Prognostic Value of SPECT-imaging Myocardial Perfusion Heterogeneity (EVAPERF)

Read time: 1 mins
Last updated:4th Aug 2014

Endothelial dysfunction has been demonstrated to be an early marker of coronary artery disease (CAD). On the other hand, myocardial perfusion single photon emission computed tomography (MP-SPECT) is a widely used technique for evaluation of patients with suspected or known CAD.

Preliminary data suggest that myocardial perfusion heterogeneity (a potential surrogate marker of endothelial dysfunction) can be assessed on conventional MP-SPECT, but its additive and independent prognostic value over the presence of myocardial ischemia remain unknown.

Accordingly, the purpose of this study is to evaluate the prognostic value of myocardial perfusion heterogeneity assessed by a new automatized image processing method applied to routine MP-SPECT.

The main hypothesis is that the presence of myocardial perfusion heterogeneity is predictive of 2-year cardiovascular events in patients referred to the Nuclear Cardiology Department for routine evaluation of known or suspected CAD.
