Abstract
The effect of alcohol ingestion on primary hemostasis was investigated in fasting healthy humans. Primary hemostasis was measured with the template bleeding time and platelet aggregation assayed with the turbidometric method. Blood was collected to study coagulation and fibrinolysis. 1 h after ingestion of 2 ml/kg body weight of 40% alcohol the plasma alcohol concentration was 19.3 ± 1.6 mmol/l. At this time there was a significant prolongation of the bleeding time accompanied by an impairment of platelet responsiveness to both collagen and ADP. A prolongation of the bleeding time and impairment of platelet function was also found 2 h after alcohol ingestion. Ingestion of this amount of alcohol did not affect parameters of coagulation or fibrinolysis. The data indicate that primary hemostasis is impaired in man after ingestion of moderate amounts of alcohol. This may explain the favorable effect of moderate alcohol consumption on ischemic heart disease but indicates an increased risk for patients with bleeding.
