A peri-operative statin update for non-cardiac surgery. Part II: Statin therapy for vascular surgery and peri-operative statin trial design

Abstract

This is the second of two review articles evaluating peri-operative statin therapy. In surgical patients, the utility of peri-operative statin therapy is strongly suggested by retrospective studies, although it is probably overestimated, as important confounding factors have not been controlled for and hence the literature is considered to be currently inconclusive. This review examines the potential mechanisms and indications for peri-operative statin protection, the efficacy of acute peri-operative beta-blockade in addition to statin therapy, the effect of peri-operative statin therapy withdrawal and the implications of comorbidities associated with peri-operative cardiovascular risk on statin therapy. Recommendations concerning appropriate dosing, duration, therapeutic targets and necessary investigations when prescribing peri-operative statins are made. Peri-operative study design recommendations are suggested, so that future meta-analyses may be more informative. Recommendations are made regarding retrospective reporting of statin studies to minimise the bias inherent in a number of the current retrospective studies on this subject. © 2008 The Author.
