MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Approximately 10 million patients present to emergency rooms in the US annually for evaluation of acute chest pain.
The goal of that evaluation is to rule out the diagnosis of an acute heart attack. Imaging with coronary CT angiography and stress testing are not part of the diagnostic algorithm for acute heart attack. Nevertheless many chest pain patients undergo some form of noninvasive cardiac testing in the ER. We found that CCTA or stress testing adding nothing to the care of chest pain patients beyond what is achieved by a history, physical examination, ECG and troponin test.
