A new study has shown that beta-blockers which for decades have been used to treat heart related diseases, strokes, hypertension and cardiac arrest may not be effective after all. Beta-blockers work by blocking adrenalin receptors in the brain which are readily activated once the body is stressed up.
Recently, Journal of American Medical Association published that out of 45,000 patients with prior heart disease, coronary artery diseases or coronary related ailments, those that use beta-blockers did not show much significant reduction in the rate of heart attacks. This latest publication which tries to refute an age long belief and convention will throw up a fresh medical challenge to medical practitioners on whether or not to continue prescribing the beta-blockers. 'This is a very compelling study that will shake up the conventional wisdom that exists on the role of beta blockers in the management of patients with heart diseases' said a Cardio-vascular specialist Dr. Randel Thomas who works with Mayo clinics. Some doctors said they were impressed that effectiveness of beta-blockers are being questioned at this critical time seeing that its use has been 'written in stone' for years. However, others believed that using a non-randomized data is not as reliable as using a randomized drug trial. Reaching a common ground continues
