Considering coronary stents? Here are the facts you must know!

1. What are coronary stents and how they work in your body? 

Coronary stent is a metal tube. When the stent is placed, the blood vessel needs to be compressed by a balloon to squeeze the cholesterol and necrotic cells accumulated in the blood vessel onto the blood vessel wall and sandwich it between the stent and the vascular intima, so as to play a role in stretching blood vessels and dredging blood flow.

In other words, the coronary artery stent only squeezes the plaque and squeezes it apart, but does not remove it, and solves the problem of arteriosclerosis from the root cause. Therefore, it is also called "palliative therapy" in medicine, which is a remedy for emergencies.

2. Do I need to implant coronary stents? 

Some people say that if the cardiovascular stenosis exceeds 75%, a coronary stent is needed, and if it does not exceed 75%, no stent is needed. In fact, it is not necessarily because the degree of vascular stenosis is not used as a criterion for stent placement.

Generally speaking, if there are no symptoms of myocardial ischemia and the plaque is stable, it may not be necessary to install a coronary stent even if the blood vessel is 90% narrowed; and if the myocardium supplied by the blood vessel is large and there is obvious myocardial ischemia, the plaque is not stable, which may rupture at any time and cause thrombosis. In this case, even if the vascular stenosis does not exceed 70%, stent surgery must be considered.

Simply put, people who may have a myocardial infarction at any time should consider installing a coronary stent. Of course, people who have already had a myocardial infarction should receive stent treatment in time under the advice of a doctor.
