Myocarditis is an established but rare adverse event following administration of messenger RNA-based coronavirus disease 2019 (COVID-19) vaccines and is most common in male adolescents and young adults. Symptoms typically develop within a few days of vaccine administration. Most patients have mild abnormalities on cardiac imaging with rapid clinical improvement with standard treatment. However, longer term follow-up is needed to determine whether imaging abnormalities persist, to evaluate for adverse outcomes, and to understand the risk associated with subsequent vaccination. The purpose of the review is to evaluate the current literature related to myocarditis following COVID-19 vaccination, including the incidence, risk factors, clinical course, imaging findings, and proposed pathophysiologic mechanisms.

Risk impact of SARS-CoV-2 coronavirus and spike protein on cardiac tissue: a comprehensive review.

The global COVID-19 pandemic, caused by SARS-CoV-2, has led to significant morbidity and mortality, with a profound impact on cardiovascular health. This review investigates the mechanisms of SARS-CoV-2's interaction with cardiac tissue, particularly emphasizing the role of the Spike protein and ACE2 receptor in facilitating viral entry and subsequent cardiac complications. We dissect the structural features of the virus, its interactions with host cell receptors, and the resulting pathophysiological changes in the heart.

Background: Polyarteritis nodosa (PAN) is a rare and serious form of systemic necrotizing vasculitis that predominantly affects medium and small-sized arteries, with central nervous system involvement being particularly uncommon. Treatment strategies are tailored according to the extent and severity of the disease. While conventional therapy includes glucocorticoids and conventional disease-modifying-rheumatic drugs (cDMARDs), biologic agents may be critical for severe and refractory cases.

Objective: The purpose of this systematic review is to evaluate the original peer-reviewed studies on athletes who developed myocarditis after coronavirus disease (COVID-19) infection or after COVID-19 mRNA vaccination. Both entities likely have an immunologic component. We discuss elite, professional, college, and adolescent athletes.

Purpose Of Review: This review aims to assess the current landscape of animal models used in myocarditis research, with a focus on understanding their utility in uncovering the pathophysiology of the disease. The goal is to evaluate these models' strengths and weaknesses and propose optimizations to make them more relevant and reliable for both mechanistic studies and therapeutic interventions in myocarditis.

Recent Findings: Recent studies have primarily utilized animal models, particularly viral and autoimmune myocarditis models, to study disease mechanisms.
