Overview

In Italy, for the first time in a 69-year-old patient, who was presented with cardiogenic shock due to COVID-19 infection myocardial involvement by viral particles was pathologically proved through biopsy. Two mechanisms are more probable to contribute to cardiogenic shock related to Covid-19 that includes direct invasion and cytokine storm. According to a recent study, one-third of critically ill patients with COVID-19 of an ICU in Washington State had clinical signs of cardiogenic shock and cardiomyopathy. According to an observational study in China, COVID-19 associated cardiogenic shock has a poor prognosis.

Historical Perspective

  • In December 2019, a novel coronavirus named SARS-CoV-2 resulted in Coronavirus disease 2019, which caused respiratory disease outbreak identified firstly in Wuhan, China.[1][2]
  • On March 12, 2020, the WHO declared coronavirus disease 2019(COVID-19) outbreak to be a pandemic.[3]
  • In Italy, for the first time in a 69-year-old patient, who was presented with cardiogenic shock due to COVID-19 infection, myocardial involvement by viral particles was pathologically proved through biopsy. [4]

Classification

Pathophysiology

Two mechanisms are more probable to contribute to cardiogenic shock related to Covid-19:[5] [6]

Causes

The causes of cardiogenic shock related to COVID-19 might include: [7] [8]

Differentiating COVID-19 associated cardiogenic shock from other Diseases

Cardiogenic shock related to COVID-19 must be differentiated from other diseases which include: [9] [10]

Some hemodynamic parameters would help differentiate significant types of shock: [11]

Cardiac Output Pulmonary Capillary Wedge Pressure Systemic Vascular Resistance Pulmonary artery diastolic pressure SVO2
COVID-19-associated cardiogenic shock ↑↔
Septic shock
Hypovolemic shock

Natural History, Complications and Prognosis

Diagnosis

Diagnostic Study of Choice

History and Symptoms:

  • A 69-year-old patient from Italy has been reported by Tavazzi et al., as a cardiogenic shock-associated COVID-19 case.
  • The patient had flu-like symptoms when he was hospitalized and quickly deteriorated into respiratory distress and cardiogenic shock. [4]
  • Four patients with cardiogenic shock complication related to COVID-19 were reported by Sanchez-Recalde, et al.
  • They were hospitalized between 1 March and 15 April 2020 including:[13]

Physical Examination

Physical examination may be remarkable for Covid-19 associated cardiogenic shock:[16]

Laboratory Findings

  • The increase of some biomarkers demonstrates poor prognosis, increased mortality, and more severe symptoms in COVID-19 patients:[18]

Electrocardiogram

X-ray

Echocardiography or Ultrasound

CT scan

  • Generally, the CT scan is not suggested being a primary imaging study, for evaluating a case with cardiogenic shock related to COVID-19. However, it can be suggestive of a coexisting ARDS by demonstrating a ground-glass opacity.[20]

MRI

Treatment

Cardiogenic shock medical therapy:

Mechanical Support:

  • In treating patients with cardiogenic shock related to COVID-19, the efficacy of extracorporeal membrane oxygenation (ECMO) is indistinct.
  • It might be used in most critically ill and highly selective patients.
  • Although specialists implicate ECMO and mechanical circulatory support devices in severe patients with cardiogenic shock related to COVID-19, most of these cases die.
  • It has been reported in a case series from China that most of these patients had a poor prognosis and did not survive despite implicating ECMO. [22] [14]
