The prevention of myocardial infarction

　With angina pectoris or the risk factors of coronary heart disease, should make every effort to prevent the occurrence of myocardial infarction, in their daily lives, we should pay attention to the following points:
1. Do not carry too heavy to move goods. Lifting weights will inevitably move when bending breath, respiratory, circulatory system and the impact of similar force breath stool, elderly patients with coronary artery disease is a common cause of induced myocardial infarction.
2. Relaxed spirit, a happy life, anything to be a stride.
3. Bath should pay special attention to. Not a meal or hunger in the circumstances bath. And the temperature is the best temperature, skin temperature heat will significantly expand blood vessels, blood flow surface, can cause heart and brain ischemia. Bath time should not be too long, hot bath general without ventilation, in this environment of relatively higher level of human metabolism, it is highly hypoxia, fatigue, especially elderly patients with coronary artery disease. Serious coronary heart disease than patients taking a bath, should be carried out to help others.
4. Climate change should beware. Strong cold air in the cold or under the influence of coronary artery spasm can occur secondary to thrombosis and caused acute myocardial infarction. Dramatic changes in climate, and low air pressure, coronary heart disease patients will be obvious discomfort. Internal data show that sustained low temperature, wind, rain is acute myocardial infarction one of the incentives. So exception bad weather, we should pay attention to patients with coronary heart disease or appropriate warm clothing and nitroglycerin widen the highest category of drug protection.
We need to understand and identify infarction aura symptoms and give timely treatment.
About 70% of myocardial infarction patients with aura symptoms, mainly as follows:
① suddenly obvious increase of angina pectoris;
② angina than ever to change the nature or use of nitroglycerin not ease;
③ pain accompanied by nausea, vomiting, sweating or apparent bradycardia;
④ angina attack occurs when heart failure thus increasing;
⑤ 1:00 electrocardiogram showed ST-segment depression or apparent rise of the T-wave inversion or high tip, or with arrhythmia;
⑥ elderly patients with coronary heart disease suddenly appeared the exact cause of the arrhythmia, heart failure, shock, respiratory difficulties or syncope, etc.. Threatened myocardial infarction prior to the onset of symptoms in more than one week, a small number of patients or even a few weeks in advance. About 40% of the patients before infarction occurred in 1-2 days.
Once these symptoms occur, we must treat it seriously. Strictly bedridden patients first, to keep quiet, to avoid excessive mental tension; sublingual nitroglycerin or nitroglycerin spray inhalation. Immediately associated with the nearby hospitals, while making preparations to the hospital. Transport must be able to smooth transit. Patients should avoid get up, the situation is relatively stable when transported by stretcher. Sustainable transit or intermittent use of nitroglycerin, oxygen, and should Jiaobi an aspirin (150-300 mg).
