CCTAs are not an imaging study for everyone. In fact, standard cardiac angiograms are still the gold standard for diagnosing coronary artery disease. However, for a specific subset of patients it is a very good alternative for ruling out cardiac disease.
Specifically, CCTA is a good choice for the following outpatient groups:
- Unexplained or atypical chest pain in a patient with low to intermediate likelihood of coronary artery disease based on age, gender and other risk factors.
- Typical or atypical chest pain with normal or equivocal stress test and normal or equivocal ECG findings.
To achieve this low exposure to radiation, it is important to make sure the patient’s heart rate is low, and a dose of a medication to slow the heart rate down, such as a beta blocker, is usually recommended prior to the study. This will be done prior to the CT if the heart rate is higher than recommended.
Scheduling a CCTA is done through our Central Scheduling office at (248) 471-8100. The scheduler will advise the patient about the preparation for the test. If you have any further questions regarding a CCTA you should discuss this with a Cardiologist prior to recommending the study to your patients.
