Effect of alpha-tocopherol on restenosis after angioplasty in a model of experimental atherosclerosis.

The ability of alpha-tocopherol to reduce restenosis after angioplasty was tested in a rabbit model in which angioplasty was performed on established atherosclerotic lesions. Lesions induced by 4 wk of cholesterol feeding after focal desiccation of femoral arteries were balloon dilated. 3 wk after angioplasty, angiographically determined minimum luminal diameters were less in the untreated group (0.80 +/- 0.51 mm) than in the group treated with oral alpha-tocopherol beginning 19 d before angioplasty (1.38 +/- 0.29 mm; P < 0.01). The cross-sectional area of the intima-media was greater in the untreated group (1.18 +/- 0.48 mm2) than in the alpha-tocopherol group (0.62 +/- 0.25 mm2, P < 0.0001). These differences were not due to vasoconstriction or altered plasma cholesterol. Alpha-tocopherol thus reduced restenosis after angioplasty in this model. In rabbit vascular smooth muscle cells, oxidized low density lipoprotein stimulated DNA synthesis. Alpha-tocopherol treatment inhibited DNA synthesis stimulated by oxidized low density lipoprotein, but not by serum. The findings are consistent with the hypothesis that oxidized lipids can stimulate hyperplasia and that antioxidants may limit hyperplasia by inhibiting either the oxidation or the proliferative effects of oxidants on cells.[1]
