It is incorrect to say that stents are not recommended. Stents can be life-saving at times, and therefore need to be placed when the condition warrants it. Stents are usually used in cardiovascular and cerebrovascular diseases, such as acute cerebral infarction or acute myocardial infarction, due to the blockage of thrombus can lead to the narrowing of the blood vessels, at this time, the brain or the heart will have insufficient blood supply, which will lead to ischemia, hypoxia and even necrosis, which is a serious threat to the patient’s life, and then timely restoration of blood vessel smoothness is the most effective treatment measures. By implanting a stent into the blocked blood vessel, blood flow can be effectively restored, thus restoring the blood supply and oxygenation of the heart or brain, which can not only save the patient’s life, but also effectively improve the patient’s quality of life in the future. Currently, stent implantation technology has become extremely mature, so patients with indications should actively cooperate with the treatment and should not believe in rumors.
