The development of acute heart failure is usually a worsening of their pre-existing condition rather than a sudden onset of acute heart failure with no prior heart disease or risk factors.
It should be noted that AHF is not limited to patients with pre-existing heart conditions. There are also cases where patients may develop sudden signs and symptoms of heart failure as well.
What’s the Difference Between Acute and Chronic Heart Failure?
Acute heart failure is a clinical syndrome that comes about due to the failure of the heart to pump blood throughout a person’s body. The term “acute” refers to the rapid development of new symptoms or worsening of pre-existing symptoms of heart failure.
Patients who develop heart failure aren’t usually able to return to their previous baseline heart condition. This is because the damage that is done to the heart is usually permanent.
Heart failure is considered “chronic” if a patient has been suffering from heart failure for an extended period of time. Additionally, if the patient is treated and their condition does not deteriorate for at least a month, they are considered “stable.”
Heart failure is considered acute if the onset of symptoms occur suddenly. For instance, this occurs in the case of acute myocardial infarction (AMI), where the coronary arteries which supply blood to the heart are affected, causing ischemic injury to the heart.
