Sequential renal hemodynamics in experimental benign and malignant hypertension.

Journal Article (Journal Article)

To examine the sequential renal hemodynamic changes in experimental renovascular hypertension, the uninephrectomized dog was studied immediately after renal artery constriction, throughout chronic benign hypertension, and during malignant hypertension. Intrarenal resistance fell immediately after renal artery constriction, but rose above control within hours. Intrarenal infusion of teprotide resulted in vasodilatation during the first 3 days but failed to do so during the chronic phase of benign hypertension. During the transition from benign to malignant hypertension, angiotensin II-dependent renal vasoconstriction developed associated with natriuresis, plasma volume contraction and a vicious cycle of hyperreninemia and severe vascular damage.
