What is one common symptom of congestive heart failure?

Shortness of breath is a common symptom of congestive heart failure due to the heart's impaired ability to pump blood effectively. When the heart cannot maintain adequate blood flow, fluid can accumulate in the lungs, leading to pulmonary congestion. This fluid buildup causes difficulty in breathing, particularly during physical activity or when lying down, known as orthopnea. Patients may also experience episodes of shortness of breath at night, referred to as paroxysmal nocturnal dyspnea. This symptom is a crucial indicator of heart failure and helps healthcare providers assess the severity of the condition.
