Myocardial Perfusion Imaging May Enhance CT-based Evaluation of Stable Angina: CRESCENT II
For patients referred for evaluation of stable angina, a tiered protocol progressing from calcium scans to CT angiography to CT myocardial perfusion imaging appears to be a viable alternative to standard functional testing, the CRESCENT-II trial shows, although larger trials are needed to confirm the results. The CT-based approach reduced the rate of invasive coronary angiograms without a class I indication for revascularization compared with functional testing through six months, according to lead author Marisa Lubbers, MD, and colleagues.
