As a disease that poses a great threat to our lives, coronary heart disease is a disease that everyone fears. The patients I have met are very frightened and worried after being diagnosed with coronary heart disease. Generally speaking, coronary heart disease is most common in the middle-aged and elderly groups, but nowadays there are quite a number of young people with coronary heart disease. “If you are sick, you need to treat it early”, and coronary heart disease is also a disease that can easily pose a direct threat to the patient’s life if it is not detected in time or treated properly. In fact, if the symptoms of coronary heart disease can be detected at an early stage it can be treated early and achieve good therapeutic results. Many people simply think that the symptoms of coronary heart disease is nothing more than chest tightness and shortness of breath accompanied by chest pain. In fact, there are many symptoms that are easily manifested in patients with coronary heart disease. Some symptoms may not be closely related to coronary heart disease on the surface, leading some patients to ignore the condition and delay treatment. So, many patients have to ask, what exactly are the symptoms of coronary heart disease? When the coronary heart disease is aggravated, the patient’s angina lasts longer and the attacks are more frequent, which is the main signal. This is easier for patients to notice. However, a large proportion of patients and their families do not know that patients with coronary heart disease may also exhibit malignant vomiting before the onset of the disease. At the same time, the whole body also feels weak, and even accompanied by incontinence. Last week, I saw a patient with a similar condition, and the first reaction of the patient and his family was not related to coronary heart disease, thinking that it was some kind of gastrointestinal problem. In addition, some patients may experience sweating, and they may feel particularly uncomfortable and pale, and they may become irritable because they are holding their breath. As a matter of fact, if patients with coronary heart disease experience similar symptoms as those mentioned above, it is best to go to the hospital in time for consultation, and at the same time, they also need to take some common medicines for coronary heart disease like quick-acting heart-saving pills. Of course, if the patient suffers from severe chest pain or even sudden cardiac arrest, the family members must be calm and then take active and effective first aid measures, and must not take the wrong first aid method due to panic, so as not to accelerate the patient’s death. In case of an acute attack of coronary heart disease, we should learn the necessary first aid measures at the same time to the emergency center: 1, quiet: should be lying down on the spot, any movement will increase the burden on the heart, endangering life. 2, analgesic: sublingual nitroglycerin tablets, or isopentyl nitrite 1. 3.Oxygen intake: Oxygen should be inhaled immediately when available. 4.Resuscitation: mouth-to-mouth suction and chest compressions. 5, call for help: contact with the hospital, first aid station, ask the doctor to come quickly to rescue or send to the hospital for rescue. Sounds a little complicated, but for the family of patients with coronary heart disease at home, is a must learn. And CPR can’t be stopped at will, it must be continued until the ambulance arrives. Coronary heart disease is very scary, we should not underestimate the harm that coronary heart disease brings to the patient’s body, understand the symptoms of this disease for everyone to do a good job of daily prevention is very beneficial. I often advise my patients, it is best to be able to develop good habits, because this is the best way to prevent coronary heart disease.
