Novel uses for statins in surgical patients

BackgroundAside from their cholesterol-lowering effects statins are known to have a range of other ‘pleiotropic’ effects. We present an overview of the basic science behind these effects and then review clinical trials and the current role of statins relevant to modern surgical practice.MethodsA systematic review of the literature was performed using the keywords surgery and the MeSH term for statins. All clinical studies relating to statin use in surgical patients were evaluated. An overview of the literature on statin use and cardiac outcomes was performed.ConclusionsStatins are safe and have a wide range of pleiotropic effects relevant to surgical practice. Strongest evidence for their clinical use comes in primary cardiac risk reduction in many types of vascular surgery. There is a large body of evidence showing their benefit perioperatively in high-risk vascular and cardiac surgery but the picture is less clear for low-risk patients. Further studies are needed to evaluate exact dosage regimes and timing of administration. Novel uses of their anti-inflammatory properties in sepsis and vasomotor properties in subarachnoid haemorrhage are being further investigated by randomised trials.
