In a new study, researchers report that a class of heart medications called beta-blockers can have a helpful, or harmful, effect on the heart, depending on their molecular activity. The study, which appears in the journal Circulation Research, found that beta-blockers that target both the alpha- and beta-receptors on the heart muscle offer the most benefit to cardiac patients, while those that target only the beta-receptors can actually undermine the structure and function of the heart....

Their findings, they said, suggest new approaches to prevent or reverse heart failure, which affects two to three million people in the U.S. The team reports its findings in the August 2005 issue...
