Stop using this common heart drug; it could be dangerous for your health

Scientists warn if you are taking this drug for your heart, you need to immediately stop.

For decades, beta blockers have been one of the routine drugs many patients receive after a heart attack. They are widely used for cardiac conditions and have long been considered a standard part of recovery after myocardial infarction. 

But a major 2025 clinical trial suggests that many people who have an uncomplicated heart attack and still have good heart function may not benefit from taking them at all.

A massive international study could upend 40 years of heart attack treatment.

Researchers found that beta blockers—routinely prescribed after uncomplicated heart attacks—offered no real benefit for patients whose heart function remained normal, despite being given to millions worldwide.

Even more surprising, women taking the drugs faced a higher risk of death, repeat heart attack, or hospitalization for heart failure compared to women who didn’t receive them.

The findings come from the REBOOT Trial, a large international study led by senior investigator Valentin Fuster, MD, PhD, president of Mount Sinai Fuster Heart Hospital and general director of Spain's Centro Nacional de Investigaciones Cardiovasculares, or CNIC.

Moreover, new findings were presented during a session at the European Society of Cardiology Congress in Madrid.

The study was published in The New England Journal of Medicine.

Experts advise that the heart is the most sensitive organ and one should properly consult with doctor or specialist for taking any prescribed medicine.
