The survival time of heart failure patients varies depending on the severity of symptoms and the effectiveness of treatment. Early stage heart failure patients can survive for several years to decades with scientific diagnosis and treatment, while patients with end-stage heart failure have a shorter survival time. Early stage heart failure patients with mild impairment of cardiac function need timely drug treatment to slow down the development of heart failure, and under normal circumstances after scientific diagnosis and treatment will have little impact on life expectancy. For severe end-stage heart failure patients, heart function is poor, the body due to long-term chronic consumption of disease tolerance is poor, once there are triggers leading to acute exacerbation of heart failure, cardiac function can be rapidly decreased and sudden death, survival rate and survival period are lower. For heart failure patients must be under the guidance of the doctor strict care treatment, in order to prolong life and improve the quality of survival.
