Situation 1: Li often drinks and socializes, his weight is high, he was diagnosed with coronary heart disease two years ago, accompanied by diabetes and hypertension, due to untimely medication, heart failure was found before stenting, low heart function, then the stent was implanted under the advice of the doctor, the surgery was relatively successful, the blood supply to the heart muscle was restored, the chest pain symptoms disappeared completely, but due to the impaired heart function, it is not recommended to do physical work, but you can do some Light exercise. Situation 2: Wang is young, usually does not smoke or drink, but due to his work, his diet is unhealthy. He was diagnosed with coronary heart disease at the beginning of last year, the degree of stenosis is not high 80%, but the symptoms are frequent and seriously affect his normal work, so he underwent stent surgery. The ability to do physical work depends on two conditions: 1. myocardial ischemia: the reason why patients with coronary artery disease need stents is because the coronary vessels are blocked, blood cannot flow, the myocardium lacks sufficient blood perfusion, and the heart’s activity is required to consume blood oxygen, when the patient does physical work, the energy to be consumed will increase, once the patient has myocardial ischemia will be unable to meet the consumption and symptoms will occur, and After stenting, the patient restores the blood supply of the blood vessels here, and as long as the other blood vessels are not narrowed and the myocardial ischemia disappears, then there is no difference with normal people at all; on the contrary, if the myocardial ischemia still exists, the patient cannot do physical work. 2, heart failure: as the end stage of the heart, a variety of heart disease patients may appear, once the patient is diagnosed with heart failure, then the situation is more critical, because of coronary heart disease and heart failure patients, even through the stent and medication, so that the myocardial blood supply restored, the symptoms completely disappeared, heart function is still difficult to reverse recovery, if only the first level of heart failure patients, then indeed can do physical work, but As time goes by, the heart function continues to be impaired, not to mention doing physical work, and eventually it may even be a problem to walk. Stenting is an emergency measure to temporarily restore blood circulation, it cannot be used as a condition for any diagnosis or problem, because there may be multiple blockages in the patient’s blood vessels, and stenting cannot be used for everything, so we need to make an individual analysis according to the patient’s condition and body, and it is impossible to give a conclusion casually, otherwise it will not only fail to help the patient, but even endanger the patient’s life and health.
