Drug-eluting stents may be responsible for allergic reactions in some patients
by Mike Adams, the Health Ranger, NaturalNews Editor
Researchers from Northwestern Memorial Hospital claim that drug-eluting stents provoke allergic reactions in some patients, raising serious questions about the future of these stents in medical procedures.
Drug-eluting stents have greatly reduced the risk of repeat blockage of heart arteries, but researchers from Northwestern Memorial Hospital have found that in some patients, the stents can cause allergic reactions that can have serious consequences.
Dr. Bennett developed and directs the Research on Adverse Drug/Device Events And Reports (RADAR) Project, which compiles information from reports submitted to the U.S. Food and Drug Administration's (FDA) database as well as reports by drug companies and independent researchers throughout the world.
Symptoms included rash, difficulty breathing, hives, itching and fevers.
They also concluded that the polymer coating on the stent itself is the most probable cause of hypersensitivity in the majority of cases rather than the medications the stent is coated with.
"It is important to keep the findings in perspective," says Charles J. Davidson, MD, an author on the paper and medical director of the Cardiac Catheterization Lab at the Bluhm Cardiovascular Institute of Northwestern Memorial Hospital and professor of Medicine at Northwestern University's Feinberg School of Medicine.
This study was supported by grants from National Institutes of Health.
