Myocardial perfusion imaging by ¹⁵O-H₂O positron emission tomography predicts clinical revascularization procedures in symptomatic patients with previous coronary artery bypass graft.

ABSTRACT:

Aims

We wanted to assess if ¹⁵O-H₂O myocardial perfusion imaging (MPI) in a clinical setting can predict referral to coronary artery catheterization [coronary angiography (CAG)], execution of percutaneous coronary intervention (PCI), and post-PCI angina relief for patients with angina and previous coronary artery bypass graft (CABG).

Methods and results

We analysed 172 symptomatic CABG patients referred for ¹⁵O-H₂O positron emission tomography (PET) MPI at Aarhus University Hospital Department of Nuclear Medicine & PET Centre, of which five did not complete the scan. In total, 145 (87%) enrolled patients had an abnormal MPI. Of these, 86/145 (59%) underwent CAG within 3 months; however, no PET parameters predicted referral to CAG.
