*Patients with chronic heart failure (HF) may be at higher risk of developing severe COVID-19 infection due to the advanced age and the presence of multiple comorbidities.
*Both de novo acute heart failure and acute decompensation of chronic heart failure can occur in patients with COVID-19.
*Presumed pathophysiologic mechanisms for the development of new or worsening heart failure in patients with COVID-19 include:<ref name="pmid32219357">{{Cite pmid|32219357}}</ref> <ref name="pmid32360242">{{Cite pmid|32360242}}</ref> <ref name="pmid32186331">{{Cite pmid|32186331}}</ref> <ref name="pmid30625066">{{Cite pmid|30625066}}</ref> <ref name="pmid32140732">{{Cite pmid|32140732}}</ref>   
**Acute exacerbation of chronic heart failure
**Acute myocardial injury (which in turn can be caused by several mechanisms)
**Stress cardiomyopathy (i.e., Takotsubo cardiomyopathy)
**Impaired myocardial relaxation resulting in diastolic dysfunction [i.e., Heart failure with preserved ejection fraction (HFpEF)]
**Right-sided heart failure, secondary to pulmonary hypertension caused by hypoxia and acute respiratory distress syndrome (ARDS)

Echocardiography

  • A complete standard transthoracic (TTE) has not been recommended in COVID-19 patients considering the limited personal protective equipment (PPE) and the risk of exposure of additional health care personnel.[6]

    • However, increased natriuretic peptide levels are frequently seen among patients with severe inflammatory or respiratory diseases.[11] [12] [13] [14] [15]
    • Therefore, routine measurement of BNP/NT-proBNP has not been recommended in COVID-19 patients, unless there is a high suspicion of HF based on clinical grounds.


Treatment

Medical Therapy

  • Patients with chronic heart failure are recommended to continue their previous guideline-directed medical therapy, including beta-blockers, ACEI or ARB, and mineralocorticoid receptor antagonists. [16]
  • Acute heart failure in the setting of COVID-19 is generally treated similarly to acute heart failure in other settings. These may include:
    • Fluid restriction
    • Diuretic therapy
    • Vasopressors and/or inotropes
    • Ventricular assisted devices and extracorporeal membrane oxygenation (ECMO)
  • Beta-blockers should not be initiated during the acute stage due to their negative inotropic effects.[17]
  • Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) should be used with caution in patients with acute heart failure due to their effect on fluid and sodium retention.[18]
