Why the study?
82Rb-PET is increasingly used for stable CAD, but the prognostic value of 82Rb-PET-derived parameters in patients with symptoms suggestive of CAD without perfusion defects needed evaluation.
Do 82Rb-PET-derived parameters predict adverse cardiovascular outcomes in patients with suspected stable CAD and no perfusion defects?

2175 patients suspected of stable CAD undergoing 82Rb-PET with no regional perfusion defects
Comparison

May support risk stratification in suspected stable CAD without perfusion defects; hypothesis-generating, needs prospective validation.
Do 82Rb-PET-derived parameters predict adverse cardiovascular outcomes in patients with suspected stable CAD and no perfusion defects?
82Rb-PET-derived parameters including myocardial blood flow reserve, LVEF, and LVEF-reserve provide significant prognostic information in patients with suspected stable CAD but no perfusion defects.
