Which symptom is NOT part of the typical left-sided heart failure symptom cluster?

• A. Dyspnea
• B. Orthopnea
• C. Peripheral edema
• D. Pulmonary crackles

Answer: (C)

Left-sided heart failure primarily causes fluid to back up into the lungs, leading to pulmonary symptoms. You’ll see dyspnea, especially with activity or lying flat (orthopnea), paroxysmal nocturnal dyspnea, and pulmonary crackles or a cough from interstitial and alveolar fluid. Peripheral edema, on the other hand, comes from systemic venous congestion and is a hallmark of right-sided heart failure (or progression to bi-ventricular failure). So, while left-sided failure focuses on the lungs, peripheral edema is not part of the typical left-sided symptom cluster.
