Contractile properties of papillary muscle from young cardiomyopathic hamsters: effects of isoprenaline.

abstract：AIMS:Neointimal hyperplasia is a common feature of fibro-proliferative vascular disease and characterizes initial stages of atherosclerosis. Neointimal lesions mainly comprise smooth muscle-like cells. The presence of these lesions is related to local differences in shear stress. Neointimal cells may arise through migr...
