Many patients often ask their physicians, “Am I seriously ill?” It would be easy to simply answer questions like these. For example, hypertension grade 3 is more serious than grade 2, and coronary angiography confirms that very severe stenosis of the coronary artery is more serious than mild stenosis. But this answer is incomplete. Because the seriousness of the disease itself is not only determined by artificial staging or pathological changes, there is also a very important issue is related to people’s attitude toward the disease and prevention, treatment is timely and correct. This is a fact that has been proved in real life and clinical practice. For patients with the same condition, those who are treated positively and correctly are much better than those who are treated negatively. At present, due to various reasons, some advanced treatment means are not recognized by patients, and therefore can not get timely and effective treatment, which is also very regrettable. Early hypertension, for example, can lead to serious cardiovascular pathology if not treated aggressively. But even in patients whose blood pressure continues to increase significantly, as long as the blood pressure is reasonably and correctly controlled below a reasonable standard, generally not to the occurrence of hypertensive emergencies. From this, we can see that those so-called “healthy” people once the onset of the disease, some of the disease is deterioration of the advanced stage, in fact, the reason is also here. Visible, for the degree of judgment, not only to see what disease, lesions to what extent, but also to see their own attitude toward the disease; see what kind of medical conditions you can receive; see your future treatment, prevention, and physicians to cooperate with the degree of effort to determine your prognosis — that is, the so-called severity of the disease problem. It has been said for a long time that “a doctor treats the disease before it occurs, while a Chinese doctor treats the disease that has already occurred” and that “one point of prevention is better than twelve points of treatment”. These words are still philosophical today.
