Heart failure with reduced ejection fraction is a significant driver of morbidity and mortality. There are common misconceptions regarding the disease processes underlying heart failure and best practices for therapy. The terms heart failure with reduced ejection fraction and left ventricular systolic dysfunction are not interchangeable terms. ⋯ Marginal blood pressure is not a relative contraindication to optimal guideline directed medical therapy. Guideline directed medical therapy should be continued even if ejection fraction improves. There are other therapies that provide significant benefit besides the four key medications in guideline directed medical therapy.

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.

Excess mortality remains the cornerstone concern despite dual antiplatelet therapy (DAPT) after acute coronary syndrome. Some data suggest that shorter periods than 12 months of DAPT diminish bleeding risks yet still provide adequate vascular protection and improving survival. However, the precise timing of deaths after acute coronary syndrome has not been mapped in many studies. This knowledge may be critical for defining optimal treatment duration. ⋯ Focusing on mortality reduction, this large data set may support a shorter than 12 months' duration of DAPT.
