The prognostic value of single photon emission computed tomography (SPECT) myocardial perfusion imaging is independent of left ventricular size.

ABSTRACT: Many variables have been shown to impact accuracy and prognostic power of myocardial perfusion imaging (MPI); however, effects of left ventricular size have not been extensively studied. In particular, perfusion defects in smaller hearts could be overlooked due to partial volume averaging, potentially reducing the prognostic power of MPI. We determined stress total perfusion deficit (TPD) and rest end diastolic volume (REDV) from single photon emission computed tomography (SPECT) MPI in consecutive patients without pathologically dilated left ventricles. Area under the curve (AUC) and Cox regression analysis were used to assess prediction of subsequent major adverse cardiac events [MACE-death, hospitalized acute myocardial infarction (AMI), hospitalized unstable angina, late revascularizat
