They compared qualitative CMR and quantitative CMR to an established prognostic formula (combining age, sex and late gadolinium enhancement) based on their ability to predict the two-year incidence of MACE.

The quantitative measure of ischemia was defined as myocardial perfusion reserve of less than 1.5 based on a Fermi function deconvolution—the same threshold used in positron emission tomography (PET).

The AUC improved to 0.84 with visual CMR and 0.85 with quantitative CMR when using the ischemic burden thresholds.

The findings of this study have important implications for facilitating more widespread adoption of stress perfusion CMR by less experienced readers and allowing the prognostic value of perfusion quantification to be realized.”

In both cases, the thresholds were found to apply to CMR and improved the predictive value of those methods versus identifying ischemic burden as a continuous variable.

Arai, MD, said stress perfusion CMR seems well-positioned to take “a larger role in the management of stable coronary disease.” It is reimbursed by Medicare similarly to the more widely used single-photon emission computed tomography (SPECT), he noted, and is piling up evidence showing its usefulness.
