Diagnostic trends in patients hospitalized with suspected myocarditis: 10-year data from the nationwide MYO-PL database.
Article in Cardiology journal, 2026. 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
backgroundMyocarditis poses a great diagnostic challenge to clinicians, as the most sensitive diagnostic tools are not easily accessible in many hospitals. Clinical suspicion of myocarditis is based on clinical symptoms and additional tests' abnormalities. The diagnosis should be confirmed by endomyocardial biopsy (EMB) - the gold standard for the diagnosis of myocarditis. The study aimed to assess trends in the use of diagnostic procedures performed in all patients hospitalized with suspected myocarditis in Poland between 2011-2019.
methodsThe nationwide MYO-PL database was derived from the database of the national healthcare insurer and created to identify hospitalization records with a primary diagnosis of myocarditis. We evaluated the use of recommended diagnostic procedures in this group of 19 978 patients within 6 months of the diagnosis of myocarditis.
resultsEchocardiography was the most frequently used imaging technique among patients, and the number of patients who underwent this procedure between 2011-2019 rose every year (71.3-86.1%). Use of nuclear medicine procedures remained < 1% regardless of the year. Biomarkers measurements during primary hospitalization were performed in 13.8% (brain natriuretic peptides) and 41.3% (troponins) of patients. Interestingly, EMB was performed in less than 1% of patients. The most sensitive noninvasive test (cardiac magnetic resonance) was performed in 16.4% of patients (7.2-29.2% within 10 years). Most diagnostic tests were less frequently performed in females.
conclusionsThe results highlight that the management of patients with myocarditis could be significantly improved if state-of-the-art diagnostic methods were followed according to guidelines.
