The effects of ACE inhibition with perindopril on the atherosclerosis-induced impairment of arterial flow were investigated via histopathologic studies, hemodynamics, and vascular rheology of hindlimb arteries in 7 adult Pitman-Moore mini-pigs (7 months of age) fed for 4 months with an atherogenic diet and perindopril (at the daily oral dose of 4 mg, which induced a continuous 70% inhibition of serum ACE activity), versus 7 atherogenic and 7 control animals. Major fibroproliferative fatty lesions with medial intimalization were observed in the abdominal aorta. Atherosclerosis impaired the function of both capacitance and resistance hindlimb arteries. In atherogenic mini-pigs, blood pressure (BP) increased significantly due to increased hindlimb peripheral resistance (HPR) and aortic input impedance, although aortic blood flow was not affected. Altered aortic wall rheology revealed that the stiffness of the aorta was markedly increased due to increased wall tension and reduced viscoelasticity, the viscous component being reduced in the arterial wall. Perindopril significantly opposed these alterations by reducing BP, HPR and input impedance and by returning parietal stiffness to control values by increasing aortic compliance. Angiotensin converting enzyme (ACE) inhibition significantly prevented the development of atherosclerosis in the abdominal aorta by decreasing the cross-sectional area of lesions and the presence of lipid-laden cells, as well as by preventing alteration and fragmentation of elastic laminae. In conclusion, ACE inhibition with perindopril showed a significant preventive action on atherosclerosis-induced deleterious effects on vascular wall function and structure in mini-pig arteries.
