Overview
Historical Perspective
- [Disease name] was first discovered by [scientist name], a [nationality + occupation], in [year] during/following [event].
- In [year], [gene] mutations were first identified in the pathogenesis of [disease name].
- In [year], the first [discovery] was developed by [scientist] to treat/diagnose [disease name].
Classification
- [Disease name] may be classified according to [classification method] into [number] subtypes/groups:
- [group1]
- [group2]
- [group3]
- Other variants of [disease name] include [disease subtype 1], [disease subtype 2], and [disease subtype 3].
Pathophysiology
- Studies have demonstrated that COVID-19 interacts with the cardiovascular system, thereby causing myocardial injury and dysfunction as well as increasing morbidity among patients with underlying cardiovascular conditions.
- Among patients with COVID-19, there is a high prevalence of cardiovascular disease, and >7% of patients experience myocardial injury from the infection.[1]
- Myocarditis is an inflammatory disease of the heart characterized by inflammatory infiltrates and myocardial injury without an ischemic cause.[2]
- The major cause of myocarditis in the United States and other developed countries is viral.[3] [4]
- A number of cases of myocarditis have been reported in COVID-19 patients.[5][6][7][8]
- Myocarditis has also been reported as the cause of death in some COVID-19 patients.[9]
- The mechanism is unknown, though several have been proposed based on the limited data outside of case reports.
- Proposed pathophysiology of SARS-CoV-2 myocarditis
- SARS-CoV-2 infection is caused by binding of the viral surface spike protein (primed by TMPRSS2 - Transmembrane Protease Serine 2) to the human angiotensin-converting enzyme 2 (ACE2) receptor.[10]
- ACE2 is expressed in the lung, principally type II alveolar cells which appears to be the principal portal of entry.[11]
- ACE2 is highly expressed in the heart as well.[12]
- Naive T lymphocytes can be primed for viral antigens via antigen-presenting cells and cardio-tropism by the heart-produced hepatocyte growth factor (HGF) which binds c-Met, an HGF receptor on T lymphocytes.[13]
- The primed CD8+ T lymphocytes migrate to the cardiomyocytes and through cell-mediated cytotoxicity, cause myocardial inflammation.
- In the cytokine storm syndrome, proinflammatory cytokines such as Interleukin-6 (IL-6) are released into the circulation, which further augments T-lymphocyte activation and causes the release of more cytokines.[14]
- Cytokine storms result in increased vascular wall permeability and myocardial edema.[7][5]
- Thus a positive feedback loop of immune activation and myocardial damage is established.[15][2]
- Other proposed mechanism includes damage to myocardial cells resulting from respiratory dysfunction and hypoxemia due to COVID-19.
- Pathological changes in the myocardium
- They could be due to viral replication in the myocardium or immune responses caused by the infection or due to systemic responses to respiratory failure.
- Mononuclear inflammatory infiltration has been observed in the heart tissue in COVID-19 autopsy studies.[16]

Signs and Symptoms
Clinical presentation of SARS-CoV-2 myocarditis varies among cases from mild to severe to fulminant.
- Mild - fatigue and dyspnea,[6][7], chest pain or chest tightness on exertion.[5][8]
- Severe - Many patients deteriorate and show symptoms of tachycardia and acute-onset heart failure with cardiogenic shock.[5][6][7] They may also present with signs of right-sided heart failure, including raised jugular venous pressure, right upper quadrant pain, and peripheral edema.[4]
- Fulminant - Fulminant myocarditis is defined as ventricular dysfunction and heart failure within 2–3 weeks of infection.[2][17][18][19] The early signs resemble those of sepsis: fever, low pulse pressure, cold extremities, and sinus tachycardia.[4][5]
According to a study, ventricular arrhythmias are also seen in the patients of myocarditis.[20]
Physical Examination
- Patients with [disease name] usually appear [general appearance].
- Physical examination may be remarkable for:
- [finding 1]
- [finding 2]
- [finding 3]
- [finding 4]
- [finding 5]
- [finding 6]
Laboratory Findings
Inflammatory biomarkers
- Elevated levels of inflammatory markers including erythrocyte sedimentation rate, C reactive protein, and procalcitonin are usually seen in myocarditis but they are non-specific and do not confirm the diagnosis. Increases levels of Interleukin-6 (IL-6), d-dimer, serum ferritin, prothrombin time were seen in COVID-19 patients.[21][14]
Cardiac biomarkers
- Levels of cardiac enzymes such as cardiac troponins (cardiac troponin I(cTnI), cardiac troponin T (cTnT)) and natriuretic peptides (N-terminal pro-B-type natriuretic peptide (NT-proBNP), and Brain natriuretic peptide (BNP)) usually are elevated in myocarditis due to acute myocardial injury and possible ventricular dilation.
