Review
Cardiovascular involvement is an uncommon but severe complication of Epstein-Barr virus (EBV) infection caused by direct damage and immune injury. Recently, it has drawn increasing attention due to its dismal prognosis. It can manifest in various ways, including coronary artery dilation (CAD), coronary artery aneurysm (CAA), myocarditis, arrhythmias, and heart failure, among others. If not treated promptly, cardiovascular damage can progress over time and even lead to death, which poses a challenge to clinicians. Early diagnosis and treatment can improve the prognosis and reduce mortality. However, there is a lack of reliable large-scale data and evidence-based guidance for the management of cardiovascular damage. Consequently, in this review, we attempt to synthesize the present knowledge of cardiovascular damage associated with EBV and to provide an overview of the pathogenesis, classification, treatment, and prognosis, which may enhance the recognition of cardiovascular complications related to EBV and may be valuable to their clinical management.

Review
Monkeypox virus has emerged in different parts of the world with varying clinical symptoms and outcomes. To date, only a few studies have reported cardiac manifestations among monkeypox-infected patients. We aim to systematically evaluate the symptoms, imaging findings, management, and outcomes among monkeypox-induced myocarditis patients. We conducted a systematic literature search in PubMed, Embase, and Scopus from inception till 5th January 2023 by using predefined MESH terms and "AND" and "OR." The following search terms were used: "monkeypox virus" AND "myocarditis." A total of 6 studies with 9 monkeypox-induced myocarditis patients were included in this analysis. The mean age of patients was 33.6 years, with all being male patients. The most common symptoms were fever (89%) and chest pain (100%). Electrocardiogram findings showed 44% of patients had ST-elevation, and 22% had sinus tachycardia. The echocardiographic findings show a mean ejection fraction of 52.14%, while 57% of patients had preserved ejection fraction, and 67% had normal wall motion. Cardiac magnetic resonance findings show 40% of patients had late gadolinium enhancement, and 40% had edema. Management of patients was primarily supportive (33%), and 33% of patients were administered Beta blockers and ACE inhibitors. Overall all patients survived with a good prognosis. Our study's findings show that all cases were reported among male patients with the most common symptoms of chest pain. The overall prognosis was good, with no mortality reported. Infected patients complaining of chest pain should not be ignored, and proper investigation of myocarditis must be considered.

PURPOSE OF REVIEW
Myocarditis is a disease caused by inflammation of the heart that can progress to dilated cardiomyopathy, heart failure, and eventually death in many patients. Several etiologies are implicated in the development of myocarditis including autoimmune, drug-induced, infectious, and others. All causes lead to inflammation which causes damage to the myocardium followed by remodeling and fibrosis. This review aims to summarize recent findings in biomarkers for myocarditis and highlight the most promising candidates.
RECENT FINDINGS
Current methods of diagnosing myocarditis, including imaging and endomyocardial biopsy, are invasive, expensive, and often not done early enough to affect progression. Research is being done to find biomarkers of myocarditis that are cost-effective, accurate, and prognostically informative. These biomarkers would allow for earlier screening for myocarditis, as well as earlier treatment, and a better understanding of the disease course for specific patients. Early diagnosis of myocarditis with biomarkers may allow for prompt treatment to improve outcomes in patients.

Review
Myocarditis is an illness characterized by myocardial infiltration with inflammatory cells and non-ischemic myocytic necrosis. The clinical presentation of myocarditis varies widely and diagnosis is sometimes difficult to establish. The current incidence of myocarditis is also difficult to determine as endomyocardial biopsy, the diagnostic gold standard, is unfrequently used, or even not justified. The leading causes are infections, immune-mediated injury and toxins. Prognosis is most often good but, in some patients, the disease can be fulminant with progression to cardiogenic shock, or occurrence of sudden cardiac death. Prognosis in myocarditis patients varies according to the underlying aetiology. Treatment is generally symptomatic, but in some cases, a specific therapy is appropriated as a function of the corresponding aetiology. This paper aims to review current knowledge concerning myocarditis, with particular emphasis on «urgent» situations.

