What are the first aid methods for myocardial infarction

Patients with myocardial infarction are very common in our lives. If some patients are stimulated or frightened in public places, it is possible that the disease will worsen. When myocardial infarction occurs suddenly, first aid methods can actually be used to help patients regulate their bodies.

1. First, calm the patient, do not panic and let him rest in bed immediately, because fear and anxiety can increase myocardial oxygen consumption and expand the area of ​​infarction.

2. At this time, an appropriate amount of sedatives and analgesics, such as diazepam, can be given; at the same time, nitroglycerin, quick-acting heart-saving pills, etc. can be given orally. If there is a small oxygen cylinder or oxygen bag, oxygen can be given; if the pulse disappears, convulsions, etc. occur, immediate rescue should be carried out as if sudden death occurs.

3. The patient must continue to inhale oxygen during the transportation. During the whole process, care should be taken not to let the patient exert any force. For patients living upstairs, a chair can be used for transportation to avoid compressing the chest and affecting the patient's breathing when carrying the patient.

4. Call an ambulance. If an ambulance is not available, a flatbed tricycle will also do. Never ask the patient to walk or take a bus to the hospital, so as to avoid expanding the scope of myocardial infarction or inducing serious complications, causing an accident.

The weather is hot and cold, so it is important to prevent myocardial infarction in winter. Under the influence of severe cold or strong cold air, coronary arteries may spasm and cause secondary thrombosis, leading to acute myocardial infarction. When the climate changes drastically and the air pressure drops, patients with coronary heart disease will feel obvious discomfort. Data show that low temperature, strong winds, and rainy weather are one of the causes of acute myocardial infarction. Therefore, whenever the weather is bad, patients with coronary heart disease should pay attention to keeping warm, or take appropriate coronary artery dilating drugs for protection.
