A cardiac coronary angiogram is about$4,000. In general, the indications for performing a coronary angiogram are to consider that the patient has clear symptoms of angina pectoris, and the chances of needing a stent implantation are relatively high, before performing a coronary angiogram. If coronary artery disease is excluded from the examination, coronary artery CTA can be performed. If coronary artery stenosis is found during coronary angiography, and the degree of stenosis is more than 75%, it is recommended to implant a stent. Generally, the cost of implanting a domestic stent, including the cost of the operation, is about 40,000 RMB, and the cost of adding one more stent is only about 8,000 RMB. In other words, the total cost of implanting 2 stents would be around$48,000. If the coronary angiogram suggests a 3-branch lesion, it is recommended to treat it with an operation bypass surgery, which will cost around$100,000.
