After nearly 30 years in the clinic and seeing countless patients of all kinds, there are some feelings. Some people come to the hospital soon after they get sick, while others tend to be sick until they are at an advanced stage. The treatment effect is completely different between the early stage and late stage of the disease. The most typical example is tumor. In fact, every systemic disease has to be treated early. The late stage of tumor is chronic failure and has a consuming and painful experience that is easy for the living to bear in mind. Then, early detection of the signs of disease is something that everyone needs to be aware of and is a matter of life comfort. I am a cardiovascular specialist and cannot tell you how to pounce on the information of tumors, but I remind you how to receive the information of cardiovascular diseases. Cardiovascular emergencies, where sudden death can occur, are more dangerous than tumors. Advanced heart disease is just as incurable and painful. If, you have intracardiac discomfort during exertion, in the early morning, in the morning, or after a full meal, that is even very brief, you should pay attention to it; the intracardiac discomfort may also not be serious, not the typical angina pectoris that the book talks about, and it has happened several times, you must seek medical attention. If, for example, you have hypertension, be sure to control your blood pressure while controlling your weight. Sudden dizziness, stomach upset, abdominal pain, and walking leg pain should not be ignored. Famous people such as Mr. Maji, and many patients I met, who usually already had these and those symptoms, did not pay attention to them because of the short period of time, which brought bad results. When heart disease symptoms strike, the condition is serious, but, the short duration is the reason why it is not easy to be alerted. Unlike stroke, there is a lesion immediately limb hemiplegia, immediately seek medical attention. With the development of society, obvious diseases such as: heart murmur, fast heartbeat, etc., are already known to seek medical attention. Often, it is the people who think they are healthy, who work every day, and who have normal annual routine physical examinations, who ignore the above problems. Remind everyone to pay attention to some signals from the body, timely consultation, and keep a good green mountain always.
