Jackson and colleagues1 found an inverse association between light to moderate alcohol intake and risks of cardiovascular mortality in men with a history of stroke. However, among the plausible explanations of this beneficial action, the anti-inflammatory effects of alcohol were not clearly mentioned.
There is a growing body of evidence that moderate alcohol consumption decreases the levels of C-reactive protein2 and that the baseline concentration of such a marker of inflammation predicts the risk of future cardiovascular events.3,4 Furthermore, increased levels of C-reactive protein seem to be associated with a worse outcome in patients with ischemic stroke.5 Thus, the protective effects of alcohol in men with a history of stroke could also be related to its anti-inflammatory activity.
