This condition is a type of circulatory shock and is often a result of severe myocardial infarction (heart attack), but it can also be caused by other cardiac conditions such as cardiomyopathy, valvular heart disease, and severe arrhythmias.

Pathophysiology[edit]

Cardiogenic shock occurs when the heart's pumping function is severely impaired. This impairment can be due to:

  • Myocardial infarction: Damage to the heart muscle reduces its ability to contract.
  • Cardiomyopathy: Diseases of the heart muscle that affect its ability to pump blood.
  • Valvular heart disease: Dysfunction of the heart valves can lead to inadequate blood flow.
  • Arrhythmias: Abnormal heart rhythms can disrupt the heart's ability to pump effectively.

The reduced cardiac output leads to decreased perfusion of vital organs, resulting in symptoms such as hypotension, tachycardia, oliguria, and altered mental status.

Symptoms[edit]

The symptoms of cardiogenic shock include:

Diagnosis[edit]

Diagnosis of cardiogenic shock is based on clinical presentation and diagnostic tests, including:

Treatment[edit]

The treatment of cardiogenic shock aims to improve cardiac output and tissue perfusion. It includes:

Prognosis[edit]

The prognosis of cardiogenic shock depends on the underlying cause and the timeliness of treatment. Despite advances in medical care, cardiogenic shock remains a serious condition with a high mortality rate.
