A study about perioperative beta-blockers came out in the NEJM. Here are some articles showing divergent headlines:
Study: Beta Blockers Don’t Help All
Beta blockers don’t help people with low heart risk after surgery
Cardio Drugs May Prevent Surgery-Linked Heart Attack
Here is the real conclusion:
Perioperative beta-blocker therapy is associated with a reduced risk of in-hospital death among high-risk, but not low-risk, patients undergoing major noncardiac surgery. Patient safety may be enhanced by increasing the use of beta-blockers in high-risk patients.
