How important is a beta blocker in the treatment of heart attack patients?

Very important: Beta blockers have been shown to keep the heart beating efficiently and effectively, and several studies have shown improved outcomes. There are many different beta blockers available, so a person should discuss with their doctor a balance between effectiveness, side-effects, and cost.

Very important: Assuming there is no contraindications to their use, beta blockers can decrease mortality after having a heart attack. They are also useful in decreasing blood pressure. For every increase in systollic BP (top number) by 20 and diastolic BP (bottom number) by 10 above 130/80, mortality from heart disease doubles, but not everyone can take beta blockers. Be sure to talk it over with you doctor.
