TUESDAY, March 27, 2012 (HealthDay News) -- Patients over the age of 65 who have severe coronary artery disease fare better with bypass surgery than with minimally invasive angioplasty, a large, new study indicates.
Although there was no significant difference in mortality after one year, patients who had undergone bypass surgery had a 21 percent reduced risk of dying after four years compared to those who had received angioplasty, the researchers found.
"Here, individuals over the age of 65 had a survival benefit with surgery, so this may be a better choice for these individuals," said Dr. Nieca Goldberg, medical director of the Joan H. Tisch Center for Women's Health at NYU Langone Medical Center in New York City.
Goldberg was not involved with the study, which is to be presented Tuesday at the American College of Cardiology annual meeting in Chicago and simultaneously published in the New England Journal of Medicine.
The trend in cardiology more recently has been to favor angioplasty over surgery, explained study author Dr. William Weintraub.
During angioplasty, cardiologists insert a small "balloon" into the blocked vessel via a catheter. Once in place, the balloon is inflated to widen the vessel. The procedure can be done with or without placing a stent, a wire mesh scaffold that keeps the vessel propped open.
Coronary artery bypass surgery involves grafting part of a healthy vessel onto the blocked vessel to reroute blood flow, "bypassing" the blocked part of the vessel.
But Weintraub, who is chair of cardiology at Christiana Care Health System in Newark, Del., said he did not envision an immediate sea change in clinical practice as the result of these findings.
"People will give surgery another thought, especially for sicker patients," he said. "Rather than being a huge, huge change, this may switch it back a little."
Weintraub and his colleagues combined information from two large databases which, all told, included about 200,000 patients, all elderly and all with more than one blood vessel blocked.
About 86,000 underwent surgery and 104,000 had angioplasty. Of those who had angioplasty, 78 percent received drug-eluting stents, 16 percent received bare-metal stents and 6 percent had no stents.
Drug-eluting stents, considered state-of-the-art, ooze a drug out into the artery that prevents scar tissue from building up.
Patients undergoing surgery tended to have more complications such as diabetes, lung disease and heart failure, although the authors did adjust for these factors.
Although the study was not a randomized, controlled trial -- considered the gold standard of medicine because those studies randomly assign people to different treatments and compares them with those who are untreated -- it had several advantages, including the fact that it was looking at a "real-world" population in real time, said Dr. Gregory Fontana, chairman of cardiothoracic surgery at Lenox Hill Hospital in New York City.
This older population is very broad and represents probably the largest proportion of individuals who need this type of treatment, Fontana said, although the results probably can be extrapolated to other groups.
The U.S. National Heart, Lung, and Blood Institute has more on bypass surgery.
