High dose of red wine elicits enhanced inhibition of fibrinolysis.

ABSTRACT

BACKGROUND AND DESIGN: The purpose of this randomized controlled cross-over study was to determine the acute effects of high doses of alcoholic beverages on circulating markers related to atherosclerosis and fibrinolysis. METHODS: Twenty-two healthy men consumed a high dose (8.1+/-0.9 dl) of alcohol-containing red wine and dealcoholized red wine, and an equal ethanol dose of cognac (2.4+/-0.3 dl). Blood samples were taken before and shortly after interventions. RESULTS: Red wine, unlike dealcoholized red wine and cognac, increased tissue plasminogen activator inhibitor-1 levels significantly, indicating an acute inhibition of fibrinolysis after a high dose. CONCLUSION: Findings may explain the increased risk of cardiovascular mortality among binge drinkers.
