Myocardial infarction is a rapid and serious clinical manifestations of coronary heart disease, mainly due to coronary artery was clogged by thrombus or coronary spasm, myocardial ischemia and death. The high incidence of winter because of cold stimulation, so that the body's Sympathetic nervous system increased excitability, increased body phenol-amine secretion, prompting limb vasoconstriction, heart rate, increased heart workload, increased oxygen consumption, myocardial ischemia and hypoxia is easy, causing angina pectoris. At the same time, sympathetic excitement Phenolic amine and children can lead to coronary spasm itself, low temperature and easy aggregation of platelets, increased blood viscosity, easy to form thrombus, but also lead to myocardial infarction is an important reason.
In addition, people reduce activity in winter, the value of the winter tonic season often eat less hyperactivity, will lead to elevated blood lipids, blood viscosity increases.In addition, when the room temperature dropped below 10 ℃, people will feel depressed, depressed Also easy to induce angina, severe myocardial infarction occurs.
In view of the adverse factors that tend to induce myocardial infarction during the cold season, cardiovascular diseases, especially those with coronary heart disease, are required to pay special attention to the weather forecast and arrange work and rests reasonably in cold winter months. Insist on the guidance of a doctor Medication, such as low-dose aspirin or dipyridamole, etc. World Health Organization recommends that: winter room temperature should not be less than 18 ℃, for the elderly and patients with coronary heart disease should be increased by 2-3 ℃ is appropriate.
In the cold coming, should promptly increase the cap, clothing, bedding and reduce out.The diet should be properly controlled intake of salt and fat, eat more fresh vegetables and fruits, to avoid over exertion and emotional.T 40 years of age, with the crown Family history of heart disease, hypertension, hyperlipidemia and other susceptible factors, cold winter should pay attention to warm and cold, so as not to lead to future troubles.
