Which symptom is most commonly associated with pericardial effusion?

• A. Chest pain radiating to left arm
• B. Shortness of breath
• C. Fever
• D. Syncope

Answer: (D)

Shortness of breath is the symptom most commonly associated with pericardial effusion. When fluid builds up in the pericardial space, it can impair the heart’s ability to fill properly, especially during activity, leading to reduced cardiac output and breathlessness. The amount of fluid, how quickly it accumulates, and the patient’s baseline function all influence how breathlessness presents. Chest pain that radiates to the left arm is more typical of coronary ischemia, while fever points toward infection or pericarditis rather than a simple effusion. Syncope can occur, but it usually signals a more advanced problem—tamponade—where the pressure from the fluid severely limits heart filling, causing a transient drop in cerebral perfusion. In tamponade you’d also expect signs like hypotension, elevated neck venous pressure, and muffled heart sounds.
