The typical symptom of myocardial infarction should be a pain in the middle and left side of the chest that seems to be suppressed by heavy objects. At the same time, the patient will feel difficulty breathing, his heart will beat faster and he will have a fear of death. However, some patients with myocardial infarction, because the infarction site is close to the apex, and the apex is close to the upper part of the stomach, often patients themselves can't tell whether it is stomach pain. Going to the hospital and saying that you have a stomachache will mislead the doctor's treatment direction. I think that's the case with your uncle.

Myocardial infarction is the death cause of many middle-aged and elderly people, which is much higher than the cancer mortality rate. Because I don't know when or where it will happen. Generally speaking, the blood vessels that supply blood to the heart are blocked, and the myocardial necrosis is because there is no blood supply, and the necrotic part of the myocardium does not work. The heart is an organ that transports blood to the whole body. If a large area of necrosis, the heart can not pump blood to the whole body, other organs will die of ischemia and hypoxia. Brain hypoxia for 5 minutes will cause irreversible brain death, so myocardial infarction is a very urgent disease.

The development of myocardial infarction varies according to the size of infarct area. If it is a small vessel infarction, the patient has a greater chance of survival. If it is a large vascular infarction, the patient is likely to die. In addition, when the patient is ill, many family members are in a panic and busy. They don't know whether to let the patient lie still and rest, so they should give the patient oxygen quickly and then dial 120, so they can't move the patient without permission, which delays the treatment opportunity of patients with myocardial infarction in the early stage.

In addition, I would like to remind you that the attack of myocardial infarction sometimes manifests as toothache and numbness of the left limb. Not every patient will feel heartache.
