Silent myocardial infarction, only a few lack discomfort symptoms; More often, the symptoms are mild or atypical and cannot be found in time. This kind of myocardial infarction accounts for 20% ~ 30% of myocardial infarction cases. A paper was published in Journal of American Medical Association 20 15. The researchers followed more than 2000 participants who had no cardiovascular disease. After 10 years, after magnetic resonance imaging, 8% of them have myocardial infarction scars, and 80% of them claim that they have never had symptoms related to myocardial infarction. The conclusion of this study suggests that the actual asymptomatic myocardial infarction far exceeds people's cognition and imagination.
Silent myocardial infarction, although the symptoms are mild, but the degree of harm is not reduced. Irreversible myocardial necrosis will affect myocardial contractility and lead to heart failure. Moreover, after myocardial necrosis, scar tissue is formed, which may bury the hidden danger of arrhythmia, which may lead to ventricular tachycardia or ventricular fibrillation and bring life-threatening problems. After myocardial infarction, only timely revascularization can save the ischemic myocardium from necrosis. Therefore, high-risk groups need to learn to identify. Usually, there is a body signal of 12, which indicates the occurrence of myocardial infarction.
1 signal of myocardial infarction may be anxiety, feeling doomsday, or fear of death. Some patients will have strong irritability or mood swings a few days before the onset of myocardial infarction.
The second sign of myocardial infarction is chest discomfort. A common feeling is a heavy feeling or fullness in the chest. Some people describe chest pressure 1 boulder, especially female patients. The pain behind the sternum may not be obvious, but they just feel chest discomfort or burning sensation.
The third signal of myocardial infarction is chest pain. The pain of many patients with myocardial infarction will start from the chest and then spread to the shoulders, arms, elbows, back, neck, jaw and abdomen. But some patients with myocardial infarction have no chest pain, only pain in other parts. For example, men have pain in their left arm, or women have pain in their arms, or shoulder blades.
The fourth signal of myocardial infarction is an accelerated or irregular pulse, especially when accompanied by weakness, dizziness, shortness of breath and other symptoms. You need to be vigilant, seek medical advice in time, and do echocardiography and other examinations.
The fifth signal of myocardial infarction is cough, which is manifested as persistent cough or wheezing, and may also cough up blood and phlegm. These are all manifestations of heart failure.
The sixth signal of myocardial infarction is dizziness, even loss of consciousness, which may be accompanied by severe arrhythmia.
The seventh signal of myocardial infarction is fatigue, which is more prominent in women, and fatigue will appear a few days or weeks before the onset of myocardial infarction.
The eighth signal of myocardial infarction is loss of appetite, which may be accompanied by nausea and bloating.
The ninth signal of myocardial infarction is shortness of breath, usually accompanied by chest discomfort. In severe cases, you will find it difficult to breathe.
The 10 signal of myocardial infarction is sweating, and the typical performance is sweating all over the body.
The 1 1 signal of myocardial infarction is edema, which appears in feet, ankles, lower limbs or abdomen.
The 12 signal of myocardial infarction is powerlessness. Some people will feel extremely weak before myocardial infarction, and they have no strength to raise their hands and cast their feet.
Myocardial infarction, even asymptomatic myocardial infarction, usually has aura and inducement. Sometimes angina pectoris attacks frequently and lasts for a long time, and the relief effect of nitroglycerin becomes worse. So the key to saving myocardium is to prevent consciousness. When the body shows signs of myocardial infarction, it is necessary to seek medical attention in time. After all, the consequences of myocardial infarction are very serious. As described in the classic coffin of our traditional medicine, it really hurts, and the hands and feet are clear to the joints, and the heartache is very serious.
