    Beta blockers may offer little against heart attack, stroke Commonly prescribed drugs called beta blockers fail to protect against heart attacks and strokes even while helping to control heart rate and blood pressure, researchers report in the Oct. 3 Journal of the American Medical Association. Beta blockers also didn’t lessen the odds of a heart-related death, in heart attack patients or others at risk, over a median follow-up of 44 months. The American Heart Association had previously discouraged the long-term use of beta blockers as a post–heart attack treatment beyond three years. The new findings further dim the prospects for...

    Scientists have discovered a genetic mutation that might extend the lives of many African Americans after heart failure by mimicking a common class of drugs called beta blockers. The findings could explain why clinical trials of the drugs have shown little benefit to African-American patients. The heart doesn't stop beating during heart failure. Instead, it stops pumping blood efficiently. The condition can be caused by a number of diseases--including diabetes and hypertension--that keep the heart from filling with blood or decrease blood flow from the heart to the rest of the body. As the heart falters, the body releases adrenaline...

    Beta blockers, the most commonly used drugs for treating high blood pressure unaccompanied by other cardiovascular disease, are probably less effective than other drugs used for the same purpose, new research says. The work examines the results of 13 randomized trials and concludes that the drugs, which have been the first-line treatment for hypertension for at least 25 years, produce a higher risk for stroke when compared with other drugs used for the same purpose. Dr. Lars H. Lindholm, the lead author on the study, which was published in Lancet online on Oct. 18 and in print on Saturday, emphasized...

    A "FIRST-line" anti-high blood pressure drug is leaving patients at far greater risk of suffering strokes than if they take other medication for the condition, according to a major study. People taking the commonly prescribed beta-blockers had a 16 per cent higher chance of stroke than if they took other drugs to treat high blood pressure, according to the findings by Swedish researchers. One particular beta-blocker, atenolol, was found to be associated with a 26 per cent higher stroke risk. Medical experts warned yesterday that patients should not stop taking beta-blockers, which are beneficial for a range of other conditions....
