It is well known that taking a good history and physical, getting a non-ischemic EKG, and serial cardiac biomarkers, results in a risk of death/AMI of <5% in 30 days. Patients, in whom you still suspect have CAD, should undergo provocative testing within the next 72 hours based on the AHA/ACC guidelines. Their guidelines deem provocative testing as including:
- Exercise treadmill stress test,
- Myocardial perfusion scan,
- Stress echocardiography, and/or
- Coronary CT angiography (CCTA).
