Being able to go near a magnet after having a heart stent. Cardiac stents are mainly made of alloys, and the stent will not be displaced when the patient is in the MRI 1.5T or 3.0T field strength environment after stenting. Due to the washout of coronary blood flow, localized heat production will dissipate quickly and will not result in a localized temperature increase. In particular, cardiac stents used in the last five years can also be used for high-field magnetic resonance examinations, but in the case of stents implanted many years ago, a comprehensive judgment should be made based on the type of alloy and type of implanted stent. MRI is prohibited for a short period of time after coronary stent implantation, but if it has been more than three months since the procedure and the patient is stable, MRI can be considered if necessary. In addition, having had cardiac stent surgery, but because the material of the cardiac stent is not ferromagnetic, magnetic therapy and MRI can usually be done. It is important to maintain a good state of mind after heart stent surgery because heart disease should not have symptoms of anger, as anger can lead to more serious consequences of heart disease. At the same time, it is necessary to develop good living habits, go to bed on time and keep enough sleep. It is recommended to improve the corresponding examination and treatment under the guidance of physician.
