Cardiac neurosis is a special type of neurosis, with malfunction of the cardiovascular system as the main manifestation, which can be combined with other manifestations of neurosis. The symptoms are diverse and include palpitations, precordial pain, chest tightness, shortness of breath, dyspnea, dizziness, insomnia, and excessive dreaming. It mostly occurs in young adults, with the most people aged 20 to 40 years old, and is mostly seen in women, especially menopausal women. 1. Causes Due to anxiety, tension, emotional excitement, trauma and other factors, the central excitation and inhibition processes are impaired, and the cardiovascular system regulated by the vegetative nerves is also disrupted, causing a series of symptoms of sympathetic hypertension. In addition, overexertion, physical activity is too little, the circulatory system lacks appropriate exercise, so that the slightest activity or a little exertion can not adapt, thus producing excessive cardiovascular response to the disease. The symptoms of cardiovascular system are varied, sometimes mild and sometimes severe, but not serious, usually without evidence of organic heart disease, but can coexist with or occur on the basis of organic heart disease. The medical history should ask in detail whether there are any triggers such as anxiety, emotional excitement, trauma or overexertion, whether the patient has ever been diagnosed with “heart disease”, the correlation between the feeling of panic, shortness of breath or precordial discomfort and activity, exertion and mood, and how the sleep condition is. 3.Examinations ECG often shows sinus tachycardia, some patients have ST-segment depression or horizontal downward shift, T-wave depression, biphasic or inversion, mostly in leads II, III, aVF or V4-6, and often changes, and the heart test is positive. Some patients have a positive exercise test, but the ST segment and T waves return to normal when the “Takayasu exercise test” is performed. Ultrasound examination of the heart can exclude structural abnormalities of the heart, large vessels and valves. 4, diagnosis 1, medical history, symptoms based on clinical manifestations, previous cardiac examination results, medication history and efficacy can help the diagnosis. 2, physical examination findings, physical examination is often no special findings. Mostly anxious state or nervous expression, blood pressure may be normal or mildly elevated. On cardiac auscultation, there may be increased heart rate and increased heart sounds, which may be accompanied by soft systolic murmurs of grade I-II in the precordial region and occasional premature beats. 5. Differential diagnosis The diagnosis of cardiac neurosis should be made on the basis of exclusion of organic cardiac pathology, and caution should be exercised in the diagnosis. Endocrine diseases such as hyperthyroidism, pheochromocytoma and organic heart disease such as coronary artery disease, cardiomyopathy or viral myocarditis should be excluded. The chest discomfort in patients with coronary artery disease is often related to activity or physical labor, with negative heartburn test and positive exercise test; patients with cardiomyopathy have positive cardiac ultrasound findings; patients with viral myocarditis mostly have a history of upper sensory disease, and elevated serum myocardial enzymes in the acute phase can be used for differentiation. 6, treatment 1, psychotherapy (1) to make the patient understand the nature of the disease to relieve their concerns, so that they believe that there is no organic cardiovascular disease; (2) health care workers must be patient with the patient to gain his trust and cooperation; (3) to avoid various factors that cause aggravation; (4) to encourage patients to physical exercise; (5) to encourage patients to self-adjustment of mind, arrange the work and rest time, the appropriate amount of recreation (5) Encourage patients to adjust their mindset, arrange their work and rest time, and engage in recreational activities and travel. (2) Give symptomatic treatment with drugs 7. Prognosis Most of the cardiac neurosis is not organic heart disease, as long as active treatment can generally recover, the prognosis is good, but the long-term symptoms of serious patients can significantly affect normal life and work.
