Patients with coronary artery disease who need to have a stent implanted, the approximate cost of implanting a stent is around$30,000, and if another stent is added, the cost may increase by about$10,000. The cost of placing a stent for coronary artery disease is more complicated, like a simple domestic stent, the approximate cost is about 7,000 yuan, but it is necessary to calculate the cost of guide wire, catheter, balloon, and arterial sheath and surgery, so it adds up to the above mentioned cost. If the condition is complicated, the cost should be calculated separately. If it is necessary to perform reverse opening of the vessel, if it is necessary to open the vessel by elective rotary grinding technique, if it is necessary to perform intravascular ultrasound, and if it is necessary to perform FFR, the cost should be calculated separately. In some cases, if multiple stents need to be placed and many of the above-mentioned devices are used, the cost may reach about RMB 80,000 for some people. So for stenting in coronary artery disease, it is important to make a basic reference, and the cost is lower for simple conditions.
