Key result
Mild-to-moderate essential hypertension is linked to lower capillary erythrocyte velocity, inversely tracking 24-hour ambulatory BP.
Why the study?
The relationship between capillary morphology, erythrocyte velocity, and blood pressure in mild-to-moderate essential arterial hypertension was not well characterized.
Does 24-h ambulatory blood pressure correlate with capillary erythrocyte velocity and morphology in patients with mild-to-moderate essential hypertension?
Comparison
Patients vs matched controls
Design
Cross-sectional study with 24-h ambulatory blood pressure and capillaroscopic examination

Ambulatory BP tracking may better capture microcirculatory changes than office readings in mild hypertension; leaves open whether capillaroscopy refines risk assessment.

Does 24-h ambulatory blood pressure correlate with capillary erythrocyte velocity and morphology in patients with mild-to-moderate essential hypertension?
In patients with mild-to-moderate essential hypertension, capillary erythrocyte velocity is reduced compared to controls and inversely correlates with 24-h ambulatory blood pressure.
Duprez et al. (1992) conducted a cross-sectional in Mild-to-moderate essential arterial hypertension (n=15). Mild-to-moderate essential arterial hypertension vs. Matched controls was evaluated on Correlation of capillary morphology and erythrocyte velocity to blood pressure. Mild-to-moderate essential hypertension was associated with significantly lower capillary erythrocyte velocity compared to matched controls, and inversely correlated with 24-h ambulatory BP.
