The occurrence of myocardial infarction causes great harm to patients, with rapid onset, serious illness and more complications, especially arrhythmias, cardiogenic shock and heart failure, so the mortality rate is high, plus the high cost of hospitalization, which makes such patients suffer more psychological pressure. Timely and proper psychological care of patients with myocardial infarction plays a very important role in the treatment and rehabilitation of patients. One: change the bad lifestyle, advise patients to quit smoking and alcohol. Because drinking alcohol can trigger or aggravate angina and myocardial infarction; smoking can cause intimal damage, accelerate atherosclerosis and aggravate the condition. Second: it is strictly forbidden for health care workers and family members to discuss issues related to their condition in front of the patient, and it is strictly forbidden to speak stimulating language in front of the patient, and not to tell the patient anything that is too happy or too sad. Third: Patients entering the care unit have nervousness and fear. The environment in the care unit and the conditions that occur in the use of various machines (such as machine noise and skin scratching after the use of electric plates) should be introduced to patients in detail so that they can adapt to the environment, stabilize their emotions and cooperate with treatment as soon as possible. Fourth: For patients who are blindly confident and overly optimistic, they should be repeatedly explained the general knowledge of the disease and advised to arrange their lives reasonably under the guidance of medical personnel; for patients with anxiety, relaxation therapy can be adopted, such as learning qigong, so that patients can comfortably apply relaxation therapy to cope with their inner anxiety and the stimulation of the external environment. Fifth: establish a good and comfortable recuperation environment, quiet and tidy ward; medical staff should be kind and generous in language, so as to make patients feel comfortable. Sixth: explain the evolution of the disease to the patient objectively, explain the need for moderate activity after stabilization, so that the patient understands that inactivity is not only detrimental to the recovery of cardiac function, but can even cause complications such as venous thrombosis. Encourage patients to be active and give guidance on the way and amount of activity; medical staff should closely observe changes in the patient’s condition when the patient is active, so that the patient can feel safe and gradually build up confidence in overcoming the disease. For many family members of patients with acute myocardial infarction, they tend to pay more attention to the patient’s condition and pay very little attention to the patient’s psychological changes. As a reminder, if the patient has a serious psychological disorder, then it will largely affect the treatment effect, so I also hope that you pay attention to it.
