Pulmonary edema is often associated with:

• A. Left sided heart failure.
• B. Systemic hypertension.
• C. Pericardial effusion.
• D. Right sided heart failure.

Answer: (A)

Pulmonary edema happens when fluid accumulates in the lungs due to high pressure in the pulmonary capillaries. The usual trigger is left-sided heart failure: when the left ventricle can’t pump blood effectively into the systemic circulation, blood backs up into the left atrium and then into the pulmonary veins. This backpressure raises the hydrostatic pressure in the pulmonary capillaries, driving fluid into the lung interstitium and alveoli. The result is shortness of breath, crackles on exam, and often pink frothy sputum. Systemic hypertension may contribute to heart disease but doesn’t directly cause pulmonary edema unless it progresses to left ventricular failure. Pericardial effusion can impair heart filling and output but isn’t the classic cause of pulmonary edema. Right-sided heart failure backs up blood to the body, leading to peripheral edema rather than fluid accumulation in the lungs.
