The current incidence of acute coronary heart disease is on the rise, but many patients in the prevention and treatment of some misunderstandings, affecting the success rate of treatment. Cardiovascular disease ranks first in China’s population mortality rate, coronary heart disease in cardiovascular disease accounts for about one-third. In recent years, with the intensification of social competition and changes in dietary structure, the incidence of coronary heart disease, especially acute coronary heart disease, has been growing rapidly, but due to the lack of appropriate protection and first aid knowledge of many patients, they cannot receive timely and effective treatment in the first time, resulting in a higher mortality rate of this disease. Acute coronary heart disease patients have three main misconceptions: First, in the occurrence of angina pectoris and other acute coronary heart disease symptoms, it is treated as a general minor ailment, that a little rest can be relieved, and as a result, the optimal treatment time is missed. Second, in the event of acute myocardial infarction, thought to eat “fast-acting heart pills” and other ordinary drugs will be able to survive, rather than rushed to the hospital in a timely manner to rescue, so as to delay the treatment of life-threatening. Third, the heart surgery is considered dangerous, many people in the emergency life-saving still do not want to choose the less traumatic, effective cardiac intervention surgery, the result is a missed opportunity to save the life. Clinical research has confirmed that acute coronary heart disease patients in the onset of six hours of the best results. At present, about 90% of acute coronary heart disease patients in developed countries in the emergency treatment to choose cardiac intervention and other advanced surgical treatment methods, so that the mortality rate of this disease from 30% down to less than 5%. In our country, 70% of patients with acute coronary heart disease still choose medicine conservative treatment, which leads to various adverse consequences. Medical experts emphasize that patients with acute coronary heart disease should abandon the ideological concerns, with the help of modern medical achievements, and strive to prevent and treat the disease as early as possible to obtain the best therapeutic effect.
