Once a myocardial infarction occurs, the timeliness of rescue is very important. There is a rumor that in the event of a myocardial infarction, one can cough vigorously to save one’s life. Is there any basis for this statement? We remind you that misbelieving rumors can be fatal. Here are the self-rescue methods for myocardial infarction to dispel the rumors!

What is myocardial infarction

Myocardial infarction can be called a heart attack. It mainly causes the blood vessels supplying the heart to become narrowed and blocked, which in turn causes heart muscle necrosis, affects heart function, and can be life-threatening in severe cases.

Although myocardial infarction occurs suddenly, there are still traces before the attack, such as chest tightness, chest pain, slight difficulty breathing, cold sweats, or unconsciousness. If you can seek medical treatment immediately, the danger of myocardial infarction can be avoided.

Can one survive a myocardial infarction by coughing?

Myocardial infarction is highly fatal and often catches people off guard. In order to seize the golden life-saving moment, a method of “myocardial infarction can be saved by coughing” has been circulated on the Internet, called “cough CPR”; the guidelines state that once symptoms of myocardial infarction occur, , the patient must cough vigorously to help the heart that is about to stop beating continue to pump blood and avoid death.

In fact, not only does this method have no medical basis, but if you cough too hard, it may have counter-effects and even kill you on the spot. The principle is that myocardial infarction is a blockage of the blood vessels supplying the heart, causing ischemia of the heart muscle. Coughing vigorously will increase the pressure in the chest, right atrium and right ventricle, affecting the expansion of peripheral blood vessels and blood flow to the heart. Therefore, coughing vigorously will increase blood pressure. Decline, even shock, increased risk.

In other words, the so-called “cough CPR” self-rescue method for coughing has no basis. It is usually recommended to pay attention to the signs of myocardial infarction and seek medical diagnosis immediately if any abnormality is found. Doctors can provide appropriate treatment based on the patient’s electrocardiogram changes, symptoms, and their own diseases. treat.
