Key result
In 102 patients, stress RV/LV uptake ratios on exercise SPECT using CZT cameras correlated positively with left main or multivessel disease and tricuspid regurgitation maximum pressure gradient.
Why the study?
Does the RV/LV uptake ratio on exercise thallium-201 SPECT using CZT cameras correlate with severe CAD and echocardiographic parameters in patients with suspected CAD?

Does the RV/LV uptake ratio on exercise thallium-201 SPECT using CZT cameras correlate with severe CAD and echocardiographic parameters in patients with suspected CAD?
RV/LV uptake ratios on exercise CZT SPECT can help detect severe CAD and indicate pulmonary hypertension and LV diastolic dysfunction.
Ko et al. (2016) conducted an observational in Suspected coronary artery disease (n=102). RV/LV uptake ratios on treadmill thallium-201 SPECT using CZT cameras was evaluated on Presence of CAD (≥50% stenosis in the left main or ≥70% in the main branches) and echocardiographic parameters. In 102 patients, stress RV/LV uptake ratios on exercise SPECT using CZT cameras correlated positively with left main or multivessel disease and tricuspid regurgitation maximum pressure gradient.
