Key result
Sodium-resistant borderline hypertensive males had significantly fewer perfused capillaries during hyperaemia compared to both sodium-sensitive and normotensive control subjects.

Does nailfold capillary density differ between sodium-sensitive and sodium-resistant borderline hypertensive males?
Sodium-resistant borderline hypertension may be characterized by a structural reduction in nailfold capillarity during hyperaemia compared to sodium-sensitive hypertension and normotension.
Draaijer et al. (1993) conducted a cross-sectional in Borderline hypertension (n=55). Sodium-resistant borderline hypertension vs. Sodium-sensitive borderline hypertension and normotension was evaluated on Nailfold capillary density at rest and after 4 min circulatory arrest (hyperaemia). Sodium-resistant borderline hypertensive males had significantly fewer perfused capillaries during hyperaemia compared to both sodium-sensitive and normotensive control subjects.
