Prayer Helps Heart Patients October 26, 1999 - Heart patients who had someone praying over them without their knowledge suffered 10% fewer complications, a study found. "It's potentially a natural explanation we don't understand yet. It's potentially also a supernatural mechanism," said William Harris, a heart researcher who was lead author of the study. Harris and other researchers at the Mid America Heart Institute studied 990 patients admitted during a year to their coronary care unit. The patients were randomly divided into 2 groups. In one, patients were prayed for daily by community volunteers for 4 weeks; the other patients didn't have anyone assigned to pray for them. The patients, their families and their caregivers were not even told they were in a study. The volunteers were told only the first names of the patients and asked to pray daily for their speedy recovery with no complications. After 4 weeks, the prayed-for patients had suffered about 10% less complications, ranging from chest pain to cardiac arrest, researchers reported in Monday's issue of the Archives of Internal Medicine, published by the American Medical Association. The findings suggest that prayer might be an effective addition to standard medical care. At the same time, Harris acknowledged that his study had limitations. Among other things, many patients in the comparison group undoubtedly had friends and relatives praying for them, too. Both studies tallied complications using their own scoring systems, said Dr. Herbert Benson. Other studies have found no apparent benefits to being prayed for, and in one, prayed for patients actually fared worse, Benson said. Benson said medical research has shown that people who believe in God or in prayer generally fare better than those who don't. What remains unproven is whether prayer itself makes a difference, he said.
