A 61-year-old male patient, complaining of progressive exertional chest tightness, relieved by rest, for the past 11 years, was referred to us with suspected coronary artery disease (CAD). Standard twelve lead electrocardiography (ECG) revealed ST-T segment changes on leads V2-V6 and T wave inversion. A coronary CT angiography (CTA) combined with ATP-stress myocardial CT perfusion was requested to investigate the coronary artery status and myocardial blood flow.
