Beta-blocker pills are another group of medicines that are very effective for people with heart failure. The long name for these pills is beta-adrenergic blocking agents. Research studies have shown that beta-blockers improve heart function and can help people with heart failure feel better, live longer and go to the hospital less frequently.
Beta-blockers work by:
- Blocking the effects of harmful stress hormones (substances produced by your body that make heart failure worse and contribute to your symptoms).
They also control high blood pressure, prevent heart attacks, and help regulate the heart rhythm. However, beta-blockers are effective for heart failure even if you do not have high blood pressure or an irregular heart rhythm.
