Study Notes
Heart Failure (HF)
- Heart Failure (HF) is a condition where the heart is unable to pump enough blood to meet the body's needs.
Ejection Fraction (EF)
- Ejection Fraction (EF) is a measure of the heart's pumping function.
- Reduced Ejection Fraction (EF) is defined as an EF of less than 40%.
Heart Failure with Reduced Ejection Fraction (HFrEF)
- HFrEF is a type of heart failure characterized by systolic dysfunction.
- Excessive afterload, such as high blood pressure, can cause HFrEF.
- In HFrEF, the end-systolic volume (ESV) increases in the Left Ventricular Pressure-Volume Loop.
Heart Failure with Preserved Ejection Fraction (HFpEF)
- HFpEF is a type of heart failure characterized by preserved systolic function but impaired diastolic function.
- In HFpEF, at least 50% of blood is ejected from the left ventricle during systole.
Impaired Ventricular Relaxation and Filling
- HFpEF is associated with impaired ventricular relaxation and filling.
Excessive Afterload
- Excessive afterload, such as high blood pressure, can cause HFrEF.
Reduced Ejection Fraction (EF)
- A reduced Ejection Fraction (EF) indicates that the heart is having trouble pumping blood effectively.
End-Systolic Volume (ESV)
- In HFrEF, the end-systolic volume (ESV) increases in the Left Ventricular Pressure-Volume Loop.
