Alluvial diagram of diagnostic testing in PROMISE and SCOT-HEART. (A) Among 10 003 participants randomized to anatomical vs. functional testing in the PROMISE trial, a total of 4834 vs. 4734 individuals underwent an anatomical vs. functional test as their initial investigation (and were included in this study), with 402 patients receiving no testing and the remaining 29 undergoing invasive coronary angiography as the initial diagnostic test. (B) Among 4146 chest pain patients in SCOT-HEART who were randomized to standard care vs. standard care plus computed tomography coronary angiography, a total of 301 patients underwent computed tomography coronary angiography imaging without baseline stress electrocardiography vs. 1834 patients who underwent stress/functional testing as their initial investigation without the addition computed tomography coronary angiography. CTCA, computed tomography coronary angiography; ECG, electrocardiography; PROMISE, PROspective Multicenter Imaging Study for Evaluation of Chest Pain; SCOT-HEART, Scottish COmputed Tomography of the HEART Trial.
