There are often a lot of patients who think that a bad mood (emotion) and the resulting chest disorder is a heart disease or a coronary heart disease, but in fact, mood (emotion) and heart are not the same thing at all. This misunderstanding is related to the fact that both of them have the word “heart” in our language, but in fact they have very different meanings; on the other hand, it is also related to the concept of “heart” in Chinese medicine, which is actually closer to the concept of “heart” in traditional medicine. The concept of “heart” in traditional medicine is closer to mood and emotion, and not all the meaning of “heart”. The heart is an anatomical and functional organ, responsible for pumping blood from all over the body back to the whole body, maintaining blood circulation and blood supply in the body. Mood (emotion) is a mental activity that is governed by the brain and has nothing to do with the heart. Bad mood or malignant emotional stimulation can lead to chest discomfort such as chest tightness, palpitations, chest pain, but such symptoms are not related to the heart, which can be completely normal; on the other hand, heart and other diseases can also lead to changes in the patient’s mood (emotion). Chest discomfort caused by mental (mood) can be called cardiac neurosis, which is more common in women than men, and is often accompanied by social and family triggers, such as neighborhood discord, family misfortune, unhappy work, etc., often accompanied by sleep disorders. Chest discomfort caused by mental (emotional) discomfort often presents a continuous feeling of chest suffocation, related to emotional changes or adverse emotional stimuli, and palpitations can occur after activity, but there is no obvious chest pain, and often the patient feels physically and mentally exhausted, and the chest discomfort cannot be completely relieved after rest, and taking coronary artery-dilating drugs may also be effective, but it takes more than 10-30 minutes to relieve, and the relief of symptoms is not complete. Sometimes the chest symptoms are instead relieved after activity, and the symptoms reappear at rest. Sometimes there is chest pain, but this chest pain is usually in the form of constant dullness or sharp stabbing pain, which can be located in the whole anterior chest or the whole back of the chest, or can be fingertip or pinpoint size. Sometimes there is pressure pain in the rib cartilage of the chest, in the intercostal space, or in the back, which may be a sign of costochondritis, intercostal neuralgia, or myofasciitis of the back. It is because mood and heart are two different things, so the treatment of chest discomfort caused by mental factors with drugs for heart disease is certainly not effective; if it is effective, it is also due to the placebo effect or suggestive effect of the drug, the patient thinks that the drug is effective, others say that the drug is good, the drug on TV commercials, and even the drug with a good name may make the patient feel effective. In this case, as a patient, it is better to see a psychiatrist to eliminate the causative factors as much as possible; as a doctor, you should first explain the truth to the patient, do the necessary tests to exclude the possibility of the disease and relieve his or her doubts about heart disease; do not throw the patient’s favor and use drugs indiscriminately, which will only make the psychological problem more and more serious, not only affecting the patient’s normal life, work and physical and mental health, but also bringing misfortune to the family This will not only affect the patient’s normal life, work and physical and mental health, but also bring misfortune to the family and burden to the society. Do not take the psychological treatment of cardiac neurosis lightly.
