Implication
May refine risk stratification in suspected CAD; hypothesis-generating and requires prospective validation before practice change.
Structured PICO
Does multislice computed tomography (MSCT) provide incremental prognostic value over myocardial perfusion imaging (MPI) in patients with suspected coronary artery disease?
P
Population
541 patients with suspected coronary artery disease referred for further cardiac evaluation, mean age 59 +/- 11 years, 59% male.
I
Intervention
Multislice computed tomography (MSCT) coronary angiography in addition to myocardial perfusion imaging (MPI)
C
Comparator
Single-photon emission computed tomography myocardial perfusion imaging (MPI) alone
O
Outcome
Composite of all-cause death, nonfatal infarction, and unstable angina requiring revascularizationcomposite
MSCT provides incremental prognostic value over MPI in patients with suspected CAD, and their combined anatomical and functional assessment improves risk stratification.
