In left-sided heart failure, which finding is least likely to be prominent?

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

Answer: (D)

In left-sided heart failure, the problem is backward flow into the lungs, causing pulmonary venous congestion and fluid to accumulate in the lungs. That produces signs like crackles on auscultation, shortness of breath (dyspnea), and orthopnea. Peripheral edema, on the other hand, comes from systemic venous congestion and is more typical of right-sided heart failure or advanced bi-ventricular failure. So the finding least likely to be prominent with left-sided failure is peripheral edema, since the early and dominant issue is pulmonary rather than peripheral edema. If edema is clearly present, consider right-sided involvement or progression to combined heart failure.
