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, such as in the case of acute myocardial infarction (AMI), where the coronary arteries which supply blood to the heart can be affected, causing ischemic injury to the heart.
What Causes Heart Failure?
This condition comes about when there are anatomical (structural) and/ or functional abnormalities within the heart, causing:
- A decrease in the amount of blood the heart is able to pump out per beat. This causes the patient’s systemic symptoms such as lower limb swelling, difficulty of breathing, and tiredness.
- Places stress on the heart as it tries to compensate (increased cardiac pressures).m As the heart continues to compensate, the cells of the heart may experience ischemic injury, causing the chest pain.
