We read with interest the studies by Siddiqui et al1 and Lindenauer et al.2 Each report has, as its raison d’être, the supposition that perioperative β-blockade is the standard of care for the prevention of postoperative cardiac complications. Furthermore, both studies presume that physicians who do not prescribe β-blockers are not practicing good perioperative medicine. We wish to express the contrarian view that the evidence supporting the recommendation for perioperative β-blockade is insufficient and that a vast amount of research is still required in the field of perioperative risk reduction.
