Coronary heart disease stent in general several

Coronary heart disease stent is generally limited to 4.

For coronary artery stenosis degree greater than 70%, unstable angina pectoris, acute myocardial infarction patients need to consider stent implantation, and the number of patients placed stent mainly according to the degree of vascular stenosis, stenosis site decision. In general, the more severe the stenosis, the more the number of stents placed. However, if more than 4 stents are implanted in the blood vessel, it may cause excessive pressure on the vessel wall and cause vessel rupture. Therefore, the number of stents implanted in coronary heart disease is limited to 4.

For patients with severe vascular disease and excessive stenosis, it is recommended to consider cardiac bypass surgery to improve myocardial blood supply.
