Myocardial infarction 90%, is already stenosis is very serious, at any time there may be myocardial ischemia, if there is no other can cause the risk of the situation, generally recommended to do coronary stenting.
Myocardial infarction 90%, generally refers to a certain one or more coronary artery vessels have 90% stenosis, this situation is still more serious, if you do not do cardiac stenting, in the case of agitation or cold and other stimuli is very likely to induce difficult to relieve the symptoms of myocardial ischemia, such as persistent chest tightness, chest pain and so on. Even some patients can have an attack in a resting state, which can be life-threatening.
For 90% of myocardial infarctions, the installation of a cardiac stent is currently the best treatment. The installation of a stent can restore blood and oxygen supply to the heart muscle and improve the symptoms of heart discomfort. For those who are unable to undergo stenting, treatment options such as coronary artery bypass grafting are available.
Cardiac stenting is now more sophisticated than before, and does not require open heart treatment. For specific treatments, patients can consult their doctors in detail, who will take into account the patient’s personal situation and formulate a reasonable plan.
