This is a misleading question! It is true that a stent does not cure a disease, but it can save a life! Elderly people are inherently less physically fit than young people, and are very likely to suffer from cardiovascular diseases, and once they reach the point of stenting, then the condition is definitely not light, and it is very likely that the patient’s coronary artery stenosis is higher, the myocardial ischemia is severe, and there are very serious symptoms such as chest pain, chest tightness, panic attacks and palpitations, and it is only then that the doctor will advise the patient to undergo stenting surgery for emergency care, to quickly restore the blood circulation, which will enable the The patient’s symptoms are temporarily relieved or even disappear. However, stenting is not a “miracle drug” that can cure the disease, as we say. The mechanism of stenting is to implant the stent into the narrowed blood vessel, to open the blood vessel through the pressure of the balloon inside the stent, and to restore the blood circulation, but this kind of emergency treatment does not have the effect of targeting at the causes of coronary artery disease, so the patients will still need to take medication for control in the future, to prevent the occurrence of undesirable events. adverse events. The reason this patient is weak is probably heart failure, which has nothing to do with the stent! The description of the problem is very interesting, the description does not say that the most common symptoms worsened, but rather self-reported “weakness”, then we can completely analyze it, if the patient’s symptoms did not improve significantly after stenting, or even worsened, then we can completely determine: in-stent thrombosis, side branch involvement, slow flow, pericarditis, stent reaction, arrhythmia, arrhythmia, stent failure, and so on. reaction, arrhythmia, incomplete revascularization, and other causes. However, this patient said that he was weak, and we often describe weakness in terms of weakness and fatigue, which are typical symptoms of heart failure. Since this patient had underlying diseases that could induce heart failure and were serious and difficult to control, I judged that he had already had heart failure before stenting, and his cardiac function had been in an impaired state, and his coronary artery disease had been covered up. After the stent surgery, the blood transportation system was rebuilt and the symptoms of coronary heart disease disappeared, and the patient would obviously feel the symptoms of heart failure. To summarize, although stent can not cure the disease, but it can temporarily relieve the disease, and there is no direct connection between physical weakness and stent or not.
