Key result
Patients with essential hypertension had a greater brachial to digital systolic pressure gradient than normotensive controls during both regulated heating and cooling.
Why the study?
Does the brachial to digital blood pressure gradient differ between normal subjects and patients with essential hypertension under regulated vasoconstriction and vasodilatation?
Population
16 subjects total: 10 patients with essential hypertension and 6 subjects with normal blood pressure.
Comparison
Exposure to regulated peripheral… vs Normotensive control subjects.
Design
Cross-sectional

Hypertension-associated brachial-digital gradient differences warrant no practice change; leaves open diagnostic or mechanistic roles.

Does the brachial to digital blood pressure gradient differ between normal subjects and patients with essential hypertension under regulated vasoconstriction and vasodilatation?
Hypertensive patients exhibit a greater brachial to digital systolic pressure gradient compared to normotensive subjects regardless of peripheral vasomotor state.
Gaskell et al. (1958) conducted an observational in Essential hypertension (n=16). Essential hypertension vs. Normal blood pressure was evaluated on Brachial to digital systolic and diastolic pressure gradients. Patients with essential hypertension had a greater brachial to digital systolic pressure gradient than normotensive controls during both regulated heating and cooling.
