Overview
COVID-19 is caused by the novel coronavirus, also known as SARS-CoV-2. It mainly affects the lungs, causing severe acute respiratory syndrome. It invades through the Angiotensin-converting enzyme 2 (ACE2) receptors present abundantly not only in the lungs but also in the heart, kidneys, intestine, brain, skin thus causing multiorgan dysfunction. 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.

Historical Perspective
- The novel coronavirus, SARS-CoV-2, is identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China in late December 2019. SARS-CoV-2 has rapidly spread across China and in other countries, raising major global concerns. This novel coronavirus, SARS-CoV-2, was named the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) for it similarity severe acute respiratory syndrome related coronaviruses such as SARS-CoV, which caused acute respiratory distress syndrome (ARDS) in 2002–2003.[1][2][3][4][5]
- On January 30, 2020,the World Health Organization(WHO) declared the outbreak as a Public Health Emergency of International Concern.[6]
- On March 12, 2020, the World Health Organization declared the COVID-19 outbreak a pandemic.[7]
Classification
- There is no established system for the classification of the myocarditis seen in COVID-19.
- For general classification of myocarditis, click here.
Pathophysiology
- Myocarditis is an inflammatory disease of the heart characterized by inflammatory infiltrates and myocardial injury without an ischemic cause.[8]
- The major cause of myocarditis in the United States and other developed countries is viral.[9] [10]
- The exact mechanisms of COVID-19 induced myocarditis are not yet well known, although several have been proposed based on the limited data outside of case reports.
Proposed pathophysiologies of SARS-CoV-2 myocarditis
- Direct invasion of the virus into cardiomyocytes:
- SARS-CoV-2 infection is caused by receptor-mediated endocytosis via binding of the viral surface spike protein (primed by TMPRSS2 - Transmembrane Protease Serine 2) to the human angiotensin-converting enzyme 2 (ACE2) receptor.[11][12]
- ACE2 is expressed in the lung, principally type II alveolar cells which appears to be the principal portal of entry.[13]
- ACE2 is highly expressed in the heart as well.[14]
- Although, there are limited reports showing pathological evidence that COVID-19 directly invades the heart.[15]
- Hyperinflammation and Cytokine storm
- Naive T lymphocytes can be primed for viral antigens via antigen-presenting cells.[16]
- The primed CD8+ T lymphocytes migrate to the cardiomyocytes and through cell-mediated cytotoxicity, cause myocardial inflammation and cardio-tropism by heart-produced Hepatocyte Growth Factor (HGF) which interacts with c-Met, an HGF receptor on naïve T lymphocytes.[16]
- 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.[17]
- Cytokine storms result in increased vascular wall permeabilityand myocardial edema.[18][19]
- A positive feedback loop of immune activation and myocardial damage is established.[20][8]
- Thus cytokine storm activated by T helper cells (Th1 and Th2) and a systemic hyperinflammatory response is triggered.[21][22]
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.
- Interstitial mononuclear inflammatory infiltration has been observed in the heart tissue in COVID-19 autopsy studies.[23]
- In one of the autopsy studies of myocarditis in COVID-19, the viral particles were observed in interstitial cytopathic macrophages. Cardiac myocytes showed non‐specific features consisting of focal myofibrillar lysis, and lipid droplets but no viral particles in myocytes and endothelia; small intramural vessels were free from vasculitis and thrombosis.[15]
Causes
Myocarditis in COVID-19 is caused by:
- Direct invasion of endothelial cells by SARS-CoV-2
- Pro-inflammatory cytokine storm
Differentiating COVID-19 associated myocarditis from other Diseases
Myocarditis in COVID-19 must be differentiated from other diseases that cause chest pain, dyspnea, elevated cardiac biomarkers, ventricular dysfunction, such as:
- Acute Coronary Syndrome
- Stress-induced cardiomyopathy (Takotsubo cardiomyopathy)
- Heart failure
Epidemiology and Demographics
- The prevalence of cardiovascular disease among patients with COVID-19 is high, and >7% of patients experience myocardial injury from the infection.[25]
- The overall incidence of acute cardiac injury caused by COVID-19 ranges from 7 to 28% among hospitalized patients.[26][27][28]
- The prevalence of myocarditis among COVID-19 patients has not yet been reported. Though many anecdotal reports of myocarditis have been noted, there are only a few case reports of myocarditis related to COVID-19 .[27][19][29][18][30][31][15][32][33]
- Myocarditis has also been reported as the cause of death in some COVID-19 patients.[34]
Age
- COVID-19-associated myocarditis is more commonly observed among elderly patients.[27][28]
Gender
- There is no data on gender predilection to myocarditis in COVID-19.
Race
- There is no data on racial predilection to myocarditis in COVID-19.
Risk Factors
- There are no established risk factors for myocarditis.
- But the prevalance of COVID-19-associated myocarditis has been more in elderly patients [age>50] and patients with pre-existing cardiovascular diseases.[28][27]
Screening
There is insufficient evidence to recommend routine screening for myocarditis in COVID-19 patients.
Natural History, Complications and Prognosis
Natural history
If left untreated, myocarditis of patients with COVID-19 may progress to develop cardiogenic shock, heart failure, and succumb to death.[32]
Complications
Common complications of [myocarditis] include:
- Dilated cardiomyopathy
- Acute-onset heart failure
- Pericarditis
- Ventricular dysfunction
- Arrhythmias
- Sudden cardiac death
Prognosis
- Prognosis is generally poor.
