Blood-pressure drug risk found
One of the hottest-selling drugs for treating high blood pressure actually may increase the risk of heart attacks, Canadian researchers say.

Their article, published in the British Medical Journal, warns that although angiotensin II receptor blockers, or ARBs, reduce blood pressure, they do not reduce the risk of heart attack.

In fact, ARBs appear to increase the risk by almost 20 per cent.
