Overview

Myocardial viability studies can determine whether hypocontractile myocardium is viable but just hibernating, and could therefore benefit from revascularization.

Myocardial Viability Studies

Common imaging modalities to assess myocardial viability include:

• Dobutamine echocardiography
• Nuclear tests (SPECT or PET)
• Cardiac MRI

Class IIb

"Non-invasive stress imaging (CMR, stress echocardiography, SPECT, PET) may be considered for the assessment of myocardial ischemia and viability in patients with CAD who are considered suitable for coronary revascularization. (Level of Evidence: B) "

". Exercise testing may be considered to detect reversible myocardial ischemia and investigate the cause of dyspnea(Level of Evidence: C) "

The above table adopted from 2021 ESC Guideline
