LVEF <40% Congestive heart failure
What is a Low Left Ventricular Ejection Fraction (LVEF) and Congestive Heart Failure?
Low Left Ventricular Ejection Fraction (LVEF) is an important measurement in determining the function of the left side of the heart. The LVEF is commonly used to monitor conditions such as congestive heart failure (CHF). A normal LVEF ranges between 55-75%, with 50% and lower indicating that the heart is not pumping effectively.
Congestive heart failure is a condition in which the heart is not able to pump blood efficiently. As a result, the blood becomes congested in the heart, lungs and other body parts. Symptoms of congestive heart failure include shortness of breath, fatigue, swelling in the feet, ankles and legs, and difficulty exercising.
Effects of LVEF <40% on Congestive Heart Failure
When left ventricular ejection fraction (LVEF) is less than 40%, this means that the individual is in a progressed stage of congestive heart failure. The weakened pumping capacity of the heart affects the entire body. With LVEF <40%, individuals are at even greater risk for blood clots, stroke, or sudden cardiac death.
The heart may be unable to keep up with the demands of the body and start to fail, leading to many other symptoms. As the heart weakens, individuals may experience shortness of breath, even when lying down, fatigue, and increased swelling. As the oxygen supply throughout the body is reduced, chest pain can occur.
Treatment Options for LVEF <40% and Congestive Heart Failure
When LVEF is low, the focus of treatment is to reduce damage to the heart muscle and improve pumping capacity. Treatment can include:
- Medication to reduce the workload on the heart muscle
- Lifestyle changes to reduce the risk of further damage to the heart
- Surgery or device therapy to support heart function
- Dietary changes to reduce the strain on the heart
- Supplements to improve heart health
- Alternative therapies for improved cardiovascular health
Treatment for individuals with LVEF < 40% and congestive heart failure will depend on the individual’s overall health and the severity of their condition. It is important to speak to a medical professional to determine the most effective approach to treatment.
