Heart failure is a variety of cardiac structural or functional diseases resulting in ventricular filling and (or) ejection function is impaired, cardiac output can not meet the body’s tissue metabolism needs, to the pulmonary circulation and (or) the body circulation stagnation, organs and tissues with insufficient blood perfusion as a group of clinical manifestations of syndromes, the patient’s life expectancy according to the cause of the primary disease and the severity of different differences, such as cardiomyopathy, arrhythmia and so on. 1. Cardiomyopathy: When the primary disease is cardiomyopathy, the development of heart failure is already in a more advanced stage, and heart failure may be the cause of the patient’s death, but the time according to the patient’s own state and the level of diagnosis and treatment is slightly different. 2. Arrhythmia: If there is no malignant arrhythmia, and the arrhythmia is prioritized by means of radiofrequency ablation and other means, heart failure can be effectively controlled in a short period of time, and the patient’s life expectancy is basically the same as that of a normal person. 3. Acute exacerbation of chronic heart failure: If heart failure is suddenly exacerbated within a short period of time due to certain triggers, the patient’s life may be in danger, with a low survival rate and a relatively short survival period, with common triggers such as infections and severe emotional fluctuations. If there is any discomfort, it is recommended to go to the hospital in time for treatment.
