Beta Blocker Use Questioned in Non-Hea...(isk of cardiovascular complications foun...),Health

Date:11/10/2008

isk of cardiovascular complications found that 2.1 percent of those getting a moderate daily dose of bisoprolol, a widely used beta blocker, suffered heart attacks or died of heart disease, compared to 6 percent of those not getting the beta blocker, Poldermans reported.

What might help decide the issue would be "a study to clarify dose and regimen" of beta blockers before surgery, he said. But such a study might be difficult to do, because the dangers of high-dose beta blockers are clear, Poldermans said.

"I would be very careful with high doses of beta blockers," he said. "There could be an increased risk of stroke. But a low dose is safe, so why take a high dose?"
