Moderate consumption of red wine is associated with a decreased incidence of cardiovascular diseases in populations with relatively high amount of fat in the diet. However, the mechanisms involved in this protective effect are not completely understood. Here we show that moderate consumption of red wine (equivalent to 2 glasses/day in humans) but not ethanol only, improves blood flow recovery by 32% after hind‐limb ischemia in hypercholesterolemic ApoE‐deficient mice. In ischemic tissues, red wine consumption reduces oxidative stress and increases capillary density by 46%. Endothelial progenitor cells (EPCs) have been shown to have an important role in postnatal neovascu‐larization. We found that the number of EPCs is increased by 60% in ApoE mice exposed to red wine. Moreover, the migratory capacity of EPCs is significantly improved in red wine‐drinking mice. The wine used in our study is a cabernet sauvignon from Langue‐doc‐Roussillon, France, which contains a relatively high concentration (4–6 mg/L) of the polyphenolic antiox‐idant resveratrol. We demonstrate that resveratrol can rescue oxidized low‐density lipoprotein (oxLDL)‐in‐duced impairment of in vitro angiogenic activities in human umbilical vein endothelial cells (HUVECs). Res‐veratrol exposure is also associated with increased activation of Akt/eNOS together with a restoration of nitric oxide production in HUVECs exposed to oxLDL. Our study suggests that moderate consumption of red wine improves ischemia‐induced neovascularization in high‐cholesterol conditions by increasing the number and the functional activities of EPCs and by restoring the Akt‐eNOS‐NO pathway.— Lefevre J., Michaud, S.‐E., Haddad, P., Dussault, S., Ménard C., Groleau, J., Turgeon, J., Rivard A.
