Cardiac Tamponade: Symptoms & Causes

Overview

• Cardiac Tamponade: A medical emergency characterized by excess fluid in the pericardial sac around the heart, preventing it from pumping blood effectively.
  • Treatment involves fluid removal via needle or surgery for a good outcome.

What is Cardiac Tamponade?

• Occurs when fluid around the heart increases pressure, impeding heart function.
• Results in dropped blood pressure and potential rapid heartbeat (>100 bpm).
• Causes include cancer, infections, trauma, and certain diseases.

Pathophysiology

• The pericardium is a sac with two layers containing pericardial fluid to stabilize the heart.
• Cardiac tamponade occurs when the sac fills with fluid, limiting heart expansion and function.

Relation to Pericardial Effusion

• Pericardial Effusion: Fluid accumulation in the pericardium. Not always symptomatic unless it leads to tamponade.
• Fluid can be blood, discharge, or blood component products.

Prevalence

• Affects people of all ages.
• Occurs in approximately 2 out of every 10,000 people.

Symptoms

• Rapid onset symptoms include:
  • Sharp chest pain radiating to arms, back, neck, or shoulder.
  • Breathing difficulties, lightheadedness, dizziness, altered mental status.
  • Skin color changes (pale, gray, blue), heart palpitations, fast pulse.
• Gradual onset symptoms include:
  • Shortness of breath, abdominal or leg swelling.
  • Fatigue, chest discomfort which eases when leaning forward.

Causes

• Trauma (blunt or penetrating), aortic dissection, cancer, heart attack, infections (e.g., tuberculosis), chronic immune diseases (e.g., lupus, rheumatoid arthritis).
• Medical procedures can also induce tamponade.

Risk Factors

• Congestive heart failure, heart surgery, HIV, kidney disease, autoimmune diseases, cancer, tuberculosis.

Complications

• Cardiogenic shock, heart failure, death.

Diagnosis and Tests

• Physical exams include pulse, blood pressure, heartbeat, and breathing checks.
• Beck’s triad (low blood pressure, bulging neck veins, muffled heart sounds) is a key diagnostic indicator.
• Diagnostic tests include echocardiogram, chest X-ray, CT scan, EKG, heart catheterization.

Management and Treatment

• Pericardiocentesis: Needle procedure to remove fluid.
• Surgery for injuries or when a needle cannot access fluid.
  • Emergency thoracotomy may be necessary if heart stops.
• Address underlying causes with medications like antibiotics or pain relievers.

Treatment Complications

• Possible side effects include bleeding, heart or vessel injuries, collapsed lung, pneumopericardium, heart attack, pulmonary edema, infection, arrhythmias, or organ injury.

Prevention

• Difficult to predict or prevent without early detection, particularly of pericardial effusion.

Prognosis

• Requires rapid treatment for a favorable outcome.
• Delayed treatment results in poorer prognosis.

Living With Cardiac Tamponade

• Follow-up care and medications are crucial.
• Regular echocardiograms and consultations with a cardiologist are recommended.
• Immediate medical attention is required for returning symptoms or signs of infection post-procedure.

Questions for Healthcare Provider

• Frequency of future echocardiograms.
• Chances of recurrence.
• Understanding causes for personal cardiac tamponade event.

Cleveland Clinic Care

• Offers specialized treatment for pericardial diseases with a focus on both acute and chronic conditions.
• Encourages management of mental health during recovery.
