Which finding is associated with left-sided heart failure?

• A. Ascites
• B. Pulmonary congestion
• C. Peripheral edema
• D. Liver congestion

Answer: (B)

The main concept is that left-sided heart failure causes a backup of pressure into the lungs, leading to pulmonary congestion. When the left ventricle fails, pressure builds in the left atrium and pulmonary veins, raising hydrostatic pressure in the pulmonary capillaries and causing fluid to leak into the interstitial and alveolar spaces. This results in symptoms like dyspnea and crackles. In contrast, ascites, peripheral edema, and liver congestion arise from systemic venous congestion seen with right-sided (or combined) heart failure, where blood backs up into the liver and peripheral tissues. So pulmonary congestion is the finding associated with left-sided failure.
