Key result
99mTc MIBI SPECT shows comparable sensitivity to DSE for detecting viable myocardium.
Why the study?

May support MIBI SPECT consideration with poor windows; leaves open randomized validation in low-LVEF CAD.
Observational (n=50)
Does 99mTc MIBI myocardial perfusion SPECT match Dobutamine Stress Echocardiography in detecting viable myocardium in patients with CAD and poor LV function?
Absolute Event Rate: 86.5% vs 87.6%
p-value: p=0.875
99mTc MIBI SPECT has comparable diagnostic accuracy to Dobutamine Stress Echocardiography for detecting myocardial viability in patients with CAD and poor LV function, offering a good alternative for patients with poor acoustic windows.
Jha et al. (2023) conducted an observational in Coronary Artery Disease (n=50). 99mTc MIBI myocardial perfusion SPECT vs. Dobutamine Stress Echocardiography (DSE) was evaluated on Detection of viable myocardium segments (sensitivity) (p=0.875). 99mTc MIBI SPECT demonstrated comparable sensitivity to Dobutamine Stress Echocardiography for detecting viable myocardium (86.5% vs 87.6%; p=0.875).
