Statins and noncardiac surgery: Current evidence and practical considerations

Author and Disclosure Information


Vascular surgery is associated with a high risk of peri­operative morbidity and mortality that is partly attributable to inflammatory stress induced by the surgical procedure. Preoperative initiation of a long-acting statin is a strategy intended to reduce the inflammatory stress response and the excess risk associated with vascular surgery. The Dutch Echocardiographic Cardiac Risk Evaluation Applying Stress Echo III demonstrated significant reductions in perioperative myocardial ischemia and the composite end point of myocardial infarction or cardiovascular death with extended-release fluvastatin (relative to placebo) initiated 30 days prior to vascular surgery. These benefits were achieved with no increase in liver dysfunction, evidence of myopathy, or other side effects. Observational data suggest that perioperative statin use is associated with improved recovery from acute kidney injury after high-risk vascular surgery and with improved long-term survival in patients undergoing such surgery.


  • The inflammatory and oxidative stress induced by vascular surgery can be blunted by statin therapy.
  • Statin therapy started preoperatively can reduce the incidence of myocardial ischemia and the level of inflammatory markers in patients undergoing high-risk vascular surgery.
  • The purpose of perioperative statin use should be reduction of the inflammatory stress response to surgery, with the long-term goal being achievement of target lipid levels.
  • A long-acting statin is preferred preoperatively to best extend the anti-inflammatory effects into the postoperative period. Statin therapy should be continued postoperatively, if possible, to avoid deleterious acute withdrawal effects.



Current uncertainty over the best approach for preventing fatal perioperative myocardial infarction (MI) lies in our inability, despite sophisticated testing methods, to detect unstable coronary plaque prior to surgery. Unstable plaque can be present in patients with coronary lumina that appear normal on coronary angiography. Therefore, reliance on medical therapy to blunt inflammation is currently the best practice for minimizing the risk that unstable plaque poses.

Perioperative use of statins is a cornerstone of such therapy. This article briefly reviews the rationale for perioperative statin use in the setting of noncardiac surgery, presents the latest evidence on the clinical effects of perioperative statin use, and considers the potential role for statins in promoting recovery from acute kidney injury after vascular surgery.


Fatal perioperative MI has two potential origins. 1,2 One is a culprit coronary plaque that fissures and ruptures, causing a cascade of thrombogenic events (hemorrhage and thrombosis) inside the vessel wall, culminating in an MI. Less often, fatal perioperative MI results from long-lasting myocardial ischemia (a demand/supply mismatch of oxygen), typically as a consequence of a fixed coronary stenosis.

In nearly half of patients with fatal MI, coronary inflammation is a key contributor. In the perioperative setting, surgical stress induces the release of inflammatory cytokines that disrupt smooth muscle cells in the endothelium and contribute to disruption of a non­obstructing coronary plaque, predisposing to acute thrombus formation.

Risk reduction depends on pathophysiology

Strategies for minimizing the risk of perioperative MI depend on the pathophysiology involved. In the case of oxygen demand/supply mismatch as a result of flow-limiting stenosis, a beta-blocker and coronary revascularization, if possible, may be useful.

In the more common case of unstable plaque, a multifactorial strategy appears optimal, involving the following:

  • Statin therapy to reduce coronary inflammation
  • Aspirin to blunt the prothrombotic milieu postoperatively
  • Chronic low-dose beta-blockade to decrease myocardial oxygen demand or inhibit plaque rupture.

A particular role for statins

Ridker et al found that patients with an acute coronary syndrome who experience a decline in high-sensitivity C-reactive protein (hsCRP) level after treatment with a statin have improved clinical outcomes compared with those whose hsCRP level remains high, regardless of their resultant low-density lipoprotein (LDL) cholesterol level. 3

Among surgical patients, those most at risk for poor cardiovascular outcomes are those who undergo vascular surgery. In Europe, the cardiovascular death rate in such patients is approximately 2%. 4

Retrospective cohort data and data from randomized clinical trials have demonstrated reductions in perioperative cardiac complications with statin use in patients undergoing various types of noncardiac vascular surgery. 5–9 In light of these data, my colleagues and I recently undertook a prospective study to examine the effect of perioperative statin use on cardiovascular complications in patients undergoing vascular surgery. 10 Key details and findings are surveyed in the following section.


The Dutch Echocardiographic Cardiac Risk Evaluation Applying Stress Echo III (DECREASE III) was conducted at a single center (Erasmus Medical Center, Rotterdam, the Netherlands) in a randomized, double-blind, placebo-controlled manner. 10
