Which symptom is commonly associated with congestive heart failure?

Shortness of breath is a primary symptom associated with congestive heart failure (CHF) because this condition leads to a buildup of fluid in the lungs, a situation known as pulmonary congestion. When the heart is unable to pump blood effectively, increased pressure in the blood vessels of the lungs occurs, causing fluid to leak into the lung tissue. This results in difficulty breathing, especially during physical activity or when lying down, leading to episodes of increased shortness of breath or orthopnea.

Recognizing shortness of breath as a key symptom is crucial for early diagnosis and management of congestive heart failure, as it often prompts patients to seek medical attention. Other symptoms associated with CHF may include fatigue, swelling in the legs and ankles, and rapid heartbeat; however, shortness of breath often stands out and can significantly impact a patient's quality of life.
