Mayo Clinic researchers have found that cardiac patients who have skin allergies to metals commonly found in jewelry, such as nickel, are at no higher risk for complications if they receive a stent containing these metal components.
The study included 29 patients with a history of skin allergies to stent metal components who subsequently underwent coronary stent implantation. The research team compared clinical outcomes with a matched control group of 250 non- metal allergic patients who received similar stents. In addition to following the study patients' outcomes in the long term, the team reviewed blood to look for signs of allergic reactions.
According to the lead author: "We found no change compared with pre- and post- stent placement in the metal-allergic patients. While we can't be definitive in our advice or counseling, we can suggest that based on our experience, there doesn't appear to be any evidence of both acute and long-term harm."
The study was published in Circulation: Cardiovascular Interventions. The video is below:

I must disagree with this doctor I just left Mayo clinic in Rochester and it was confirmed that the wire containing nickel was in fact causing many internal issues from vomiting, muscle aches, rashes, fatigue, etc...
