In acute pericarditis, chest pain is typically worsened by which position?

• A. Worsens when lying flat
• B. Improves when lying flat
• C. Worse with standing
• D. Not related to position

Answer: (A)

In acute pericarditis, chest pain is often pleuritic and strongly influenced by posture. The pain typically worsens when you lie flat and is relieved by sitting up and leaning forward. This forward-leaning position changes the orientation of the heart and reduces friction on the inflamed pericardial surfaces, easing the pain. Lying supine increases contact and friction, making the pain worse. This positional pattern—worse lying flat, better when upright and leaning forward—is a classic feature of acute pericarditis.
