Which of the following is NOT a common symptom of heart failure?

Fatigue is a common symptom of heart failure, often resulting from the body's decreased ability to pump blood effectively, leading to insufficient oxygen and nutrients being delivered to tissues. Swelling in the legs, also known as peripheral edema, occurs due to fluid retention caused by the heart's inability to manage blood volume efficiently. Shortness of breath, or dyspnea, is frequently observed in heart failure, especially during exertion or when lying flat, as fluid builds up in the lungs.

Chest pain, while it can occur, is not a typical symptom specifically associated with heart failure. Instead, chest pain is more commonly linked to conditions such as angina or myocardial infarction (heart attack). In heart failure, the symptoms are primarily related to fluid overload and inadequate perfusion, which do not typically include chest pain as a defining characteristic. Thus, the absence of chest pain as a main symptom of heart failure makes it the correct choice in this context.
