FLNA and Hypertension: As these time‐varying effects have been neglected by Poiseuille‐derived methods, an interesting point arises when considering that factors which influence FMD variability (e.g., hypertension, age, gender, and baseline diameter (Thijssen et al., 2019)) are known to modulate the (1) amplitude and contour of the systemic pressure waveform and (2) subsequent arterial velocity waveforms.
