start beta-blockers earlier before surgery
New guidelines say to start beta-blockers earlier before surgery.
Beta-blockers are often given before some noncardiac surgeries to high-risk patients. These are often patients with ischemia on pre-op tests...cardiovascular disease...or multiple risk factors.
But it can be harmful to start a HIGH-dose beta-blocker on the day of surgery. Blood pressure and heart rate can fall too much...and lead to more stroke and death.
