Question

chest pain that is exacerbated by exercise and is relieved by rest is most likely due to
pericarditis
diaphragmatic irritation
coronary ischemia
pleurisy

Explanation:

Coronary ischemia often causes chest - pain (angina) that worsens with exercise as the heart's demand for oxygen increases and is relieved by rest when the heart's oxygen demand decreases. Pericarditis pain is often positional and worsens with deep breathing or lying down. Diaphragmatic irritation may cause pain related to respiratory or abdominal movements. Pleurisy pain is associated with breathing and is due to inflammation of the pleura.

Answer:

coronary ischemia
