Beta Blockers Don't Stop Heart Attacks? Harvard Medical School Study
Published: Oct 03, 2012
New research suggests that beta-blocker pills don't prevent heart attacks, strokes or cardiac deaths in patients with heart disease, but doctors are torn over whether there's enough in the study to make them want to stop prescribing the drugs. Beta blockers have been a standard heart medication for decades. The study, published in the Journal of American Medical Association, looked at nearly 45,000 patients with prior heart attacks, coronary artery disease or risk factors for coronary artery disease, and found that those on beta blockers didn't show significantly lower rates of heart attack, stroke or cardiac death than those not on the medication.