- A retrospective analysis of the cause of death in Chinese patients infected with COVID-19 revealed that 40% of patients died at least in part because of myocardial injury and circulatory collapse.[34]
- In another study, patients hospitalized for COVID-19 infection developed cardiac injury in roughly 20% of cases; thus leading to greater than 50% mortality.[27]
Diagnosis
Diagnostic Criteria
- The diagnosis of myocarditis cannot be made with a single test or examination. When indicated, the diagnosis requires a combination of:
Signs and Symptoms
Clinical presentations have varied in the reported COVID-19 cases with myocarditis in the literature with a potential overlap in symptomatology in patients with primary COVID-19 infection and COVID-19 patients with clinically suspected myocarditis. Clinical presentation of SARS-CoV-2 myocarditis varies among cases from mild to severe to fulminant.
- Mild - fatigue and dyspnea,[29][18], chest pain or chest tightness on exertion.[19][30]
- Severe - Many patients deteriorate and show symptoms of tachycardia and acute-onset heart failure with cardiogenic shock.[19][29][18] They may also present with signs of right-sided heart failure, including raised jugular venous pressure, right upper quadrant pain, and peripheral edema.[10]
- Fulminant - Fulminant myocarditis is defined as ventricular dysfunction and heart failure within 2–3 weeks of infection.[8][35][31][36] The early signs resemble those of sepsis: fever, low pulse pressure, cold extremities, and sinus tachycardia.[10][19]
According to a study, ventricular arrhythmias are also seen in the patients of myocarditis.[37]
Physical Examination
- Physical examination of patients with severe myocarditis may be remarkable for:
- Physical examination of patients with fulminant myocarditis may be remarkable for:
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 not 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.[27][17]
Cardiac biomarkers
- Levels of cardiac enzymes such as cardiac troponins (cardiac troponin I(cTnI) and 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.[19][29][18][30][35][38]
- Elevated NT-proBNP level has been associated with worse clinical outcomes in severe COVID-19 patients.[39][40]
- Cardiac troponins and brain natriuretic peptides are sensitive but not specific in the diagnosis of myocarditis. It requires other supplementary findings and investigations.[41][42][43]
- 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.[44]
Electrocardiogram
- ECG is usually abnormal in myocarditis but it is neither sensitive nor specific in the diagnosis.[45][9]
- ECG abnormalities ST-elevation and PR depression may be observed in myocarditis in COVID-19 patients.[29][9][35]
- 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.[19]
- 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.[18]
The American Heart Association (AHA) recommends further testing with 1 or more cardiac imaging methods such as an echocardiogram or cardiovascular magnetic resonance imaging (CMR) for patients having signs consistent with myocarditis.[10] 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 troponin levels.[46]
Echocardiography
- The prominent signs of myocarditis on an echocardiogram are increased wall thickness, ventricular dilation, diffuse hypokinesia/dyskinesia, and pericardial effusion in the background of ventricular systolic dysfunction.[47][48][9]
- These findings were noted in COVID-19 related myocarditis cases.[18][29][19]
Cardiac Magnetic Resonance
- Cardiac Magnetic Resonance (CMR) imaging is a vital test in the diagnosis of myocarditis, especially if an endomyocardial biopsy (EMB) is not pursued or cannot be obtained, before the COVID-19 pandemic.[49]
- Cardiac Magnetic resonance (CMR) has major imaging advantages with highest diagnostic accuracy over echocardiography.[50]
- CMR is not indicated in unstable patients who present with severe heart failure, circulatory shock, ventricular arrhythmia, or high-grade AV block and an EMB should be obtained.[51]
- CMR using the revised Lake Louise consensus criteria to interpret the results has a specificity of up to 91% and a sensitivity of 67% for diagnosing myocarditis.[51] 1) edema 2) irreversible cell injury 3) hyperemia or capillary leak.
- If available and there are no contraindications, CMR can safely be used as a first-line diagnostic tool in myocarditis associated with COVID-19.[52]
- In all of the SARS-CoV-2–related myocarditis cases for which CMR results were reported, myocardial edema and/or scarring were observed.[29][18][30][32][38][33]
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.[18]
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).[53]
- 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.[54]
- 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.[9][10][50]
- EMB samples if obtained should be tested for inflammatory infiltrates and for the presence of viral genomes by DNA/RNA extraction.[9]
- 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.[30]
Treatment
Medical Therapy
- There is no definitive treatment for COVID-19-assocaited myocarditis; the mainstay of therapy is supportive care because no specific effective antiviral therapies have been identified.
- 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[29][31]; and use of extracorporeal membrane oxygenation(ECMO), ventricular assistive devices (VAD) in severe cases.[19][55][35] This protocol has been the mainstay of treatment in COVID-19-associated myocarditis cases as well and proved beneficial in mitigating ventricular systolic dysfunction.
- Though the European society of Cardiology (ESC) did not approve the use of intravenous immunoglobulins (IVIG) and corticosteroids in active-infection myocarditis, COVID-19-associated myocarditis cases have been reported in which use of immunoglobulins and corticosteroids have been beneficial.[31][19][29][38]
- 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.[56] This might be beneficial in the setting of cytokine storm syndrome and help reduce myocardial inflammation.[44]
Prevention
- There are no primary preventive measures available for COVID-19-associated myocarditis.
- For effective measures for the primary prevention of [COVID-19], refer to COVID-19 primary prevention.
