Chest Pain: Coronary CT Angiography in the ED
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).


Every year there are 6 million visits to the Emergency Department (ED) for chest pain, and approximately 2 million hospital admissions each year.
There was recently a great study published in the American Journal of Cardiology (2012) by Sharifi et al
Pulmonary embolism (PE) can be a deadly disease and one of the most challenging diagnosis to make in a pregnant patient. Patients may present with signs and symptoms that might also be present in a normal uncomplicated pregnancy. Even in nonpregnant patients, the diagnosis of venous thromboembolism (VTE) such as PE can be quite challenging.
