Randomized Controlled Trial Multicenter Study Comparative StudyCoronary CT angiography versus myocardial perfusion imaging for near-term quality of life, cost and radiation exposure: a prospective multicenter randomized pilot trial.
Clinical outcomes and resource utilization after coronary computed tomography angiography (CTA) versus myocardial perfusion single-photon emission CT (MPS) in patients with stable angina and suspected coronary artery disease (CAD) has not been examined. ⋯ In a pilot randomized controlled trial, patients with stable CAD undergoing coronary CTA and MPS experience comparable improvements in near-term angina-related quality of life. Compared with MPS, coronary CTA evaluation is associated with more aggressive medical therapy, increased coronary revascularization, lower total costs, and lower effective radiation dose.
