Cutting off the blood flow to the arm by repeatedly inflating a blood pressure cuff appears to reduce the amount of tissue damaged during a heart attack, a new Danish study shows.
In a study of 142 patients being rushed to a hospital for treatment of severe heart attacks, the amount of heart tissue saved for those who got the treatment, called induced ischemia, was 30 percent greater than for those who didn't, according to a report in the Feb. 27 issue of The Lancet.
"For patients being transported to the hospital for acute myocardial infarction [heart attack], we inflated the blood pressure cuff for five minutes, relaxed it and repeated it four times," said study author Dr. Hans Erik Botker, a professor of cardiology at Aarhus University Hospital in Skejby.
