  Purpose

The main objective of this study will be to compare the diagnostic performances of 82Rubidium-PET associated to pharmacologic stress (Persantine) to 99mTc-Sestamibi-SPECT with CZT cameras associated to a stress test (exercise, pharmacological, mixed) for detection of myocardial ischemia in a population of overweighed patients on one hand, and women on the other hand, in a population with an intermediate prevalence of coronary artery disease (≥ 3 cardiovascular risk factors in asymptomatic patients or prevalence of CAD ≥ 30 % using the DIAMOND-FORRESTER score in symptomatic patients).

Primary Outcome Measures:
  • Myocardial ischemia [ Time Frame: 1 year ] [ Designated as safety issue: No ]

    Patients will be classified as positive in case of:

    • Coronary stenosis ≥ 50 % on coronary angiography and fractional flow reserve < 0.8, or, in absence of FFR, a critical coronary stenosis.
    • In absence of coronary angiography, presence of cardiovascular event during the following year.


Secondary Outcome Measures:
  • Size and intensity of myocardial ischemia [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    1. Size and intensity of myocardial ischemia quantified using the sum difference score,
    2. Left ventricular function at stress and at rest
    3. Values of FFR measured invasively and noninvasively
    4. Effective dose caused by radiation exposure
    5. Costs of the two diagnostic strategies


Estimated Enrollment: 310
