Many people who have or are at risk for heart problems take drugs called beta blockers to reduce the risk of future heart issues. This measure shows whether surgery patients who were already taking beta blockers before coming to the hospital were give beta blockers during the time just before and after their surgery.
Why this is important:
It is often standard procedure to stop patients' usual medications for awhile before and after their surgery. But if patients who have been taking beta blockers suddenly stop taking them, they develop have heart complications such as a fast heart beat. For these patients, staying on beta blockers before and after surgery makes it less likely that they will have heart problems.
