Heart Drug Setback

DALLAS () -- A new substance developed to help stop heart attacks in progress has shown promise in hospital studies but also causes kidney damage, and researchers are going back to the laboratory.


Patients given poloxamer 188, also known by the brand name RheothRx, had smaller heart attacks and less heart muscle damage, according to the study. Their hearts also pumped more efficiently compared with people who received a dummy medication, according to the study, published Thursday in the American Heart Association journal Circulation. All of the patients were given standard clot-busting drugs as well.
