Effects of simvastatin on pulmonary C-fiber sensitivity in rats with monocrotaline-induced pulmonary hypertension

Simvastatin treatment in MCT-PH rats not only attenuated pulmonary hypertension, but also desensitized PCF hypersensitivity and decreased the production of ROS. These cholesterol-independent effects were mainly through the HO-1 pathway and may all contribute to the therapeutic effects of PH treatment.
