Influenza can cause a significant burden on patients with coronary artery disease. This meta-analysis assessed the effectiveness of influenza vaccination in patients with acute coronary syndrome and stable coronary artery disease. ⋯ Influenza vaccine is a cheap and effective intervention to reduce the risk for all-cause mortality, cardiovascular mortality, major acute cardiovascular events, and acute coronary syndrome among coronary artery disease patients, especially in those with acute coronary syndrome.

Our purpose was to examine the association between beta-blocker dose and mortality following acute myocardial infarction. ⋯ Any beta-blocker dose was associated with significant mortality reduction following acute myocardial infarction compared with no treatment. Doses >25%-50% of the currently recommended target dose were associated with maximal mortality reduction within the first year after acute myocardial infarction, suggesting that higher doses are unnecessary.
