The hypertensive state was associated with significantly elevated digital mean arterial pressures, vascular resistances, and venous pressure compared to normal subjects, with similar digital blood flow.

How do digital hemodynamics differ between normotensive and hypertensive subjects?
Hypertension is associated with elevated digital mean arterial pressures and vascular resistance, but digital blood flow remains similar to normotensive individuals.
Rheoplethysmographic studies were conducted to evaluate the digital hemodynamics of the hypertensive state. It is concluded that digital blood flow is similar in normal and hypertensive subjects; digital mean arterial pressures and calculated vascular resistances were significantly elevated in the hypertensive as compared to the normal subject; there is a small but definite increase in digital venous pressure in the hypertensive state; and the digital vasculature and in particular the arteriovenous shunts are otherwise similar in both the normal and the hypertensive subject.
Caliva et al. (Sun,) conducted a observational in Hypertension. Hypertensive state vs. Normotensive state was evaluated on Digital hemodynamics. The hypertensive state was associated with significantly elevated digital mean arterial pressures, vascular resistances, and venous pressure compared to normal subjects, with similar digital blood flow.
