Which factors aggravate symptoms in acute pericarditis?

• A. Worsened when lying flat and with inspiration
• B. Improved when upright and with coughing
• C. Unchanged by position
• D. Relieved by ambulation

Answer: (A)

Acute pericarditis classically causes sharp, pleuritic chest pain that is strongly influenced by position and breathing. When you lie flat, venous return to the heart increases and the inflamed pericardium is stretched more, plus the rubbing between inflamed layers is intensified, all of which worsens the pain. Deep inspiration also worsens the pain because it expands the chest and increases motion and friction at the inflamed surfaces. In contrast, sitting upright and leaning forward relieves the discomfort by reducing the distance between the pericardium and chest wall and decreasing pericardial pressure, so the pain diminishes. Coughing, ambulation, or being unchanged by position do not typically provide relief and can even aggravate pleuritic pain, so they’re not the characteristic pattern.
