What is the association between heavy alcohol consumption and risk for stroke?
Heavy alcohol consumption has been associated with an increased risk for stroke. A meta-analysis of 35 observational studies found that consumption of 60 g alcohol per day was associated with a 64% increased risk for all stroke (RR, 1.64; 95% CI, 1.39 1.93), a 69% increase for ischemic stroke (RR, 1.69; 95% CI, 1.34 2.15), and more than doubling for hemorrhagic stroke (RR, 2.18; 95% CI, 1.48 3.20).
