    Journal of Cardiovascular Translational Research https://doi.org/10.1007/s12265-020-09996-1 REVIEW ARTICLE Myocarditis in the Athlete: Arrhythmogenic Substrates, Clinical Manifestations, Management, and Eligibility Decisions Riccardo Vio1 & Alessandro Zorzi1 & Domenico Corrado1 Received: 3 October 2019 /Accepted: 24 March 2020 # Springer Science+Business Media, LLC, part of Springer Nature 2020 Abstract Myocarditis is as an important cause of sudden cardiac death (SCD) among athletes. The incidence of SCD ascribed to myocarditis did not change after the introduction of pre-participation screening in Italy, due to the transient nature of the disease and problems in the differential diagnosis with the athlete’s heart. The arrhythmic burden and the underlying mechanisms differ between the acute and chronic setting, depending on the relative impact of acute inflammation versus post-inflammatory myocardial fibrosis. In the acute phase, ventricular arrhythmias vary from isolated ventricular ectopic beats to complex tachy- cardias that can lead to SCD. Atrioventricular blocks are typical of specific forms of myocarditis, and supraventricular arrhyth- mias may be observed in case of atrial inflammation. Athletes with acute myocarditis should be temporarily restricted from physical exercise, until complete recovery. However, ventricular tachycardia may also occur in the chronic phase in the context of post-inflammatory myocardial scar. Keywords Myocarditis . Athletes . Sport .

The most common presentation was chest pain within 1–5 days after the second dose of mRNA COVID-19 vaccination. All patients had an elevated troponin. Cardiac magnetic resonance imaging revealed late gadolinium enhancement consistent with myocarditis in 69% of cases. All patients recovered clinically rapidly within 1–3 weeks. Most patients were treated with non-steroidal anti-inflammatory drugs for symptomatic relief, and 4 received intravenous immune globulin and corticosteroids. We speculate a possible causal relationship between vaccine administration and myocarditis. The data from our analysis confirms that all myocarditis and pericarditis cases are mild and resolve within a few days to few weeks.

This article is licensed under a Commons Attribution Non-Commercial 4.0 License ABSTRACT Acute non-rheumatic streptococcal myopericarditis (ANRSM) is a rare complication of an upper airway infection by streptococcus group A in developed countries. Cardiac involvement in bacterial infections must be adequately treated because it can lead to long-term complications. This case report describes recurrent ANRSM in an 18-year-old man, which illustrates how difficult and challenging the diagnosis of this disease can be. LEARNING POINTS • In developed countries, acute non-rheumatic streptococcal myopericarditis is a rare complication of an upper airway infection by streptococcus group A and can mimic acute myocardial infection with ST elevation. • The diagnosis is made on the basis of a recent upper airway infection by streptococcus group A in the absence of a rheumatic setting. • Cardiac imaging (mainly ultrasound and magnetic resonance) plays a major role in making the diagnosis.

Clinical manifestations can vary from life-threatening arrythmias to chronic conditions, such as heart failure or hypertension, which dramatically reduce quality of life of cancer survivors. Standard chemotherapy exerts its toxic effect mainly by inducing oxidative stress and genomic instability, while new targeted therapies work by interfering with signaling pathways important not only in cancer cells but also in myocytes. For example, Bruton’s tyrosine kinase (BTK) inhibitors interfere with class I phosphoinositide 3-kinase isoforms involved in cardiac hypertrophy, contractility, and regulation of various channel forming proteins; thus, off-target effects of BTK inhibitors are associated with increased frequency of arrhythmias, such as atrial fibrillation, compared to standard chemotherapy. In this review, we summarize current knowledge of cardiotoxic effects of targeted therapies used in hematology.

  • Myopericarditis Associated with Parainfluenza Virus Type I Infection
    Case Reports Acta Cardiol Sin 2006;22:163-9 Myopericarditis Associated with Parainfluenza Virus Type I Infection Jien-Jiun Chen,1 Ming-Tzer Lin,1 Lung-Chun Lin,1 Chuen-Den Tseng1 and Fu-Tien Chiang1,2 Myopericarditis is not uncommon, but often under-diagnosed. In fulminant cases, it may lead rapidly to circulatory failure or malignant arrhythmia, causing mortality. In this report, we describe a 41-year-old man who had episodes of convulsion one week after an upper respiratory tract infection. His electrocardiograms (ECGs) recorded during attack showed ventricular tachycardia. He had pulmonary edema and shock in the hospitalization course. The serial ECGs showed widespread PR depression, ST elevation and T-wave inversion afterwards, typical of myopericarditis change. The patient recovered finally. A paired serology test showed fourfold elevation of Parainfluenza virus type I antibody titer, suggesting that the parainfluenza virus might be the causative agent. This case illustrates that the parainfluenza virus might have a causative role in acute myopericarditis in which the clinical course is fulminant.

Remmelink, Department of Cardiology, Academic Medical Center, University of Amsterdam, Meibergdreef 9, 1105AZ Amsterdam, The Netherlands. Email: [email protected] Date accepted for publication 5 June 2012 Abstract We present a case of an uncommon viral myopericarditis in a 19-year-old man with chest pain. Electrocardiographic abnormalities and elevated cardiac enzymes were present. Myopericarditis of unknown origin was diagnosed following cardiac magnetic resonance imaging. During admission, the patient developed tonsillitis and serology tests confirmed an acute Epstein–Barr viral infection. Therefore, in acute myo(peri)carditis, we suggest early viral determination. Keywords Myopericarditis; Epstein-Barr virus; cardiac magnetic resonance imaging. Case report A 19-year-old man presented to the cardiac emergency room complaining of acute chest pain radiating to the left arm of 60 min duration, accompanied by dyspnea. The morning of presentation, he woke up at 05:00 h with a fever and sweating heavily. The day before he had muscle pains all over, and during a short period posture-dependent chest discomfort, especially when lying down. He had experienced some dyspnea, and a temperature rise to 398C. He had no medical history.

  • Myopericarditis Following Smallpox Vaccination Among Vaccinia-Naive US Military Personnel
    ORIGINAL CONTRIBUTION Myopericarditis Following Smallpox Vaccination Among Vaccinia-Naive US Military Personnel Jeffrey S. Halsell, DO Context In the United States, the annual incidence of myocarditis is estimated at 1 James R. Riddle, DVM, MPH to 10 per 100000 population. As many as 1% to 5% of patients with acute viral in- J. Edwin Atwood, MD fections involve the myocardium. Although many viruses have been reported to cause myopericarditis, it has been a rare or unrecognized event after vaccination with the Pierce Gardner, MD currently used strain of vaccinia virus (New York City Board of Health). Robert Shope, MD Objective To describe a series of probable cases of myopericarditis following small- Gregory A. Poland, MD pox vaccination among US military service members reported since the reintroduction of vaccinia vaccine. Gregory C. Gray, MD, MPH Design, Setting, Participants Surveillance case definitions are presented. The cases Stephen Ostroff, MD were identified either through sentinel reporting to US military headquarters surveillance Robert E. Eckart, DO using the Defense Medical Surveillance System or reports to the Vaccine Adverse Event Reporting System using International Classification of Diseases, Ninth Revision. The cases Duane R. Hospenthal, MD, PhD occurred among individuals vaccinated from mid-December 2002 to March 14, 2003. Roger L.
