Elevated high-sensitive cardiac troponin T in emergency department patients: insights from a retrospective descriptive cohort study.
Article in International journal of emergency medicine, 2024. 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
backgroundHigh-sensitive cardiac troponin T (hs-cTnT) assessments are routinely conducted in German emergency departments (EDs). However, data describing a large number of ED patients with pathological hs-cTnT levels and subsequent clinical outcomes are limited.
methodsThis retrospective descriptive analysis included 141.892 patients who presented to the interdisciplinary ED at Klinikum rechts der Isar in Munich, Germany, between January 2019 and December 2021. Patients with trauma diagnoses were excluded, focusing on those with elevated hs-cTnT levels. These patients were categorized into three groups based on the International Classification of Procedures in Medicine (ICPM): those with elevated hs-cTnT who received no coronary angiography (NCA), those who underwent diagnostic coronary angiography (DCA), and those who received percutaneous coronary intervention (PCI). The objective of this study was to characterize a large emergency department patient cohort and assess their subsequent clinical outcomes.
resultsAfter initial Manchester Triage Sytem (MTS) categorization, 32.6% (46.307/141.892) of patients were identified as non-trauma cases. Of these, 9.9% (4.587/46.307) had hs-cTnT levels exceeding 14 ng/L. Within this subset, 70.4% (3.230/4.587) did not undergo coronary angiography, 15.4% (705/4.587) underwent DCA and 14.2% (652/4.587) received PCI. Chest pain occurred more frequently in the PCI group (28.0%, 160/652) compared to the DCA group (18.3%, 113/705) or NCA group (5.7%, 159/3230), p < 0.001. However, breathing problems occurred more frequently in the NCA group (23.2%, 647/3230) compared to the PCI group (17.7%, 101/652) or DCA group (21.8%, 135/705), p < 0.001. Also, collapse was more frequent in patients in the NCA group (4.0%, 112/3230) compared to the DCA group (3.4%, 21/705) or PCI group (3.5%, 20/652), p < 0.001. Overall, in-hospital mortality was significantly higher in the NCA group (7.9%, 256/3230) compared to the DCA group (2.3%, 16/705) or PCI group (4.1%, 27/652), p < 0.001.
conclusionEmergency patients with elevated hs-cTnT who did not undergo coronary angiography faced a higher risk of in-hospital mortality in our retrospective descriptive study. Given the heterogeneous nature of presenting complaints in emergency departments, identifying at-risk patients can pose challenges for treating physicians.
