Understanding Ejection Fraction: Normal vs Optimal Ranges

?What is Ejection Fraction?

Ejection Fraction (EF) is the percentage of blood pumped out of the left ventricle with each heartbeat. It is a key measure of cardiac function, typically assessed via echocardiography or cardiac imaging. Normal EF ranges from 50–100%, with values below 40% generally indicating reduced heart function.

!Why It Matters

EF is a fundamental indicator of how effectively your heart pumps blood to the body. Reduced ejection fraction may suggest weakened heart muscle function and can be associated with increased risk of heart failure, arrhythmias, and other cardiovascular complications. Monitoring EF helps guide treatment decisions and assess overall cardiovascular health.

Reference Ranges

Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.

Symptoms of Imbalance

• Shortness of breath, especially during activity
• Fatigue or weakness
• Swelling in legs, ankles, or abdomen
• Chest discomfort or pressure
• Irregular or rapid heartbeat

How to Improve Your Levels

• 1Follow a heart-healthy diet low in sodium and saturated fats
• 2Engage in regular, moderate aerobic exercise as recommended by your cardiologist
• 3Maintain a healthy weight and manage blood pressure
• 4Reduce stress through relaxation techniques or meditation
• 5Adhere to prescribed cardiac medications (ACE inhibitors, beta-blockers, etc.)
• 6Limit alcohol consumption and avoid smoking

When to Test

EF should be assessed if you have symptoms of heart failure, a history of heart disease, high blood pressure, diabetes, or have undergone cardiac events. It may also be monitored periodically in individuals with known reduced EF or those on cardiotoxic medications.
