Cardiac angiography is a commonly used test and treatment for cardiovascular disease, and the typical cost for a simple cardiac angiogram is about$4,000. However, if stenosis or obstruction is found during the cardiac imaging process, further stent implantation procedures need to be considered, and the cost of stent placement can be very high, possibly tens of thousands of dollars for a single stent, and the specific cost of the procedure is related to the quality and quantity of supplies used. The overall cost of continuing the interventional stent procedure treatment after cardiac imaging is usually about 100,000 yuan. However, with the current improvement of medical insurance and rural cooperative medical care, the cost borne by oneself is significantly reduced.
