No Extra Benefits Are Seen in Stents for Coronary Artery Disease

This review, published in The Archives of Internal Medicine, included only prospective randomized trials that compared P.C.I. and medical therapy with medical therapy alone. There were 7,229 patients in all, half randomized to P.C.I. and half to medicine alone. More than 70 percent of the surgical patients received stents, and the studies followed patients for an average of more than four years.

Death rates were 8.9 percent with P.C.I. and 9.1 percent with medical treatment. Rates for nonfatal heart attacks were 8.9 percent for those who got stents and 8.1 percent for those on medicine alone.
