Don't take medicine casually if you have a heart attack at home.

For example, nitroglycerin, a drug, has the risk of hypotension when it is eaten under the condition of unclear blood pressure, which is easy to cause shock.

Here's what you should do:

First, make sure you have a heart attack. The symptoms of myocardial infarction are not only chest pain, but also pain in other parts, such as the upper abdomen or back and neck. At the same time, the skin will become pale, breathing difficulties, irritability.

Second, quickly dial 120. The heart attack is so serious that there is no way to get out of danger through self-regulation. Be sure to dial 120 quickly. Be clear about your position. If you are at home, please open the door so that emergency personnel can enter.

Third, calm down. Myocardial infarction can make people feel very anxious and have great emotional ups and downs. Try to calm yourself down at this time, otherwise the condition will be more serious.

Fourth, lie down and rest. Don't have any activities after a sudden myocardial infarction, and don't go to the hospital by yourself. Stay quiet and wait for the door at 120. If you can, please lie flat on the bed and wait. If you can't lie flat, you can wait on the sofa.

Fifth, don't take medicine indiscriminately. Otherwise, unknown problems may appear, which will add trouble to the next rescue work.
