Understanding Ejection Fraction
Ejection Fraction (EF) is a measurement of the percentage of blood leaving your heart's main pumping chamber with each beat. While the term can apply to either the left or right ventricle, it most commonly refers to the left ventricular ejection fraction (LVEF), as the left ventricle is responsible for pumping oxygen-rich blood to the rest of the body. It's a key indicator used by doctors to assess heart function.
Contrary to what some might assume, even a healthy heart does not pump out 100% of the blood in the ventricle during a single beat. This is why a normal EF is a percentage rather than a total clearance.
What is a Good Ejection Fraction for a 70-Year-Old Man?
For a man in his 70s, a good ejection fraction falls within the normal range established for adults. According to the Cleveland Clinic, a normal LVEF for men is between 52% and 72%. A score within this range is a positive sign of healthy cardiac function. However, an EF measurement is just one piece of the puzzle. A doctor will consider a person's overall health, medical history, and other factors alongside this number.
It is important to remember that age-related changes can affect heart health, and a person's EF is a dynamic measure that can be influenced by various conditions. For this reason, regular monitoring and open communication with a healthcare provider are essential for seniors.
Ejection Fraction Ranges and What They Mean
The EF measurement is categorized into several ranges, each with different clinical implications. These ranges apply universally, regardless of age, but seniors face an increased risk of conditions that can lower their EF.
- Normal: For men, this is typically 52% to 72%. It indicates the heart is functioning effectively.
- Borderline/Mildly Reduced: An EF between 41% and 51% (for men) is considered mildly reduced. It may or may not indicate heart failure but warrants further investigation.
- Reduced: An EF of 40% or lower is typically a sign of heart failure or cardiomyopathy, a disease of the heart muscle.
- Heart Failure with Preserved Ejection Fraction (HFpEF): This condition, common in older adults, occurs when the heart muscle becomes stiff and thick, holding less blood than usual. Even if the EF is in the normal range, the heart may not pump enough blood to meet the body's needs.
Comparison of Ejection Fraction Ranges
| Category | LVEF Range (Men) | Clinical Implication |
|---|---|---|
| Normal | 52% - 72% | Healthy, efficient heart pump |
| Mildly Reduced | 41% - 51% | May indicate early heart damage or risk of heart failure |
| Reduced | Below 40% | Typically signifies heart failure (HFrEF) or cardiomyopathy |
| High | Above 75% | Can be a sign of certain heart conditions, such as hypertrophic cardiomyopathy |
Symptoms Associated with Abnormal Ejection Fraction
If an ejection fraction is low, it can lead to noticeable symptoms that significantly impact a person's quality of life. For seniors, these symptoms can sometimes be mistaken for general aging, making awareness crucial. Some common signs include:
- Fatigue or general weakness
- Shortness of breath, especially with exertion
- Swelling in the ankles, feet, or abdomen
- A rapid or irregular heartbeat (palpitations)
- Reduced ability to exercise or perform daily activities
If you or a loved one experience any of these symptoms, it is crucial to consult with a doctor for a proper diagnosis and treatment plan.
Maintaining Optimal Heart Health at 70 and Beyond
While you cannot change your age, you can take proactive steps to improve and maintain heart health, potentially stabilizing or improving your ejection fraction. For a 70-year-old man, these measures are particularly important:
- Prioritize Regular Exercise: A sedentary lifestyle is a significant risk factor for heart disease. Aim for at least 150 minutes of moderate-intensity aerobic activity per week, such as brisk walking, swimming, or cycling. Including some muscle-strengthening activities is also beneficial. Before starting any new exercise regimen, consult your doctor.
- Eat a Heart-Healthy Diet: Focus on consuming a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Limiting saturated and trans fats, sodium, and added sugars is vital, especially as older adults may be more sensitive to sodium.
- Manage Underlying Conditions: Conditions like high blood pressure, diabetes, and high cholesterol can all negatively affect heart function. Following a prescribed treatment plan, which may include medication and lifestyle changes, is essential.
- Quit Smoking: If you smoke, quitting is one of the most impactful steps you can take for your heart health.
- Control Stress: Chronic stress can increase blood pressure and heart rate, which can damage artery walls over time. Practicing stress-management techniques such as deep breathing, meditation, or engaging in enjoyable hobbies is important.
- Get Adequate Sleep: Most adults, including seniors, need 7 to 9 hours of quality sleep per night. Poor sleep is linked to heart health issues.

Conclusion
For a 70-year-old man, a good ejection fraction is within the normal adult range of 52% to 72%, indicating a healthy and efficient heart pump. While an EF is a critical measure of heart function, it is just one component of overall cardiac health. As the body ages, risk factors for heart conditions often increase, making it more important than ever to monitor and maintain good cardiovascular health through regular check-ups, a healthy lifestyle, and proactive management of any underlying conditions.
