Benefits might vary with ­different statins
The studies evaluated in this ­meta-analysis used various statins and dosing regimens, which could have affected the results. However, sensitivity analyses found similar benefits across different types of statins. In addition, most of the included trials used high doses of statins, which minimized the potential discrepancy in outcomes from various dosing regimens. And while the included studies were not perfect, Navarese et al1 used reasonable methods to identify potential biases.

CHALLENGES TO IMPLEMENTATION
No barriers to earlier start
Implementing this intervention may be as simple as editing a standard order. This meta-analysis also suggests that the earlier the intervention, the greater the benefit, which may be an argument for starting a statin when a patient first presents for evaluation for ACS, since the associated risks are quite low. We believe it would be beneficial if the next update of the ACC/AHA guidelines7 included this recommendation.
