Abstract

Aims: The outcomes of patients presenting with acute myocarditis and life‐threatening ventricular arrhythmias (LT‐VA) are unclear. The aim of this study was to assess the incidence and predictors of recurrent major arrhythmic events (MAEs) after hospital discharge in this patient population. Methods and results: We retrospectively analysed 156 patients (median age 44 years; 77% male) discharged with a diagnosis of acute myocarditis and LT‐VA from 16 hospitals worldwide. Diagnosis of myocarditis was based on histology or the combination of increased markers of cardiac injury and cardiac magnetic resonance (CMR) Lake Louise criteria. MAEs were defined as the relapse, after discharge, of sudden cardiac death or successfully defibrillated ventricular fibrillation, or sustained ventricular tachycardia (sVT) requiring implantable cardioverter‐defibrillator therapy or synchronized external cardioversion. Median follow‐up was 23 months [first to third quartile (Q1–Q3) 7–60]. Fifty‐eight (37.2%) patients experienced MAEs after discharge, at a median of 8 months (Q1–Q3 2.5–24.0 months; 60.3% of MAEs within the first year). At multivariable Cox analysis, variables independently associated with MAEs were presentation with sVT [hazard ratio (HR) 2.90, 95% confidence interval (CI) 1.38–6.11]; late gadolinium enhancement involving ≥2 myocardial segments (HR 4.51, 95% CI 2.39–8.53), and absence of positive short‐tau inversion recovery (STIR) (HR 2.59, 95% CI 1.40–4.79) at first CMR. Conclusions: Among patients discharged with a diagnosis of myocarditis and LT‐VA, 37.2% had recurrences of MAEs during follow‐up. Initial CMR pattern and sVT at presentation stratify the risk of arrhythmia recurrence.

  • The incidence of sudden cardiac death from acute myocarditis in young adults is about 6% to 10%.

    “given an incidence of about 6% to 10% of sudden cardiac death from acute myocarditis in young adults.”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [256]

    The Introduction says sudden cardiac death is a possible outcome of acute myocarditis, but gives no incidence estimate. The Study population and Outcome sections concern patients who presented with life-threatening ventricular arrhythmias, not sudden-death incidence in young adults. Searches for the 6%–10% figure and for young adults found no passage supporting the claimed estimate. (LLM, conf=0.77)

  • In fulminant myocarditis, severe conduction abnormalities such as second- and third-degree atrioventricular blocks are common.

    “In fulminant myocarditis, severe conduction abnormalities such as second- and third-degree atrioventricular blocks are common”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [256]

    The Introduction describes fulminant myocarditis in terms of severe haemodynamic compromise, while the arrhythmic risk stratification section discusses life-threatening ventricular arrhythmias. Neither passage addresses how common second- or third-degree atrioventricular block is in fulminant myocarditis. Searches for those blocks and for conduction abnormalities found no relevant passage in our copy. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
