Does equilibrium radionuclide angiocardiography detect left ventricular dysfunction during exercise as frequently as heart catheterization in patients with effort angina?
Equilibrium radionuclide angiocardiography is as effective as invasive heart catheterization in detecting exercise-induced left ventricular dysfunction in patients with effort angina.
Dahlström et al. (1982) conducted an observational in Effort angina (n=10). Radionuclide angiocardiography vs. Heart catheterization was evaluated on Detection of left ventricular dysfunction. Radionuclide angiocardiography revealed left ventricular dysfunction during exercise as frequently as heart catheterization in patients with effort angina.
