Values are %.

MPS = myocardial perfusion single-photon emission computed tomography; SDS = summed difference score; SRS = summed rest score; SSS = summed stress score.

  • In patients with abnormal baseline MPS, results are reported separately for patients who underwent medical or medical plus revascularization therapy.