PURPOSE OF REVIEW
The present review discusses the neurological complications associated with myocarditis of different etiologies.
RECENT FINDINGS
Myocarditis can be idiopathic or caused by different conditions, including toxins, infections, or inflammatory diseases. Clinical findings are variable and range from mild self-limited shortness of breath or chest pain to hemodynamic instability which may result in cardiogenic shock and death. Several neurologic manifestations can be seen in association with myocarditis. Tissue remodeling, fibrosis, and myocyte dysfunction can result in heart failure and arrhythmias leading to intracardiac thrombus formation and cardioembolism. In addition, peripheral neuropathies, status epilepticus, or myasthenia gravis have been reported in association with specific types of myocarditis. Multiple studies suggest the increasing risk of neurologic complications in patients with myocarditis. Neurologists should maintain a high suspicion of myocarditis in cases presenting with both cardiovascular and neurological dysfunction without a clear etiology.

Review
Cardiovascular complications (especially myocarditis) related to COVID-19 viral infection are not well understood, nor do they possess a well recognized diagnostic protocol as most of our information regarding this issue was derived from case reports. In this article we extract data from all published case reports in the second half of 2020 to summarize the theories of pathogenesis and explore the value of each diagnostic test including clinical, lab, ECG, ECHO, cardiac MRI and endomyocardial biopsy. These tests provide information that explain the mechanism of development of myocarditis that further paves the way for better management.

Review
"Since the pathological conditions take place at the cellular level, viral myocarditis and postinfectious autoimmunity can be suggested but not diagnosed clinically. All clinical methods including imaging techniques are misleading if infectious agents are involved. Accurate diagnosis demands simultaneous histologic, immunohistochemical, and molecular biological workup of the tissue. If the primary infectious or immune-mediated causes of the disease are carefully defined by clinical and biopsy-based tools, specific antiviral treatment options in addition to basic symptomatic therapy are available under certain conditions. These may allow a tailored cause-specific treatment that improves symptoms and prognosis of patients with acute and chronic disease."

Review
Coronavirus disease-2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2, is currently in a pandemic outbreak and has become a global health issue. In addition to the primarily involvement of the respiratory system, myocarditis is considered an important and fatal lesion in patients with COVID-19. However, effective therapeutic methods are currently lacking. The cholinergic anti-inflammatory pathway (CAP) has been demonstrated to suppress pro-inflammatory cytokine production and control inflammation in sepsis and other medical conditions. Therefore, the CAP may be a potential and effective therapeutic method for COVID-19-related myocarditis. This article reviews the relationship between COVID-19-related myocarditis and the CAP and discusses the CAP as a potential therapeutic modality in the treatment of COVID-19-related myocarditis.

The term myocarditis describes inflammatory disorders of the heart muscle of varied infectious and non-infectious origins. It can be caused by any kind of infection, drugs, toxic substances, or be associated with autoimmune conditions. Viruses are the main causes at least in developed countries. Acute myocarditis most commonly results from an external inflammatory trigger inducing the host immune response, which may range from minimally transient response to fulminant overwhelming cellular infiltration. If the immune system does not eliminate the infectious pathogen early on, chronic infection develops with or without accompanying inflammation. Post-infectious autoimmunity may persist despite effective virus clearance. Since the pathological conditions take place at the cellular level, viral myocarditis and postinfectious autoimmunity can be suggested but not diagnosed clinically. All clinical methods including imaging techniques are misleading if infectious agents are involved. Accurate diagnosis demands simultaneous histologic, immunohistochemical and molecular biological workup of the tissue. If the primary infectious or immune-mediated causes of the disease are carefully defined by clinical and biopsy based tools, specific antiviral treatment options in addition to basic symptomatic therapy are available under certain conditions. These may allow a tailored cause-specific treatment that improves symptoms and prognosis of patients with acute and chronic disease.
