A 62-year-old man comes to the physician because of episodic chest pain that manifests as a sensation of precordial tightness, occurs after physical exertion, and is relieved promptly by rest. The patient has noted that the amount of activity sufficient to trigger the pain is relatively constant, such as climbing three flights of stairs or walking uphill for a few minutes. An ECG recorded at rest, however, fails to show any abnormalities. Which of the following is the most appropriate next step in diagnosis?
(A) Ambulatory ECG monitoring
(B) Echocardiography
(C) Exercise ECG
(D) Myocardial perfusion scintigraphy
(E) Coronary arteriography
