A new study suggests thousands of heart attack patients may be taking beta blockers unnecessarily — and at risk. For decades, the daily pills have been standard treatment, but fresh research shows they may not help survival.

The Spanish trial followed over 8,500 patients. Results revealed no clear benefit for men or women with healthy heart function. Alarmingly, women on beta blockers faced a higher risk of death, repeat heart attacks, or heart failure. “These findings will reshape international guidelines,” said Dr. Valentin Fuster.

Experts believe medical progress has changed the need for beta blockers. Modern treatments like stents and rapid artery reopening mean the original benefits may no longer apply. “While we often test new drugs, we rarely question older ones,” added Dr. Borja Ibáñez.

With side effects including fatigue, nausea, and sexual dysfunction, many patients could now be spared years of discomfort.
