Outcomes of Anatomical versus Functional Testing for Coronary Artery Disease
Why the study?
Does a strategy of initial CTA improve clinical outcomes compared to functional testing in symptomatic patients with suspected CAD who require noninvasive testing?
Population
symptomatic patients with suspected CAD who required noninvasive testing
Comparison
strategy of initial CTA (anatomical testing) vs functional testing
Design
RCT

Implication
Initial CTA yields no outcome benefit over functional testing in suspected CAD; challenges assumptions favoring anatomical-first strategies.
Structured PICO

P
Population
symptomatic patients with suspected CAD who required noninvasive testing
I
Intervention

C
Comparator
functional testing
O
Outcome
clinical outcomes
In symptomatic patients with suspected CAD, an initial strategy of anatomical testing with CTA does not improve clinical outcomes compared to functional testing.
