I’m wondering if it’s ok to use an induction hob for someone with a stent? Does anyone know. (No pacemaker or ICD).
Can I use an induction hob if I have ... - British Heart Fou...

Never had a problem with mine.
Good to know
Stents are usually stainless steel and not magnetic. So there shouldn;t be a problem.....
Your question reminded me of a bloke who broke his arm. "Will I be able to play the piano?" he asks.
"In about six weeks" is the reply.
"That's amazing. I've been trying for the past ten years, and still couldn't".
I can understand why you have asked the question and would love to know the answer, if you ever get one...
To explain my concern: This is speculation on my part; I'd love to see the explanation from someone who does know the answer and can cite a proper scientific (and refereed) paper. An induction hob uses an alternating electromagnetic field to generate heat in the pan which then transfers the heat to the food to be cooked.
Yes stents are usually non-magnetic, but they are conductors and will act like a small radio aerial- thus it will pick up the alternating electric field (Just like a radio aerial) and energy will be transferred to the stent. (The amount of energy will depend on the frequency of the AC field used by the hob and the length of the stent).
That energy, may well be small but it must go somewhere and it can really only be converted into heat as far as I can see. It doesn't have to heat up much before it starts heating up the wall of your artery - I suspect that over time, this might not be too good for your artery in the region of the stent. - a long, slow cook. An expert might also usefully consider what the effect would be if the stent is a resonant length and couples in properly to the AC field from other radiative devices (see next para).
I must say again, THIS IS SPECULATION ON MY PART, IT IS NOT AN ANSWER TO THE QUESTION. The question could usefully be posed in a more generic way and ask about all RF fields eg RF from mobile phones, wifi systems and smart meters to mention just a few of the emitters we almost all will come into contact with on a daily basis.
I found this (at cda.eu/hobs/how-does-induct... ) which doesn't really answer your question but may help those with pacemakers.
"Due to the strong electromagnetic field created by an induction hob this type of hob could affect your pacemaker if you have one fitted. According to The British Heart Foundation (BHF) pacemaker wearers should keep a distance of at least 60cm or 2ft from the appliance as it may interfere with your settings. The BHF have said that an induction hob would not cause significant damage to your device, but due to there being many different types of pacemakers, each could be affected in a different way."
But Wikipedia included this in its explanation: ( en.wikipedia.org/wiki/Induc... )
"For nearly all models of induction cooktops, a cooking vessel must be made of, or contain, a ferrous metal such as cast iron or some stainless steels. The iron in the pot concentrates the current to produce heat in the metal. If the metal is too thin, or does not provide enough resistance to current flow, heating will not be effective. Most induction tops will not heat copper or aluminum vessels because the magnetic field cannot produce a concentrated current; "all metal" induction tops use much higher frequencies to overcome that effect. "
The last sentence though, does give me concern as it seems there is a type of hob that will cause coupling, and therefore heating, in a wider range of metals
Also from forums.egullet.org/topic/15...
"The Panasonic KY-MK3500 is a 208/220v single phase hotplate that should operate on any home circuit that is wired for coil or radiant ranges. It is rated to 3500 Watts at the "old" 24kHz frequency (ferromagnetic pans), and 2500 Watts at the 90kHz frequency chosen for aluminum and copper, and switches automatically between the two."
So, does anyone have a definitive answer please??
sorry about the length
Sorry but a stent isn’t a pacemaker is is simply a stainless steel mesh tube which over time becomes intertwined with the artery wall ( please understand I am not an expert but asked questions after my two stents) so I would ask a cardiac consultant or professor of cardiology.
I found another discussion about this and because it’s non magnetic there wouldn’t be any issues.
I learned this week (assuming that it’s true) that stents and my replacement knee are magnetic, but at a very very low level.
They aren’t damaged by the MRI, but may distort the image a bit (which can be compensated for- and that might be the knee, which is a bit bigger than the stent......)
An induction hob has to actually be in contact with the ferrous metal pot to conduct the heat to cook the food. A stent within the artery will not be in direct contact so I can’t see any problems at all.
You are probably better off using central heating.
Hi , my Colin has a stent and he uses our no problem
