Randomized controlled trials of imaging strategies for chest pain

Our recently completed multicenter randomized controlled trials have established the efficacy of a coronary CT angiography-based diagnostic strategy for chest pain. The ROMICAT II trial (n=1,000) found that a CT for acute chest pain resulted in improved efficiency of clinical decision making. The PROMISE trial (n=10,000) found that a CT diagnostic strategy resulted in similar outcomes to functional testing for stable chest pain. Our current efforts focus on whether coronary plaque morphology can predict which patients are at greatest risk. Please see the coronary CT image (on the right) demonstrating severe stenosis of the left anterior descending coronary artery (arrow).
