Are perioperative statins beneficial for cardiac surgery?

The use of perioperative statins has been proposed as a measure to reduce morbidity and mortality in cardiac surgery. However, their clinical role is controversial. Searching in Epistemonikos database, which is maintained by screening multiple databases, we identified 36 systematic reviews comprising 92 primary studies addressing the question of this article, including 22 randomized trials. We extracted data, combined the evidence using meta-analysis and generated a summary of findings following the GRADE approach. We concluded perioperative statins probably do not decrease mortality in cardiac surgery and it is unclear if they have any benefit because the certainty of the evidence is very low.
