Statins in the perioperative period.

Area of Science:

• Cardiology
• Perioperative Medicine
• Clinical Evidence Synthesis

Background:

• Conflicting evidence exists regarding perioperative statin benefits in non-cardiac surgery.
• Studies vary in data sources, outcome definitions, and timing of statin administration (preoperative vs. perioperative).

Purpose of the Study:

• To review clinical evidence on the benefits of statin therapy during the perioperative period of non-cardiac surgery.
• To evaluate the impact of continuing versus initiating statin therapy on patient outcomes.

Main Methods:

• Review of meta-analyses from prospective observational studies.
• Analysis of recent large prospective cohort studies.
• Examination of available randomized controlled trials (RCTs) on statin use in non-cardiac surgery.

Main Results:

• Two recent cohort studies indicate perioperative statin use is linked to lower 30-day mortality and fewer postoperative complications, especially cardiac ones.
• RCTs have not confirmed benefits of initiating statins in statin-naïve patients for cardiovascular risk reduction.
• One RCT showed preoperative statins reduced myocardial necrosis and major adverse cardiovascular events in patients on long-term statin therapy.

Conclusions:

• Resuming statin therapy is crucial for patients with established atherosclerotic cardiovascular disease undergoing non-cardiac surgery.
• Initiating statin therapy in statin-naïve patients for non-cardiac surgery requires further evidence-based research.
