Which finding is most associated with left-sided heart failure?

• A. Peripheral edema
• B. Ascites
• C. Elevated JVD
• D. Dyspnea

Answer: (D)

Left-sided heart failure causes pressure to back up into the lungs, leading to pulmonary congestion. This results in dyspnea because fluid in the lungs makes it harder to oxygenate blood and catch one’s breath, especially with exertion or when lying down. Dyspnea is the hallmark symptom of left-sided failure due to this pulmonary edema. The other findings reflect systemic venous congestion more typical of right-sided failure (or biventricular failure): peripheral edema, ascites, and elevated neck venous pressure. They arise from backup of blood into the body’s venous system rather than the lungs, so they’re less specific for left-sided involvement.
