What is sudden heart failure?
Sudden heart failure occurs when heart failure gets worse very quickly. Your heart suddenly cannot pump as much blood as your body needs. Sudden heart failure causes rapid fluid buildup, or congestion, in the lungs and other parts of the body.
Sudden heart failure is an emergency. You need care right away.
Sudden heart failure is also called a "flare-up" or "acute heart failure."
What are the symptoms of sudden heart failure?
Symptoms of sudden heart failure include:
- Severe trouble breathing.
- Coughing up pink, foamy mucus.
- A new irregular or rapid heartbeat.
