What is the effect of preoperative beta blockers on inhospital mortality rate in patients with LVEF less than 30%?
The effectiveness of preoperative beta blockers in reducing inhospital mortality rate in patients with LVEF less than 30% is uncertain. However, an analysis of data from 629 877 patients reported a mortality rate of 2.8% in those receiving beta blockers versus 3.4% in those not receiving. Meta-analysis of available data did not show an improvement in outcomes with perioperative beta blockers, however observational analyses suggest that preoperative beta-blocker use is associated with a reduction in perioperative deaths.
