Cardiac stents, if it is simply the money of stents, currently stents are divided into two categories: one is domestic; one is imported, and many joint ventures. The most expensive individual stent is around 20,000 yuan; the cheapest stent is the domestic one, close to 10,000 yuan a piece. The overall cost of a stent, from the time a patient is hospitalized to the time a stent is placed, is 30,000-40,000 RMB. If you choose the imported one, it may be relatively more expensive and needs more than 40,000 yuan; if you choose the domestic stent, it is relatively cheaper and 30,000 yuan is enough. For each additional stent, you have to add 10-20,000 yuan, and the amount of money added is close to 20,000 yuan. So for heart stents, the cost of a single stent is usually 30-40,000 RMB, and each additional stent adds 10-20,000 RMB, which is the approximate cost. Each person has a different vascular lesion and the devices used are not exactly the same, so there is a difference in cost, but the difference in one stent will not be$20,000.
