Overview

Historical Perspective

  • COVID-19-associated stress cardiomyopathy was first described by Elena Roca, an Italian physician, in April 2020.[1]

Classification

  • There is no established system for the classification of COVID-19-associated stress cardiomyopathy.

Pathophysiology

  • It is thought that COVID-19-associated stress cardiomyopathy is the result of extreme sympathetic stimulation due to abnormal release of catecholamines causing epicardial coronary vasospasm.
  • Many mechanisms occurring in COVID-19 patients may lead to myocardial injury and left ventricular dysfunction.[2]
  • One of the proposed theory is that patients may experience stress-induced adrenergic discharge as consequence of fever and inflammatory response to infection. One other factor to consider is the direct SARS-CoV-2 injury causing endothelial dysfunction, which may cause microvascular vasoconstriction that can manifest in a transient left ventricular apical dysfunction, (apical ballooning).[3]
  • Proposed mechanisms that have the potential to cause myocardial injury in acute coronavirus disease 2019 cardiovascular syndrome:[4]

Causes

  • COVID-19-associated stress cardiomyopathy may be caused by a very intense sympathetic stimulation which is theorized to be caused either due to direct viral action or the ongoing psychological, economical and social effects (physical distancing rules, lack of social interaction) of the pandemic due to the imposed quarantine.[3]

Differentiating COVID-19-associated stress cardiomyopathy from other Diseases

  • COVID-19-associated stress cardiomyopathy must be differentiated from other diseases that cause left ventricular dysfunction such as acute myocardial infarction (STEMI and NSTEMI) and viral myocarditis.

Epidemiology and Demographics

  • The incidence of COVID-19-associated stress cardiomyopathy is approximately 7.8% of all patients presenting acute coronary syndrome.[3]
  • In comparison, the stress cardiomyopathy incidence in the pre-COVID-19 period was varying between 1.5-1.8%.[3]

Risk Factors

  • There are no established risk factors for COVID-19-associated stress cardiomyopathy.
  • Hypertension was, however, the most frequently comorbidity found across the groups in the COVID-19 period patients, as was hyperlipidemia.[3]

Screening

  • There is insufficient evidence to recommend routine screening for COVID-19-associated stress cardiomyopathy.

Natural History, Complications, and Prognosis

  • A study evaluated the outcomes for patients with stress cardiomyopathy. COVID-19-associated stress cardiomyopathy outcomes were similar to the stress cardiomyopathy not related to COVID-19 with regard to mortality and 30-day rehospitalization.[3]
  • The same study showed that COVID-19-associated stress cardiomyopathy patients had a significantly longer hospital length of stay. in comparison to the ones not related to COVID-19.[3]
  • Provided that patients survive the initial insult without any complications, most patients recover and have a normalized cardiac function within a few weeks.[5][6][7]

Diagnosis

Diagnostic Study of Choice

History and Symptoms

Symptoms of stress cardiomyopathy can mimic acute coronary syndrome. The most common presenting symptoms are:[20][21][22][23][24][25]

When taking the history from a patient with suspected stress cardiomyopathy, it is important to ask about:[21][23]

Physical Examination

Organ System Findings Suggestive Of
General appearance Patient may be anxious, ill-appearing or diaphoretic
Vital signs Cardiogenic shock
Cardiac Murmurs, S3, gallop rhythm, displaced PMI Heart failure
Respiratory Rales, crackles Pulmonary edema

Laboratory Findings

  • Laboratory findings consistent with the diagnosis of COVID-19-associated stress cardiomyopathy include elevated troponin and Pro-BNP.[3]
  • Elevated levels of serum catecholamines may also be found in patients with stress cardiomyopathy.[37][38][39][40]

Electrocardiogram

The ECG findings are largely the same of the regular stress cardiomyopathy, and are often confused with those of an acute anterior wall myocardial infarction.[41][42] Findings on ECG include:[42][43][44][45][46][47][48]

X-ray

Takotsubo in Japanese language refer to a ceramic pot, which is used to trap octopus. The typical chest x-ray findings in patients with stress cardiomyopathy include a takotsubo-shaped heart, in which there is apical ballooning and narrowing of the proximal portion near the great vessels.

Echocardiography or Ultrasound

The following echocardiographic findings may be seen in patients with stress cardiomyopathy:[49][50][51][52]

CT scan

A cardiac CT scan can also help differentiate between stress cardiomyopathy and acute MI. Regional abnormalities in the wall motion of the heart, along with absence of coronary atherosclerosis support the diagnosis of stress cardiomyopathy over an acute MI.[12]

MRI

Other findings on CMR include:[64][65]

Other Imaging Findings

Positron Emission Tomography (PET) Scan

In patients with stress cardiomyopathy, a PET scan may be done. Areas of hypokinesia or dyskinesia have reduced glucose utilization compared to normal regions.[66]

Coronary Angiography

Other Diagnostic Studies

Cardiac Catheterization

When patients with stress cardiomyopathy undergo cardiac catheterization, the following findings are usually reported:[70][71][72]

Myocardial Biopsy

  • The combination of inflammatory changes and contraction bands distinguish stress cardiomyopathy from coagulative necrosis seen in MI.[73]

Treatment

Medical Therapy

  • There is no treatment for specific treatment for stress cardiomyopathy when associated with COVID-19. The mainstay of therapy is supportive care, which is the same for the stress cardiomyopathy not related to COVID-19..
  • Medical therapy in patients with stress cardiomyopathy is mostly targeted towards the treatment of complications. For stress cardiomyopathy per se, the use of heparin and aspirin are controversial. It must be noted that the use of beta blockers alone is not advised, as this will result unopposed activity of catecholamines at the alpha receptors and can cause further prolongation of the QT interval. The combined use of alpha- and beta blockers is reasonable.[74]

Treatment of Complications

The following interventions are performed if their associated complications arise:[74][75][76]

Surgery

  • Surgical intervention is not recommended for the management of COVID-19-associated stress cardiomyopathy.

Primary Prevention

  • There are no established measures for the primary prevention of COVID-19-associated stress cardiomyopathy if a patient has acquired COVID-19 infection.
  • Preventive measures should be taken to avoid COVID-19 infection.

Secondary Prevention

  • There are no established measures for the secondary prevention of COVID-19-associated stress cardiomyopathy.
