How to Survive Your Hospitalization: Drink Coffee

Coffee reduces the risk of death after acute myocardial infarction: a meta-analysis.

Drinking coffee regularly after an acute myocardial infarction was found to be associated with a reduced risk of mortality. Coron Artery Dis. 2016 Nov;27(7):566-72.

Comment: This study found that routine heavy coffee drinkers (over 2 cups a day) had a lower mortality after acute myocardial infarction than routine light coffee drinkers (1 to 2 cups a day), who had a lower mortality after acute myocardial infarction than noncoffee drinkers. The risk reductions observed were significant: heavy versus light (31% risk reduction), heavy vs noncoffee drinkers (46% reduction), and light vs noncoffee drinkers (21% reduction). 

Should we allow, and possibly even encourage patients after an acute myocardial infarction to drink coffee?
