Capillary pressure elevation may contribute to vascular resistance in hypertension; hypothesis-generating case-control data requiring prospective confirmation.
Is capillary pressure elevated in patients with essential hypertension compared to normotensive controls?
Direct measurement demonstrates elevated capillary pressure in essential hypertension, suggesting the postcapillary segment plays a role in increased vascular resistance.
Williams et al. (1990) studied this question.
