Can a heart stent fall out? There is a risk of stent dislodgement during the insertion process, mainly due to the bending and severe calcification of blood vessels. After the stent is successfully inserted into the body, it will not fall out again, even after participating in activities, or performing external cardiac compressions or defibrillation with electric shock. Will there be any rejection after the heart stent is inserted into the body? No significant rejection between the stent and the body has been found. How long will a cardiac stent stay in my body? After the stent has been successfully inserted into your body, the surface of the stent will be completely covered by a new lining in about 4 weeks and will be fully integrated into your blood vessel, acting as part of your vessel wall and providing support. Thus, the stents will remain with you for the rest of your life. After implantation, they will not move around in your body. Will I feel the presence of the heart stent inside my body? No. Once the stent is placed in the artery, you will not feel the stent. Will an MRI have any effect after a heart stent is placed? MRIs should not be performed for at least eight weeks after the placement of a stainless steel stent. The newer cobalt-chromium alloy stents do not have this restriction, so please consult your doctor. Are there any restrictions or precautions? If you have a stent in place, it will not affect your ability to do any activities, but you should consult your doctor before engaging in strenuous activities. When you are being treated by another doctor, especially if you need surgery in the near future, you need to tell your doctor that you have a stent. When can I start my daily life again? It is important to follow your doctor’s advice. You will usually return to work and continue your normal daily routine one week after your stent surgery. Will my stent cause the metal detector to alert me when I am going through security at the airport? No. Will my symptoms recur? Yes, you may experience those symptoms again, either because of a new blockage in the area that was treated or elsewhere in the artery. A coronary angiogram should be repeated about six months after surgery, with or without symptoms, for early detection and timely management of the stenosis. How can I prevent a recurrence of symptoms? There is no sure way to prevent recurrence of symptoms, but you can reduce the risk of recurrence by staying on medication, exercising, quitting smoking, and eating a healthy diet. Follow the advice your doctor gives you about making lifestyle changes.
