Coronary Computed Tomography Versus Invasive Angiography for Non-ST Elevation Acute Coronary Syndrome

Coronary computed tomography angiography (CCTA) is a widely accepted initial diagnostic test for individuals suspected of having chronic coronary syndromes. However, there is limited evidence supporting its use in the acute setting. So far, no large-scale randomized trial has examined the performance of CCTA as an alternative to invasive coronary angiography (ICA) in individuals with non-ST-segment elevation myocardial infarction (NSTEACS).

If CCTA were to replace ICA as a routine procedure for individuals with NSTEACS, it could reduce the risk of complications related to ICA, improve patient comfort, expedite decision-making, and reduce healthcare expenses and interhospital transfers.
