Two Drinks a Day Cut Stroke Risk: Study

By    |   Tuesday, 27 May 2014 04:11 PM

Here's another reason to drink a toast to your health. New research has found drinking up to two alcoholic beverages each day might reduce stroke risk.
 
But heavier drinking — three or more alcoholic beverages daily — appears to increase the risk of hemorrhagic stroke, according to the new analysis of studies, published online in the International Journal of Cardiology and reported by MedPage Today
 
Lead Yu-Hao Zhou, of Shanghai Seventh People's Hospital, and colleagues speculated that "light alcohol intake is associated with a reduced risk of ischemic events because low alcohol concentrations might increase HDL cholesterol levels, decrease platelet aggregation, increase fibrinolysis, and decrease plasma fibrinogen levels."
 
On the other hand, they added, "heavy alcohol intake is associated with an increased risk of hemorrhagic events because heavy alcohol intake potentially results in high blood pressure, reduced platelet aggregation, and enhanced fibrinolysis through increased secretion of plasminogen activators from endothelial cells."
 
Past studies have offered conflicting findings. Some have shown that light-to-moderate alcohol consumption is associated with lower risks of cardiovascular disease and ischemic stroke, but others have shown that having even a couple drinks a day might increase the risks of hypertension and atrial fibrillation, two strong stroke risk factors.
 
The new findings are based on an analysis of 27 studies involving more than 1.4 million people conducted in the U.S. (11), Europe (nine), Japan (four), and China (three).
 
Compared with abstinence, the combined findings of the studies showed that low alcohol intake was associated with reduced risks for stroke and stroke-related deaths. Moderate intake was not associated with any of those benefits, and heavy intake was associated with an increased risk of suffering a stroke.
