ANNOUNCER: One common symptom of heart failure is edema which is swelling in the body due to fluid buildup. Swelling can occur in the ankles, legs and lower back.
JACQUELINE NOONAN, MD: Swollen ankles are common. They're common in the summertime, they're common when you sit with your legs down, if you've been on an airplane. They also can occur in heart failure, but the fact that you have swollen ankles does not necessarily or probably very often really mean that you have heart failure.
