What Is Ejection Fraction?
The ejection fraction represents the percentage of blood pumped out of the left ventricle when the heart contracts.
In a healthy heart, the ejection fraction ranges from around 52%74%.
What Causes Congestive Heart Failure?
CHF usually develops after conditions weaken the heart muscles.
However, it’s a more uncommon condition with different causes and symptoms.
BMI is a dated, flawed measure.
It does not take into account factors such asbody composition, ethnicity, sex, race, and age.
Stages of Heart Failure
CHF is usually an irreversible condition that gets worse over time.
The stages of heart failure describe the severity of the conditions.
Even walking across your home may become difficult because of problems moving oxygen through the body.
Still, with an effective treatment plan, you could slow the progression of the disease.
Ask your healthcare professional for a referral or connect through organizations like the American Heart Association.
