Validates radionuclide plethysmography for acute venous tone assessment; leaves open whether nitroglycerin venodilation alters clinical outcomes versus nifedipine.
Do sublingual nifedipine and nitroglycerin change forearm venous volume and tone in patients?
Radionuclide plethysmography is a valid method for assessing acute changes in venous tone, demonstrating that nitroglycerin induces significant venodilation while nifedipine does not.
Manyari et al. (1988) studied this question.
