Endothelin-1 promotes vascular structural remodeling during the progression of heart failure prevention of vascular remodeling using a specific endothelin-converting enzyme inhibitor.

Abstract To evaluate the effects of endothelin (ET)-converting enzyme (ECE) inhibitor on vascular remodeling in dogs with congestive heart failure (CHF), we chronically administered an ECE inhibitor, FR901533 (FR, iv. 0.3mg/kg/hr, n=6), to dogs with CHF induced by rapid ventricular pacing. Vehicle CHF dogs were given saline (n=7). In the vehicle CHF group after 3 weeks of pacing, the ET system was activated in the plasma and vasculature (3 and 5 times higher than normal, respectively). Inward remodeling occurred in the femoral artery; medial thickness (MT, 225±5 vs 193±4 μm, P
