WEDNESDAY, April 24, 2024 (HealthDay News) — Computed tomography fractional flow reserve (CT-FFR) improves assessment of vessel blockages and reduces the number of stenosis patients referred for invasive revascularization procedures, according to a study published online April 4 in Radiology: Cardiothoracic Imaging<\/em>.<\/p>\n Mangun K. Randhawa, M.D., from Massachusetts General Hospital and Harvard Medical School in Boston, and colleagues assessed three-month clinical outcomes among 284 patients with significant stenosis who underwent CT-FFR analysis of dual-source CT scans without heart rate control.<\/p>\n The researchers found that 56.3 percent had CT-FFR >0.80 (a negative result), 30.9 percent had a clearly positive result (\u00e2\u0089\u00a40.75), and 12.6 percent had a borderline result between 0.76 and 0.80. Among patients with significant stenosis at coronary CT angiography, patients who underwent CT-FFR analysis had lower rates of invasive coronary angiography (74.5 versus 25.5 percent) and percutaneous coronary intervention (78.9 versus 21.1 percent).<\/p>\n “In patients with moderate narrowing or blockage of the arteries, there can be ambiguity about who would benefit from invasive testing and revascularization procedures,” Randhawa said in a statement. “CT-FFR helps us identify and select those patients who are most likely to benefit.”<\/p>\n Abstract\/Full Text (subscription or payment may be required)<\/a><\/p>\n <\/i><\/p>\n
