Randomized Controlled Trial Comparative Study Clinical Trial
Effect of bisoprolol on perioperative complications in chronic heart failure after surgery (Cardiac Insufficiency Bisoprolol Study II (CIBIS II)).
In patients with coronary artery disease undergoing noncardiac surgery, beta-blockers decrease perioperative mortality and nonfatal myocardial infarction. It is presently unknown whether beta-blockers reduce perioperative risk in patients with chronic heart failure. Thus, data of the CIBIS II study were analyzed regarding the effect of bisoprolol on perioperative outcome in patients with moderate to severe heart failure. ⋯ Neither postoperative hospital admission (placebo, 24.4%; bisoprolol, 34.5%, p = 0.17) nor time to postoperative hospital admission (placebo, < or =30 days, n = 2; 31-180 days, n=11; >180 days, n = 6; bisoprolol, n = 9/ 10/11; p = 0.14) were reduced by bisoprolol. Compared to coronary artery disease, perioperative beta-blockade has little effect in patients with chronic heart failure. Therefore, a controlled randomized trial with perioperative beta-blocker treatment in heart failure patients is warranted to further test this hypothesis.
