What Are the Signs and Symptoms of Heart Failure?

The most common signs and symptoms of heart failure are:

  • Shortness of breath or trouble breathing
  • Fatigue (tiredness)
  • Swelling in the ankles, feet, legs, abdomen, and veins in the neck

All of these symptoms are the result of fluid buildup in your body. When symptoms start, you may feel tired and short of breath after routine physical effort, like climbing stairs.

As your heart grows weaker, symptoms get worse. You may begin to feel tired and short of breath after getting dressed or walking across the room. Some people have shortness of breath while lying flat.

Fluid buildup from heart failure also causes weight gain, frequent urination, and a cough that's worse at night and when you're lying down. This cough may be a sign of acute pulmonary edema (e-DE-ma). This is a condition in which too much fluid builds up in your lungs. The condition requires emergency treatment.
