The substantial reduction in rhythm disturbances and AMI in this setting appears to be offset by this potential increase in mortality and stroke.</p></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0045">Comments</span><p id="par0045" class="elsevierStylePara elsevierViewall">This systematic review presents the best available evidence on the controversial topic of the perioperative use of beta-blockers in cardiac or non-cardiac surgery.<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">1</span></a> Perioperative cardiovascular complications are an important concern because 2% of patients suffer major cardiac complications,<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">2</span></a> and 8% show evidence of significant myocardial injury.<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">3</span></a></p><p id="par0050" class="elsevierStylePara elsevierViewall">The perioperative use of beta-blockers was initially seen as a potential way to decrease the risk of perioperative cardiovascular complications, particularly after the publication of two RCTs with positive results.<a class="elsevierStyleCrossRefs" href="#bib0090"><span class="elsevierStyleSup">4,5</span></a> On the basis of this evidence, the first versions of the clinical practice guidelines recommended the use of beta-blockers in the perioperative period in patients undergoing non-cardiac surgery. Nonetheless, for various reasons, the strength and scope of these recommendations have decreased in later versions of the guidelines. First, the benefits of perioperative beta-blockers could not be reproduced in other RCTs. Second, the POISE-1 trial, which enrolled 9000 participants, showed that the use of beta-blockers decreased the risk of perioperative AMI but increased the risks of death, stroke, bradycardia and hypotension.<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">6</span></a> These adverse events were likely related to one of the major criticisms of the POISE-1 trial, namely starting long-acting beta blockers at high doses shortly prior to surgery.<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">6</span></a> Third, the validity of work led by the Dutch investigator Don Poldermans has come under scrutiny, and two RCTs (the DECREASE trials) with positive results have been retracted due to concerns about scientific misconduct.<a class="elsevierStyleCrossRefs" href="#bib0095"><span class="elsevierStyleSup">5,7</span></a> Consequently, the guidelines re-evaluated these data and excluded them from the background evidence used to set recommendations for perioperative beta-blockade.</p><p id="par0055" class="elsevierStylePara elsevierViewall">As an example, the American College of Cardiology (ACC)/American Heart Association (AHA) guidelines supported their recommendations by their own systematic review on this topic, from which they excluded the two DECREASE trials. The review identified 16 RCTs including 12 043 participants and the pooled results showed that prophylactic beta-blocker use resulted in 17 fewer cases of AMI, at the cost of four excess strokes and six deaths for every 1000 patients.<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">8</span></a> Nevertheless, the review identified major limitations: no valid trials assessed beta-blockade that was started more than 24 hours before surgery, and very few trials assessed agents aside from metoprolol. Therefore, the ACC/AHA guidelines advise against initiating beta-blocker therapy in the 24 hours before surgery. Based on observational studies, starting beta-blocker therapy might be considered in patients at high cardiovascular risk or with reversible ischemia detected on stress testing.<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">8</span></a></p><p id="par0060" class="elsevierStylePara elsevierViewall">Importantly, the above discussion is mostly relevant to patients beginning beta-blockers de novo, and does not apply to patients previously treated with beta-blockers. As withdrawal of chronic therapy is associated with an increase in the risk of cardiovascular events and death, beta-blocker therapy should be continued, although modification of perioperative doses or discontinuation may be required to address changing clinical circumstances such as hypotension, bradycardia, or massive blood loss.</p><p id="par0065" class="elsevierStylePara elsevierViewall">The current European Society of Cardiology guidelines on non-cardiac surgery only recommend beta-blocker therapy (preferably with atenolol or bisoprolol based on observational studies)<a class="elsevierStyleCrossRefs" href="#bib0115"><span class="elsevierStyleSup">9-11</span></a> in high-risk patients undergoing high-risk surgery.<a class="elsevierStyleCrossRef" href="#bib0145"><span class="elsevierStyleSup">12</span></a> Based on clinical judgment and evidence from small trials, beta-blockers should be initiated and titrated in order to achieve a heart rate between 60 and 70 bpm and to avoid a systolic blood pressure below 100 mmHg.<a class="elsevierStyleCrossRefs" href="#bib0135"><span class="elsevierStyleSup">13,14</span></a></p><p id="par0070" class="elsevierStylePara elsevierViewall">The clinical question posed here clearly needs to be answered with new randomized controlled trials to determine (1) which patients derive benefit from beta-blocker therapy in the perioperative setting; (2) if there is a class effect or whether there is a single best beta-blocker (if any) for this setting; (3) what is the best time to start beta-blockers, or what is the period of greatest risk; and (4) what are the optimum doses and/or hemodynamic targets (including blood pressure and heart rate) for beta-blocker therapy.</p><p id="par0075" class="elsevierStylePara elsevierViewall">In cardiac surgery, there are many situations in which beta-blockers are already indicated.
