Does surgical abdominal aorta stenosis induce aorta remodelling and intimal lesions in male young rats?
Increased circumferential wall tension due to hypertension plays a pivotal role in aortic remodeling through biomechanical effects on oxidative stress and increased TGF-beta expression.
Prado et al. (2006) conducted an RCT in Hypertension and aorta remodelling. Surgical abdominal aorta stenosis vs. Sham operation was evaluated on Aorta remodelling (intimal lesions, medial thickening, and protein expression). Surgical abdominal aorta stenosis in male rats induced increased circumferential wall tension, leading to neointimal plaques, medial thickening, and increased TGF-beta expression.
