Regular detection of blood lipid is the prerequisite for the prevention of myocardial infarction. Low-density lipoprotein cholesterol (LDL-C), commonly known as "bad cholesterol", is closely related to the myocardial infarction. The elevated level of "bad cholesterol" may lead to atherosclerosis, vascular stenosis, and then induce cardiovascular and cerebrovascular diseases such as coronary heart disease and stroke, etc.. It is more dangerous that, the unstable plaque rupture or thrombosis may block the blood vessels within a short period of time, leading to myocardial infarction and life-threatening. To prevent the myocardial infarction, you should start from detection of your blood lipids by knowing the values of “bad cholesterol”. 
To control over "bad cholesterol" is the core for prevention of myocardial infarction. Different groups of populations have different indexes of “bad cholesterol". The patients with dramatic increased "bad cholesterol" (> 4.9mmol / L), diabetic patients over 40 years of age and patients of hypertension combined with a multiple risk factors belong to the high-risk groups, and their levels of “bad cholesterol” should be controlled below 2.6mmol/L. For those patients clearly diagnosed with coronary heart disease, the level of “bad cholesterol” should be controlled below 1.8 mmol/L. In addition, the lower the “bad cholesterol" level, the better the effect of preventing myocardial infarction. 
Once myocardial infarction occurs suddenly, you should call 120 as quickly as possible. Do not move freely when myocardial infarction occurs suddenly. Open the doors and windows, release the shirt, if the patient has lost consciousness at this time, you should perform cardiopulmonary resuscitation (external chest compression + artificial respiration) immediately. Keep the phones and life-saving channels unblocked during the period.
