Ang II raises BP in rats with reduced renal mass; hypothesis-generating for mechanisms in early CKD but should not inform clinical practice.
Does chronic Ang II infusion increase blood pressure in partially nephrectomized rats?
p-value: p=<0.05
Elevated circulating Ang II causes sustained hypertension in rats with reduced functional renal mass, highlighting its role in blood pressure regulation during incipient renal impairment.
Yasujima et al. (1993) studied Reduced functional renal mass (partially nephrectomized). Angiotensin II vs. Vehicle alone was evaluated on Systolic blood pressure (p=<0.05). Chronic infusion of Angiotensin II at a subpressor dose caused a significant increase in systolic blood pressure in partially nephrectomized rats compared to vehicle controls.
