We evaluated the therapeutic effectiveness of a new, orally active epoxyeicosatrienoic acid analog (EET-A) in rats with angiotensin II (ANG II)-dependent malignant hypertension.
Such increased urinary angiotensinogen excretion may contribute to augmented intrarenal ANG II levels and, thereby, to the increased blood pressure in Cyp1a1-Ren2 transgenic rats with inducible ANG II-dependent malignant hypertension.
Forty-two patients with malignant hypertension (mean age 55 years), 42 patients with non-malignant hypertension (mean age 57 years) and 85 normotensive control subjects (mean age 42 years) were investigated with respect to ACE I/D and AGT M/T genotypes.
The Tsukuba hypertensive mouse (transgenic mouse carrying human genes for both renin and angiotensinogen) as a model of human malignant hypertension: development of lesions and morphometric analysis.
Tissue angiotensin converting enzyme inhibition at a non-hypotensive dose almost completely prevented mortality from malignant hypertension and significantly reduced tissue injury in this model, implicating angiotensin II rather than high blood pressure as the principal 'vasculotoxic' agent in malignant hypertension.
