New CT scan Simulates Blood Flow to Assess Angina Risk

CT angiography-derived fractional flow reserve (CT-FFR) is a noninvasive test that effectively identifies low-risk stable angina patients, irrespective of high coronary artery calcium scores, as per a recent Radiology study. Results show a 2.1% three-year adverse outcome rate in patients with normal CT-FFR, regardless of calcium scores, versus a 9% rate in those with abnormal CT-FFR, even with low calcium scores. This highlights CT-FFR’s utility in assessing stable angina patient risk and potentially reducing unnecessary invasive procedures.
