Drug-Eluting Stents Safer

ghaliThe Libin Cardiovascular Institute of Alberta’s Dr. William Ghali shares details of a study that concludes drug-coated stents are actually safer than the standard alternative a year after insertion.


The mesh tubes, called drug-eluting stents, which prop open cleared coronary arteries, have sparked worries they can cause lethal blood clots. But a study of some 6,400 Alberta patients found they were significantly safer than their bare-metal counterparts 12 months after angioplasty surgery.

“Overall, the outcomes appear to be slightly better in patients who get drug-eluting stents than patients who get bare-metal stents,” says Dr. William Ghali, the senior study author and University of Calgary professor.

The study found mortality rates related to the 1,120 patients with drug-eluting stents were 3.0 per cent compared to 3.7 among the 5,320 patients who had received the bare-metal variety.
