Heart failure generally refers to heart failure. There is no clear data on how long a person with grade 1 heart failure can live. Heart failure is usually categorized into grades 1 to 4, with grade 1 having milder symptoms compared to other grades of heart failure. After active treatment, the prognosis will be relatively good and the life cycle will be relatively long. Heart failure is a syndrome caused by diastolic and systolic dysfunction of the heart muscle, and the volume of blood discharged by the heart is insufficient to maintain the metabolic needs of the tissues. While heart failure is usually categorized into four grades, grade 1 heart failure for normal cardiac function, prognosis and life cycle, for other levels of heart failure patients better. However, there is no clear data on how well patients with grade 1 heart failure survive. Currently for heart failure can not be completely cured, only through early detection and early treatment, which is conducive to delaying the development of the disease, improve the quality of life of patients, and extend the life of patients.
