In recent news, research now suggests that beta blockers do not actually prevent heart attacks and strokes in patients who already suffer from heart disease. Beta blockers are prescribed by doctors to treat high blood pressure, chest pains, and other heart problems. They are also sometimes used to prevent heart attacks in patients who have had past heart attacks.
The study looked at 45,000 patients who have had a previous history of heart attacks, coronary artery disease, or risk of coronary artery disease. What was found was that beta blockers did not have a significant rate of lowering heart attack, stroke, or cardiac death than with those who were not on the medication. It is an interesting study, but doctors will not stop prescribing beta blockers just yet. There will need to be more substantial evidence against the fact in the future in order for beta blockers to stop being used.
