A 75-year-old male patient, with high blood pressure and elevated cholesterol levels, was admitted due to a recent onset of atypical chest discomfort. The physical examination was unremarkable. Biometric parameters, such as weight (58 kg), height (169 cm), heart rate (53 bpm), blood pressure (130/80 mmHg), as well as ECG and echocardiogram were normal at admission. A maximal treadmill stress test (Bruce Protocol) disclosed moderate exercise tolerance (7’30’’) with no angina but minor ST-T changes on the left precordial leads. A coronary CT angiography (cCTA) was requested for further evaluation.
