What is the risk of recurrent stroke associated with alcohol consumption?
High alcohol intake (>60 g/d) has been identified as an independent risk factor for stroke recurrence at 90 days in minor stroke/TIA. The EPIC-CVD observational case-cohort study (European Prospective Investigation into Cancer and Nutrition-CVD) identified an ischemic stroke HR of 1.47 in alcohol consumption of 30.0 to 59.9 g/d and an HR of 2.17 in alcohol consumption of 60 g/d. Compared with lifetime abstainers, alcohol consumption of <12 g/d (1 drink a day based on US conversions) is associated with the lowest risk for mortality.
