Key result
In rats with modest two kidney Goldblatt hypertension, mean hydrostatic pressure within glomerular capillaries was elevated compared to normotensive controls (55 vs 48 mm Hg, p<0.05).

Elevated glomerular capillary pressure in this rat model supports early hemodynamic changes in experimental hypertension; hypothesis-generating and requires validation before clinical translation.
Does modest two-kidney Goldblatt hypertension alter glomerular hemodynamics in rats?
Absolute Event Rate: 55% vs 48%
p-value: p=<0.05
Glomerular hemodynamics are altered early in modest Goldblatt hypertension in rats, with increased capillary pressure offset by decreased permeability, maintaining normal filtration rates.
Steiner et al. (1982) studied Goldblatt hypertension. Modest two kidney Goldblatt hypertension vs. Normotensive controls was evaluated on Mean hydrostatic pressure within glomerular capillaries (p=<0.05). In rats with modest two kidney Goldblatt hypertension, mean hydrostatic pressure within glomerular capillaries was elevated compared to normotensive controls (55 vs 48 mm Hg, p<0.05).
