Can Beta Blockers Cause Heart Failure

Major cardiac effects caused by beta blockade include the precipitation or worsening of congestive heart failure, and significant negative chronotropy.

Can beta blockers weaken your heart?

While beta blockers can reduce damage to the heart by taking the strain off, Dr. Shill explains that if taken incorrectly they could actually weaken the heart. When not taken as prescribed, they can do more harm than good.

Why you shouldn't take beta blockers?

It’s dangerous to stop taking beta-blockers suddenly, even if you’re experiencing side effects. When you take beta-blockers, your body gets used to your heart’s slower speed. If you stop taking them suddenly, you could increase your risk of a serious heart problem, such as a heart attack.
