Abstract: An asymptomatic 40-year-old man with no conventional risk factors for coronary artery disease had a positive treadmill stress test based on ECG criteria. Coronary CT angiography showed a small plaque in the left anterior descending artery and dobutamine-atropine stress echocardiography was negative for myocardial ischemia but showed a significant outflow gradient (100 mmHg) during pharmacological stress.
