Since decades Beta blockers have been prescribed to patients as a standard medication for heart, but this time, in a recent study it has been found that these pills are not effective for preventing heart attacks, strokes or cardiac deaths in patients suffering with severe heart diseases. However, it is still a matter of concern for the doctors to decide that whether this study actually directs them to stop prescribing these drugs or no.

This study has been published in the Journal of American Medical Association. While carrying it out, around 45,000 patients were analyzed; all victims of prior heart attacks. Some were either already hit by coronary artery disease else they had risk factors for the same.

As a result researchers found that there was hardly any difference in the risk level of patients who had been on beta blockers since long and who had not been given the medication at all. The rates of heart attack, stroke or cardiac death were almost similar in all of them.

As said by Dr. Randal Thomas, a cardiovascular specialist at the Mayo Clinic, "This is a very compelling study that has the potential to shake up the conventional wisdom that exists regarding the role of beta blockers in the management of patients with cardiovascular disease".
