Cardiac neurosis is a special type of neurosis, with malfunction of the cardiovascular system as the main manifestation and other manifestations of neurosis. Cardiac neurosis occurs mostly in young adults, most often between the ages of 20 and 40, and most often in women, especially menopausal women. There is no pathological evidence of organic heart disease. The patient’s complaints are numerous and scattered, lacking an intrinsic connection, and the symptoms are variable without evidence of disease on objective examination. Onset is often triggered by anxiety, emotional stress, trauma, or overexertion. The symptoms of cardiac neurosis are varied, with typical symptoms much like those of an acute heart attack, including chest tightness, panic, breathlessness, tightness in the precordial region, and even a sense of pain and near death in some patients. The patient’s cardiovascular system symptoms are characterized by a wide variety of symptoms, sometimes mild and sometimes severe but mostly not severe. Patients generally do not have evidence of organic heart disease, but it may coexist with or occur in addition to the latter. It may also be accompanied by symptoms of autonomic dysfunction, such as excessive sweating, cold hands and feet, tremors in both hands, frequent urination, increased frequency of stools or constipation. In addition to cardiac symptoms, patients may also experience other symptoms such as dyspnea, dizziness, insomnia, and excessive dreaming. Cardiac neurosis is difficult to diagnose based on symptoms, and organic diseases must be ruled out before a diagnosis can be made.
