Key result
Exercise radionuclide ventriculography links ischemia to selective regional ejection fraction declines during stress.
Why the study?
Quantitative assessment of exercise-induced regional left ventricular function changes in normal individuals and patients with one vessel coronary artery disease was needed to detect ischemia or scar.
Observational (n=38)

Regional radionuclide EF analysis detects exercise-induced ischemia in LAD/LCx territories; leaves open its incremental value over global measures in modern CAD evaluation.
Pfisterer et al. (1982) conducted an observational in One vessel coronary artery disease (n=38). Exercise equilibrium radionuclide ventriculography vs. Rest / Normal individuals was evaluated on Regional ejection fraction changes during exercise. Exercise equilibrium radionuclide ventriculography showed that regional ejection fraction decreased significantly in ischemic regions but increased or remained unchanged in normal areas.
