Does Prayer Help Others Heal?
Study's Mixed Results May Pave the Way for Future Research
July 14, 2005 -- A new study of prayer and heart health has researchers asking more questions than they can answer right now.
The findings didn't show a benefit for the main result measured. But that may not be the end of the story.
"This is a first step, not a final, conclusive work," researcher Mitch Krucoff, MD, FACC, FCCP, tells WebMD.
"We are very early in our scientific understanding of how important prayer works for healing," he says.
Krucoff is a professor of medicine and cardiology at Duke University Medical Center. He also directs the cardiovascular devices unit at the Duke Clinical Research Institute. The study appears in The Lancet.
The study included 748 people. They were due to get a heart procedure -- a cardiac catheterization -- to check for blocked arteries. Three out of four also got other procedures to reopen those arteries.
The researchers asked a dozen congregations from a variety of faiths around the world to pray for 371 of the patients. The other 377 patients were not put on official prayer lists.
Everyone got standard medical care. Some patients also got bedside music, imagery, or touch therapies.
The patients were followed for six months.
All groups had similar outcomes in the study's main measurement: a combination of major in-hospital heart problems, rehospitalization within the next six months, or death.
But other measures showed possible benefits.
While there was no positive result on prayer for the main result, Krucoff says there was a suggestion of benefit in other specific areas.
Emotional distress before the heart procedure and death six months after the procedure were lower in the music/imagery/touch group.
"These may be the world's most ancient healing traditions, but the clinical science we're using is what we would use for evaluating the most modern of therapeutics," says Krucoff.
"What real science in this area does is set the stage for us to learn something and then continue to investigate until we really begin to understand the role of the human spirit in the context of high-tech cardiovascular care," he says.
