged ventilation, acute kidney injury, and mortality at 30 days, 6 months, and 1 year. Results: Of the 2409 patients who underwent liver transplantation in the study period, 80 patients met criteria for inclusion. The incidences of ACEs were 0% in PrePH, 31.4% in IpcPH, 25.0% in CpcPH, and 10.3% in UncPH ( Conclusion: In this single-center study, we observed that patients with isolated precapillary PH did not have adverse cardiac events. Instead, patients with elevated PAWP, indicating postcapillary PH, were more likely associated with adverse cardiac events. This observation is seen despite milder pulmonary disease, as intended by newly established definitions for PH. Further investigation is warranted, as there may be prognostic implications that can drive future guidelines for liver transplantation in patients with PH.
