St. Louis, March 29, 2005 -- Scientists have identified an important link between kidney damage and cardiac problems, creating new possibilities for treating the primary cause of death in kidney disease patients. Researchers tracked a chain reaction that leads from kidney damage to weakening of the skelet...Lack of clinical trial participation may contribute to lower survival rates
