SPECT myocardial perfusion imaging is better at identifying perfusion defects and predicting cardiovascular death or morbidity compared with electrocardiograms, according to a study published in the European Heart Journal: Cardiovascular Imaging. Fifty percent of 650 patients with suspected or known heart disease who had normal findings from exercise ECGs showed abnormal results on SPECT MPI, the study said. Abnormal SPECT findings can be a strong predictor of death or major adverse cardiac events, researchers said.
