Radiation Therapy May Help Mend a Broken Heart

WebMD Health News
Reviewed by Gary D. Vogin, MD

Jan. 24, 2001 -- Retired New Jersey funeral director Fred C. Iliff, 70, had been hospitalized repeatedly with heart problems for 10 years before undergoing the procedure that, he says, gave him his life back. He had had two unsuccessful angioplasties when his doctor suggested the implantation of tiny wire-mesh tubes known as stents in his blocked heart vessels to keep them open and clear.

"Before the stents, I was constantly popping nitroglycerin pills and using nitro patches because of chest pains. I just never bounced back after the angioplasties," Iliff tells WebMD. "Now, it's a whole new ball game. I am an active volunteer fireman, and I can keep up with my grandchildren. I was out shoveling snow yesterday. I can do anything I want to do, and the nitro patches are sitting in back of the closet somewhere."

Even a few years ago the use of coronary stenting was relatively rare, but stents are now used in more than half of the patients undergoing nonsurgical heart procedures such as angioplasty -- where doctors use a balloon-tipped catheter to open clogged coronary arteries.

Like Fred Iliff, many patients who have failed previous coronary interventions do amazingly well after stenting is performed, but around 20% to 30% experience reclogging of the arteries within six months of receiving the procedure. The rate is even higher for patients who receive angioplasty without stents.

But two new studies, published in the Jan. 25 issue of TheNew England Journal of Medicine, suggest that radiation therapy can help keep heart vessel blockage from recurring. The studies come just two months after the FDA approved two devices -- one designed to deliver gamma radiation therapy, the other beta radiation -- to prevent artery reclogging after angioplasty and stenting.

"With the FDA approval last year, and the commercial availability of this treatment coming early next month, it is likely that radiation will be used widely in this group of patients," Jeffrey W. Moses, MD, chief of interventional cardiology at Lenox Hill Cardiovascular Institute of New York, tells WebMD. "We have used radiation in close to 500 patients, and it has proven to be very successful."
