A patient with atherosclerotic heart disease experiences chest pain during exertion because: A. the ragged edge of a tear in the coronary artery lumen causes local blood clotting and arterial narrowing. B. the lumen of the coronary artery is narrowed and cannot accommodate increased blood flow. C. tissues of the myocardium undergo necrosis secondary to a prolonged absence of oxygen. D. the coronary arteries suddenly spasm and cause a marked reduction in myocardial blood flow.

B. the lumen of the coronary artery is narrowed and cannot accommodate increased blood flow.
