Myocardial fibrosis can not be sure how many years to live, survival time varies from person to person. Depending on the cause of the disease, the severity of the disease, the treatment program, the patient’s personal physical condition and other factors, if the diagnosis and treatment in a timely manner, the condition of the lesser generally longer survival period, and vice versa, shorter, and in severe cases will cause death. The most common forms of cardiac fibrosis are myocardial infarction and heart failure. Myocardial infarction patients myocardial cell death, fibrosis scar formation to replace the necrotic myocardial tissue, myocardial infarction needs to be based on the scope of infarction and other predictions of the survival period, such as minor regular use of medication is generally a longer period of survival, extensive myocardial infarction may be life-threatening. After myocardial injury from a variety of causes, excessive cardiac fibrosis results in increased myocardial stiffness, cardiac systolic or diastolic dysfunction, and heart failure. When a patient develops cardiac fibrosis, he or she should be examined promptly to clarify the cause of the disease, be treated under the guidance of a doctor, and maintain a good state of mind to maximize life.
