Research suggests metal allergy does not affect outcomes following stent implantation

摘要

Stent implantation into patients with a history of metal allergy has raised concerns in the past, however a team from the Mayo Clinic (MN, USA) has recently published research from a single-center study that suggests metal allergy has no impact on outcomes following stent implantation.The team compared 29 allergic patients with coronary stent implantation with 250 nonallergic patients. Of the allergic patients, 26 were hypersensitive to nickel and nine to chromium. The group found statistical similarity between the allergic and control groups for all outcomes studied, which included in-hospital death, 30-day death, 4-year death andtarget lesion revascularization. No change was observed in counts of circulating eosinophils and lymphocytes after stenting in the allergic group.
