“Squeezing chest suddenly appeared a large area of pain, this is a very dangerous warning, suggesting that there may be acute cardiovascular events such as acute myocardial infarction there needs to immediately go to the hospital!” Well of Cardiology, Medical Hospitals, deputy director of the Wo-dong Wu stressed that the Chest pain is often a precursor of acute myocardial infarction, but there are many patients clinically this “warning” does not pay sufficient attention to a delay of several hours to the hospital and lost the best treatment time.

The greater the scope the more intense chest pain and myocardial infarction

Myocardial infarction is the most common cardiac emergency, most patients when the disease is the most common symptoms of chest pain. Acute myocardial infarction due to chest pain and general pain, not the same, chest pain concentrated in the upper abdomen, often expressed as squeezing kind of pain, but persistent pain in a large area of the entire piece. Pain, patients are often cold sweats, sudden change in his face. Wu Wo-dong, said the event of such a chest pain, and patients themselves have diabetes, hypertension, family history of coronary heart disease, age above 40 years old, must not be taken lightly, the need immediately to the hospital for treatment.

In general, the extent of chest pain and myocardial infarction scope, location is proportional to the relationship. Larger infarct size, location more chest pain will be more intense. If the patient began to show mild chest pain, then pain can not tolerate even more severe, indicating the scope of more and more extensive myocardial infarction, or infarction of the area increased, more dangerous.

The longer the delay the higher mortality rate

“Chest pain, within two minutes if we can realize that this may be a harbinger of acute cardiovascular events, immediately go to the hospital, we will have to secure the best time for treatment. But in fact we have encountered many patients, chest pain, after its snack drug or rub points, oil, dragged on for two or three hours or even 56 hours before go to the hospital, a number of patients to the hospital has been shock. “Wo-Wu Dong said, myocardial infarction for too long will lead to myocardial necrosis, high mortality rate. Studies have shown that acute myocardial infarction during the 1 minute’s delay, the success rate of CPR will be declined 7% to 10%.

Therefore, Wu Wo-dong proposal, a major area of crushing chest pain and I have a heart attack in patients with risk factors, they should first call 120 emergency call. Before the arrival of the medical staff, patients, oral administration of nitroglycerin tablets or amyl nitrite vasodilators such as quick at the same time you can take a deep breath and then forced coughing, which are effective for self-rescue.
