Understanding Pediatric Cardiogenic Shock

What is pediatric cardiogenic shock?

Pediatric cardiogenic shock happens when a child's heart cannot pump enough blood to the body. As a result, organs and tissues may not get the oxygen and nutrients they need.

Cardiogenic shock is rare, but it is a very serious complication of heart disease in children. It can occur in children with:

• Congenital heart disease
• Heart muscle disease
• Myocarditis
• Heart failure
• Other cardiac conditions

A child's condition can change quickly. Early recognition, close monitoring and timely treatment are critical.

What are signs and symptoms of pediatric cardiogenic shock?

Every child is different. Symptoms may vary depending on age and the underlying heart condition.

Signs that may signal your child needs immediate medical attention include:

• Cool, pale or clammy hands and feet
• Fast heartbeat
• Fast or difficult breathing
• Extreme tiredness or sleepiness
• Irritability or difficulty waking up
• Dizziness or fainting
• Reduced urine output or fewer wet diapers
• Poor feeding in infants
• Confusion or trouble staying alert
• Swelling in the legs, feet, abdomen or around the eyes

If your child has a heart condition and develops symptoms that concern you, contact your healthcare team promptly.

Call 911 right away if your child:

• Has severe symptoms
• Gets worse quickly
• Has trouble breathing
• Has trouble staying awake
• Becomes unresponsive or collapses

What causes pediatric cardiogenic shock?

Cardiogenic shock happens when the heart becomes too weak or damaged to pump enough blood through the body.

Potential causes include:

• Congenital heart disease
• Heart muscle disease (cardiomyopathy)
• Inflammation of the heart muscle (myocarditis)
• Acute or worsening heart failure
• Serious heart rhythm problems (arrhythmias)
• Problems after heart surgery
• Other rare heart conditions

Not every child with these conditions will experience cardiogenic shock. Working closely with your child’s care team can help you understand your child’s risks and know which warning signs to watch for.

How is pediatric cardiogenic shock diagnosed?

There is no single test that can diagnose pediatric cardiogenic shock. Healthcare professionals consider your child’s symptoms, physical exam, test results and heart imaging to understand what is happening and decide on treatment.

Your child’s care team may use:

• Blood pressure and oxygen monitoring
• Blood tests
• Heart ultrasound (echocardiography)
• EKG (electrocardiogram)
• Other imaging or testing when needed

Cardiogenic shock can get worse quickly. Healthcare teams often reassess children to guide treatment decisions and monitor recovery.

How is pediatric cardiogenic shock treated?

Treatment depends on what caused the shock and how sick the child is. Children with cardiogenic shock are usually treated in a hospital, often in a pediatric ICU.

Treatment may include:

• Medications that help the heart pump more effectively
• Medications that support blood pressure and circulation
• Oxygen or breathing support
• Treatment of the underlying heart condition
• Close monitoring of heart and organ function
• Devices that help the heart pump blood when needed

Treatment focuses on improving blood flow, supporting the body’s organs and treating the cause of the shock.

What complications can occur?

When organs do not get enough blood flow and oxygen, serious problems can develop. These may include:

• Kidney injury
• Liver injury
• Difficulty breathing that may require a ventilator (breathing machine)
• Cardiac arrest (when the heart suddenly stops beating)
• Need for mechanical circulatory support, such as a heart pump device
• Death

Early treatment can help lower the risk of these complications.

What can families expect after recovery?

Recovery is different for every child. It depends on the heart condition, how sick the child was and their overall health.

Many children improve with appropriate treatment and continued follow-up care. Some children may need ongoing support from a pediatric cardiologist and other specialists.

Follow-up care may include:

• Regular cardiology visits
• Imaging and heart function testing
• Medication management
• Monitoring for changes in symptoms
• Planning for future care needs as your child grows

Your child's healthcare team can help guide decisions, answer questions and support your family through recovery.

Talking with your child’s care team

When a child has cardiogenic shock, families often have questions. Consider asking:

• What caused my child’s cardiogenic shock?
• What warning signs should I watch for at home?
• What symptoms should prompt me to call the care team?
• When should I seek emergency care?
• Will my child need more testing or medications?
• What activities are safe during recovery?
• What follow-up care will my child need?

You do not have to navigate this alone

A diagnosis of pediatric cardiogenic shock can be frightening and overwhelming for families. It is normal to have questions and concerns along the way.

Your child’s care team can help guide you through treatment decisions, recovery and follow-up. You can support your child’s heart health by:

• Learning which signs and symptoms to watch for
• Knowing when to call the healthcare team
• Knowing when to seek emergency care
• Staying connected to trusted sources of support and information

Support from the American Heart Association

The American Heart Association helps families understand pediatric heart conditions and find trusted information and support. By working with your child’s healthcare team, you can make decisions and get the care your child needs.
