Ejection Fraction and the Aging Heart

What Retirees Should Know

For many adults entering retirement, health decisions become more deliberate. The goal is no longer simply to treat illness, but to preserve energy, independence, mobility, and quality of life. One important measure that can help clarify how well the heart is functioning is known as ejection fraction, often abbreviated as EF

At Dr. Tun’s practice in Vero Beach, conversations about heart health are approached in practical terms. Understanding EF can help patients ask better questions, recognize meaningful symptoms, and participate more confidently in decisions about their care.

What Does Ejection Fraction Measure?

The heart’s left ventricle is responsible for pumping oxygen-rich blood to the body. Each time the heart contracts, it pushes out a portion of the blood contained in that chamber.

Ejection fraction is the percentage of blood released from the left ventricle with each heartbeat.

An EF of 60%, for example, means the heart pumps out approximately 60% of the blood in the ventricle during each contraction. The heart does not normally empty completely, so an EF below 100% is expected.

What Is Considered a Healthy EF?

A typical left ventricular ejection fraction is generally in the range of 55% to 70%.

An EF between 41% and 54% may suggest mildly reduced pumping strength. A result of 40% or lower can be associated with a weakened heart muscle and may support a diagnosis of certain forms of heart failure.

An unusually high EF can also warrant attention. The number should always be interpreted in context, alongside symptoms, medical history, imaging findings, and other clinical information.

Why EF Matters More With Age

Aging itself does not automatically cause heart failure, but it does increase the likelihood of conditions that can place additional strain on the heart.

These may include high blood pressure, coronary artery disease, diabetes, atrial fibrillation, prior heart attack, and heart valve disorders. Over time, these conditions can alter the heart’s ability to fill, relax, or pump efficiently.

EF helps physicians evaluate one aspect of this function. It can also provide a useful baseline for monitoring change over time.

A Normal EF Does Not Rule Out Heart Failure

One of the most important points for patients to understand is that heart failure can occur even when EF is within the normal range.

In some older adults, the heart contracts normally but does not relax or fill properly. This is sometimes referred to as heart failure with preserved ejection fraction.

For that reason, a normal EF should not be viewed as a complete guarantee that the heart is functioning optimally. Symptoms and overall clinical assessment remain essential.

Symptoms That Deserve Attention

Changes in stamina are often attributed to aging, but some may reflect cardiovascular disease.

Patients should speak with their physician about symptoms such as:

• Shortness of breath during activity or while lying flat
• New or increasing fatigue
• Swelling in the feet, ankles, or lower legs
• Reduced exercise tolerance
• Unexplained weight gain over several days
• Persistent coughing, particularly at night
• A sense of pressure, heaviness, or rapid heartbeat
• These symptoms do not always indicate heart failure, but they should not be dismissed.

How EF Is Measured

The most common test used to estimate ejection fraction is an echocardiogram, which uses ultrasound to create moving images of the heart.

An echocardiogram can provide information about:

Pumping strength
Chamber size
Heart valve function
Wall motion
Evidence of fluid or structural abnormalities
In selected cases, a cardiac MRI, nuclear imaging study, CT scan, or cardiac catheterization may provide additional information.

Can Ejection Fraction Improve?

In some patients, EF can improve when the underlying cause is identified and treated.

Treatment may include better blood pressure control, management of diabetes or cholesterol, medications that reduce strain on the heart, treatment of abnormal rhythms, correction of valve disease, or lifestyle changes tailored to the individual.

The most effective plan depends on the cause of the reduced EF, the presence of symptoms, and the patient’s overall health.

Heart Health in the Context of Geriatric Care

Older adults often manage several medical concerns at once. Heart disease may overlap with kidney function, balance problems, medication side effects, sleep disorders, arthritis, cognitive changes, or reduced mobility.

This is where comprehensive geriatric care becomes especially valuable.

Dr. Tun evaluates heart health within the broader context of each patient’s goals, daily function, medications, and quality of life. The objective is not simply to improve a test result, but to help patients remain active, independent, and engaged in the life they have built.

Questions to Ask at Your Next Visit

Patients may find it helpful to ask:

• What is my ejection fraction?
• Has it changed over time?
• Is my heart filling and relaxing normally?
• Could my medications affect my blood pressure, heart rate, or fluid balance?
• Are my symptoms consistent with a heart condition?
• Would an echocardiogram or cardiology evaluation be appropriate?

Thoughtful questions often lead to more productive medical conversations.

Geriatric Care for Retirees in Vero Beach

Retirement offers the opportunity to be more intentional about health, prevention, and long-term well-being.

For older adults in Vero Beach and the surrounding Treasure Coast, Dr. Tun provides personalized geriatric care focused on the realities of aging, including heart health, medication management, chronic disease, mobility, memory concerns, and preventive planning.

Understanding your ejection fraction is one useful step.

Understanding how your heart fits into your overall health is even more important.
