Calm response to sudden myocardial infarction

Acute myocardial infarction is due to coronary atherosclerosis, thrombosis or coronary artery spasm, resulting in coronary artery or branch occlusion, resulting in myocardial necrosis due to persistent ischemia and hypoxia.

This disease is more common in the elderly, is a sudden and dangerous emergency, but before the onset of a variety of symptoms. Such as conscious precordial distension discomfort, dull pain, dull pain sometimes to the arm or neck radiation, accompanied by nausea, vomiting, shortness of breath and cold sweat. At this time, we should immediately stop physical activity, calm down the excited mood to reduce myocardial oxygen consumption, and oral nitroglycerin tablets or isoamyl nitrite and other quick acting vasodilators, some patients can avoid the occurrence of myocardial infarction.

When acute myocardial infarction occurs, patients feel severe and persistent pain in the infrasternal or precordial area. Some patients do not feel severe chest pain, or show sudden severe upper abdominal pain due to inferior myocardial ischemia, but other symptoms will be more serious. Rest and taking quick vasodilators can not relieve the pain. If there is no rescuer nearby, the patient should call for help immediately and dial 120 emergency call or nearby hospital call.

Before the rescue, you can take a deep breath and cough hard. The chest pressure and vibration produced by it are the same as the effect of external cardiac compression in cardiopulmonary resuscitation. At this time, coughing hard can win time for follow-up treatment, which is an effective self-help method.

Medical statistics show that the first few hours of myocardial infarction is the most dangerous period, about 2 / 3 of the patients died before medical treatment. At this time, moving the patient, carrying or helping the patient to walk to the hospital will increase the burden of the heart, expand the scope of myocardial infarction, and even lead to the death of the patient.

Therefore, it is very important for the patient to keep calm during first aid. Family members or rescuers should not panic. They should rescue the patient on the spot, let the patient lie down slowly and have a rest, try to reduce unnecessary body position changes, and immediately give 10mg diazepam orally. At the same time, call an ambulance or a doctor for rescue.

During the waiting period, if the patient's face is pale, hands and feet are wet and cold, and the heart beats faster, it indicates that shock has occurred. At this time, the patient can lie on his back with his feet slightly raised and the pillow removed to improve the cerebral ischemia. If the patient is in a coma and his heart stops beating suddenly, his family should not lift him up and shake him, but should immediately use the first aid measure of boxing the anterior area of the heart to make him jump again.

If it is invalid, immediately carry out chest cardiac compression and mouth-to-mouth artificial respiration until the doctor arrives.
