The Importance of Beta Blockers In The Treatment of Heart Failures

Beta-blockers are effective in treating and preventing heart failure. The medicine provides patients who are suffering from heart failure with these four benefits:

  • Relaxes the heart 
  • Decreases the production of toxins produced by the body during heart-failure 
  • Slows down the heart rate 
  • Improves heart’s pumping ability 

Your doctor might prescribe you a beta-blocker in the following cases:

  • Heart attack
  • Systolic Heart failure 
  • High Blood Pressure 
  • Tachycardia, fast heart rate 
  • Arrhythmia, irregular heartbeat 

There are many types of beta-blockers, but only three of them are FDA-approved:

  • Bisoprolol (Zebeta)
  • Carvedilol (Coreg)
  • Metoprolol (Toprol)

Beta-blockers can be prescribed by your doctor with other medications like:

Aldosterone Antagonists 

This medication helps block the hormones that can worsen your heart failure. It make your kidney generate more urine so all the salt and other toxins are flushed out of the body. This also helps the heart pump better. 

Angiotensin Receptor-Neprilysin Inhibitors (ARNI)

This combination of medicine helps pump your blood better, and relaxes the heart to a certain extent. It reduces the symptoms so that you can engage in day-to-day activities without any hindrances. 

Sodium-glucose Cotransporter 2 Inhibitors (SGL2T-i)

This medicine not only helps your heart pump better but also if you suffer from diabetes, then it helps lower your blood sugar level. 

How To Take Beta-Blockers? 

You can take these medicines either with your meals, at bedtime or in the morning. Your doctor will instruct you on the appropriate time to take these medicines. 

Beta-blockers shouldn’t be used if you have low blood pressure or a slow pulse. If you have a cough or cold then your doctor will normally treat the congestion before prescribing you the medicine. 

You might be asked to record your pulse rate daily, by your doctor. If your pulse rate is below 100, then please consult your doctor if you should or shouldn’t take the beta-blocker on that specific day. 

Do not stop taking the medicines unless you have prior confirmation from your doctor to the same. You might at times think that the medicines aren’t working and just making it worse, but the beta-blocker takes a little time to show effective results. If you have any unusual symptoms then immediately consult your doctor. 

Side-Effects of Beta Blockers

  • Fatigue or tiredness 
  • Cold hands and feet

  • Sudden weight gain