- Elevations of both troponin and NT-proBNP levels were observed in the COVID-19–related myocarditis cases.[5][6][7][8][17][22]
- Elevated NT-pro-BNP level has been associated with worse clinical outcomes in severe COVID-19 patients.[23][24]
- Cardiac troponins and brain natriuretic peptides are sensitive but non-specific in the diagnosis of myocarditis.[25][26][27]
- Although a negative troponin result cannot exclude myocarditis, negative serial high-sensitivity cardiac troponin (hs-cTn) still is helpful in the acute phase and makes the diagnosis of acute myocarditis significantly less likely.[28]
Electrocardiogram
- ECG is usually abnormal in myocarditis but it is neither sensitive nor specific in the diagnosis.[29][3]
- ECG abnormalities ST-elevation and PR depression may be observed in myocarditis in COVID-19 patients.[6][3][17]
- However, these abnormalities are not sensitive in detecting myocarditis in COVID-19. For example, one COVID-19–related myocarditis case showed neither ST-elevation nor PR depression.[5]
- Other ECG abnormalities, including new-onset bundle branch block, premature ventricular complexes, QT prolongation, and bradyarrhythmia with advanced atrioventricular nodal block, can be observed in myocarditis.[7]
The American Heart Association (AHA) recommends further testing with 1 or more cardiac imaging methods such as an echocardiogram or cardiovascular magnetic resonance (CMR) for patients having signs consistent with myocarditis.[4] However, echocardiogram or cardiac imaging can be avoided or delayed until recovery from COVID-19 in the patients with COVID-19 and myocardial injury who are hemodynamically and electrophysiologically stable with mild to moderate elevations of troponin unless the patient clinically deteriorates and develops hemodynamic instability, shock, ventricular arrhythmias, or a severely elevated or rapidly rising troponins.[30]
Echocardiography
- The prominent signs of myocarditis on an echocardiogram are increased wall thickness, chamber dilation, diffuse hypokinesia/dyskinesia, and pericardial effusion in the background of ventricular systolic dysfunction.[31][32][3]
- These findings were noted in COVID-19 related myocarditis cases.[7][6][5]
Cardiac Magnetic Resonance
- Cardiac Magnetic resonance (CMR) has major imaging advantages with highest diagnostic accuracy over echocardiography[33], but it has limitations of availability, the requirement for some breath-holding, the requirement for deep cleaning after use given the high contagious risk of COVID-19 and slower throughput.
- If CMR is performed, revised Lake Louise consensus criteria are used to interpret the results.[34] 1) edema 2) irreversible cell injury 3) hyperemia or capillary leak.
- In all of the SARS-CoV-2–related myocarditis cases for which CMR results were reported, myocardial edema and/or scarring were observed.[6][7][8]
Cardiac Computed Tomography
- Cardiac Computed Tomography scan (CT scan) with contrast enhancement and ECG gating is an effective alternative to CMR in terms of rapid testing and minimal requirement of breath-holding, especially when the patient has to undergo a high-resolution CT scan (HRCT) of the chest for assessment of acute respiratory distress syndrome.
- Myocardial hypertrophy due to edema was observed in COVID -19 related myocarditis.[7]
Endomyocardial biopsy
- Endomyocardial biopsy (EMB) has been recommended as the definitive diagnostic tool for myocarditis by the American Heart Association (AHA) and European Society of Cardiology (ESC).[35] In non–COVID-19 cases, endomyocardial biopsy has traditionally been recommended in fulminant presentations to exclude the rare presentation of eosinophilic, hypersensitive,and giant-cell myocarditis.[36] However, in COVID-19, it may not be feasible because of the instability of the patient, requirement of expertise, false-negative rate and risk of contagiousness, especially if the biopsy results would not change clinical management.[3][4][33]
- EMB samples if obtained should be tested for inflammatory infiltrates and for the presence of viral genomes by DNA/RNA extraction.[3]
- In a COVID-19 case reported, EMB showed diffuse T-lymphocytic inflammatory infiltrates with huge interstitial edema and no replacement fibrosis, suggesting an acute inflammatory process. SARS-CoV-2 genome was absent within the myocardium in molecular analysis.[8]
Treatment
Medical Therapy
- There is no definitive treatment for COVID-19-related-myocarditis; the mainstay of therapy is supportive care.
- As per AHA recommendations, in the patients of fulminant myocarditis, initial management includes the protocol of cardiogenic shock which is the administration of inotropes and/vasopressors and mechanical ventilation[6][18]; and use of extracorporeal membrane oxygenation(ECMO), ventricular assistive devices (VAD) in severe cases.[5][37][17] This protocol has been the mainstay of treatment in COVID-19-related-myocarditis cases as well and proved beneficial in mitigating ventricular systolic dysfunction.
- Though the ESC did not approve the use of intravenous immunoglobulins (IVIG) and corticosteroids in active-infection myocarditis, COVID-19 related myocarditis cases have been reported in which use of immunoglobulins and corticosteroids have been successful.[18][5][6][22]
- Tocilizumab, an anti–IL-6 receptor monoclonal antibody, is being tested in a randomized controlled trial of COVID-19 patients with raised IL-6 levels.[38] This might be beneficial in the setting of cytokine storm syndrome and help reduce myocardial inflammation.[28]
Surgery
- Surgery is the mainstay of therapy for [disease name].
- [Surgical procedure] in conjunction with [chemotherapy/radiation] is the most common approach to the treatment of [disease name].
- [Surgical procedure] can only be performed for patients with [disease stage] [disease name].
Prevention
- There are no primary preventive measures available for [disease name].
- Effective measures for the primary prevention of [disease name] include [measure1], [measure2], and [measure3].
- Once diagnosed and successfully treated, patients with [disease name] are followed-up every [duration]. Follow-up testing includes [test 1], [test 2], and [test 3].
