Myocardial infarction cannot be cured. Myocardial infarction is a complete blockage of the coronary arteries, after the blood vessels are completely blocked, the heart muscle innervated by the blocked blood vessels will be necrotic, the heart muscle can not be completely restored to normal after necrosis, and it will be replaced by scar tissue later on, and the heart muscle contraction ability will be lost. Myocardial infarction patients with small blood vessel blockage of the heart will have less impact on cardiac function, large myocardial infarction will cause myocardial contractility to decline, and even serious cardiac insufficiency will occur, patients with an elevated risk of sudden death, the quality of life will be significantly reduced. After the occurrence of myocardial infarction should be scrambled to rescue, in the acute stage of myocardial infarction can be thrombolytic therapy, the conditions of the hospital can also be emergency stent implantation, can quickly open the blocked coronary arteries, and provide blood to the diseased blood vessels in a timely manner, so that the diseased blood vessels recirculation. Patients with coronary heart disease should be given regular treatment under the guidance of a physician, adhere to the medication, reduce the incidence of myocardial infarction; discomfort, timely consultation, active treatment, so as not to delay the condition.
