In heart failure, which symptom is commonly associated with history?

• A. Chest pain with exertion
• B. Shortness of breath on exertion and leg swelling
• C. Palpitations without dyspnea
• D. Sudden severe hypertension

Answer: (B)

The main idea is that heart failure often shows up in history as signs of fluid overload and reduced cardiac output, especially exertional shortness of breath with leg swelling. When the heart's pumping ability declines, blood can back up into the lungs, causing dyspnea with activity as oxygen exchange becomes less efficient. At the same time, increased venous pressure pushes fluid into the extremities, leading to leg swelling and edema. This combo—shortness of breath on exertion plus peripheral edema—is a classic historical clue for chronic heart failure. Chest pain with exertion points more toward coronary ischemia, where reduced blood flow triggers angina during activity. Palpitations without dyspnea can occur with arrhythmias but aren’t the defining history of heart failure. Sudden severe hypertension is not a typical historical feature of heart failure itself and would suggest a hypertensive crisis instead.
