Use of computed tomography coronary angiography (CTA), which provides 3-D images of the heart, coupled with standard care allows doctors to more accurately diagnose coronary artery disease in patients presenting with chest pain. This has led to more appropriate follow-up testing and treatments, according to research presented at the American College of Cardiology (ACC) 2015 Annual Scientific Session. Data also showed a trend toward a lower incidence of heart attacks among the group receiving CT scans, compared to usual care.
