The price of a simple cardiac angiogram is around 5,000 yuan, and it is currently performed in tertiary hospitals nationwide, and certainly in some secondary hospitals. The cost of the test is basically fixed, because the materials used are relatively fixed, so the cost is basically the same, around 5,000 yuan. Of course, there are differences, for example, in some cases of abnormal coronary artery development or opening, other materials are needed, and the more materials used, the higher the cost, but generally it will not exceed 6,000 yuan. The purpose of the cardiogram is to see the degree of coronary artery stenosis and to determine the next treatment plan. The cost of this test is relatively high, but if coronary artery disease, myocardial ischemia, or atherosclerotic stenosis of the coronary arteries is suspected, it is very necessary to have a coronary angiogram. Only when coronary angiography is done to clarify the condition and severity of the vascular lesion can the next treatment plan be decided.
