Sažetak
Studies of the cardioprotective effects of wine are mainly focused on red wines, due to their much higher content of bioactive compounds relative to white wines. Although some studies indicate a cardioprotective effect of white wine, there is no clear consensus on the existence of additional benefits of white wine over ethanol. The aim of this study was to determine and compare the effects of moderate consumption of white wine and ethanol on the survival of rats subjected to surgically induced myocardial infarction (MI). Male Sprague Dawley rats (n = 74) were randomized into three groups: water only, white wine or a 13% v/v ethanol/water solution. After a four-week drinking period, MI was induced by ligating the left anterior descending artery. The survival rate was highest in the wine group (72.2%), and lowest in the water only group (47.8%). There was no statistically significant difference in survival between the ethanol and water groups. An analysis linking drinking volumes to survival outcomes revealed that lower ethanol consumption was more prevalent in rats that survived, indicating an upper limit for the protective effects of ethanol. An opposite finding was noticed in the wine group, where no deaths occurred in rats with an average daily white wine consumption of approximately 10 mL or more. We conclude that moderate consumption of white wine has a positive effect on survival after a myocardial infarction, which cannot be attributed only to ethanol, but also to other white wine constituents.
