How much time is usually between the initial stage of heart failure and death is mainly related to the type of heart failure, the cause, the treatment and the individual factors of the patient, and should be analyzed specifically, not generalized. In the early stage of heart failure, patients may not have any uncomfortable symptoms, but may experience shortness of breath, wheezing and dyspnea after exercise or when they are emotionally agitated. If the patient is treated in time, the elimination of the cause of the disease generally does not affect the life expectancy, and can survive for a long time. However, in the case of acute heart failure, most patients can die within hours or days if they are not resuscitated in time. In addition, if the chronic heart failure is caused by ischemic cardiomyopathy, dilated cardiomyopathy, hypertrophic cardiomyopathy, viral myocarditis and other diseases, the patient needs to apply long-term drug therapy, and the 5-year survival rate is usually about 50%. Therefore, it is recommended that patients in the early stage of heart failure should go to the cardiology department of regular hospitals in time for consultation and examination, so that professional doctors can formulate reasonable treatment plans according to the specific conditions of the patients.
