Acute heart failure can not be generalized, patients with organic heart disease may shorten the survival time, there is a risk of sudden death, can clearly remove the cause of the disease can be long-term survival. Most of the acute heart failure has a primary cause, some patients may have organic heart disease, such as large acute myocardial infarction will occur in acute heart failure, patients with a high risk of sudden death, some patients after active treatment still have symptoms of heart failure exists, the survival time will be significantly shortened. Some patients develop heart failure with clear triggers, such as a large number of fluids in a short period of time, a large number of blood transfusions, etc. Some patients may have heart failure caused by a lung infection. If the primary cause can be removed and there is no organic damage to the heart, the patient’s survival time may not be affected, and the patient may survive for a long period of time. Acute heart failure should be treated quickly to remove the causative agent and avoid organic changes in the heart to prolong the patient’s survival time.
