MIAMI, Fla. -- A study suggests a slight heart benefit to chelation therapy, but cardiologists aren't convinced it should become mainstream.
Chelation is a process that removes certain metals from the bloodstream. It's considered an alternative therapy and is costly, as much as $5,000 per treatment.
The new study, sponsored by the National Institutes of Health, found a slight benefit of chelation therapy in terms of reducing the rate of death and heart problems.
The chelation infusion also contained vitamin C and A blood thinner. Both may have skewed the results. Experts say the research is preliminary.
This study is from Mount Sinai Medical Center in Miami, and was presented at the American Heart Association's Scientific Sessions.
