Key result
Cardiac CT for stable chest pain (N=500) improved angina symptoms and resulted in fewer investigations and re-hospitalizations at 1 year compared with exercise stress electrocardiography.
Why the study?
Does cardiac CT improve angina symptoms and reduce clinical events compared to exercise stress electrocardiography in patients with troponin-negative stable chest pain?
RCT (n=500)
Does cardiac CT improve angina symptoms and reduce clinical events compared to exercise stress electrocardiography in patients with troponin-negative stable chest pain?
Using cardiac CT instead of exercise stress testing as the initial investigation for stable chest pain leads to better symptom control, fewer inconclusive results, and fewer downstream hospitalizations.

Supports cardiac CT as initial test for stable chest pain; extends randomized evidence for anatomic over functional strategies.
McKavanagh et al. (2014) conducted an RCT in Stable chest pain (n=500). Cardiac computerized tomography (CT) vs. Exercise stress electrocardiography test (EST) was evaluated on Angina symptoms (Seattle Angina Questionnaires), management strategies, and clinical events. Cardiac CT for stable chest pain (N=500) improved angina symptoms and resulted in fewer investigations and re-hospitalizations at 1 year compared with exercise stress electrocardiography.
