Radial measurements may underestimate nitroglycerin effects on central systolic pressure; leaves open whether central monitoring improves vasodilator titration.
Does upper limb blood pressure measurement underestimate the vasodilator effects of sublingual nitroglycerin on ascending aortic systolic pressure?
Upper limb blood pressure measurement underestimates the central aortic systolic pressure reduction caused by nitroglycerin, though the late systolic shoulder in the radial artery reflects this central reduction.
Takazawa et al. (1995) studied this question.
