The patient is a 46-year-old male. He was admitted to hospital after one-month paroxysmal chest pain. With each attack, sublingualnitroglycerincould relieve chest pain. We consider the disease as coronary heart disease and angina. The most commonly used method of examinationis A: Coronary CTA B: Radionuclide inspection C: DCG D: UCG
