Understanding heart health is crucial for maintaining overall well-being. One key indicator of heart health is the ejection fraction (EF), a measure used to evaluate how well the heart is pumping blood. In this comprehensive guide, we will delve into what constitutes a normal ejection fraction by age, the implications for heart failure diagnosis and treatment, and how to maintain a healthy heart. We will also explore the expertise of Dr. Raghu, the best cardiologist in Hyderabad, in managing heart health issues such as cardiomyopathy and left ventricle function.

What Is Ejection Fraction?

Definition and Importance : Ejection fraction is a percentage that measures the amount of blood the left ventricle pumps out with each contraction. A normal ejection fraction typically ranges from 50% to 70%. This means that with each heartbeat, the left ventricle pumps out 50% to 70% of the blood within it. This measure is crucial for diagnosing and treating heart conditions, particularly heart failure.

How Ejection Fraction Is Measured?

Ejection fraction is usually measured using imaging techniques such as echocardiography (echo), cardiac MRI, or nuclear medicine scans. These tests provide detailed images of the heart, allowing doctors to calculate the ejection fraction accurately.

Normal Ejection Fraction by Age

Children and Adolescents : In children and adolescents, a normal ejection fraction is generally higher than in adults, often ranging from 60% to 75%. This higher range is due to the increased metabolic demands and robust cardiovascular health typical in younger individuals.

Adults : For adults, a normal ejection fraction is typically between 50% and 70%. As people age, there may be a slight decline in ejection fraction, but it usually remains within the normal range unless there is an underlying heart condition.

Elderly : In the elderly, a normal ejection fraction can be slightly lower but should still be above 50%. The aging heart may experience some decline in efficiency, but significant drops in ejection fraction can indicate potential heart issues that require medical attention.

Factors Affecting Ejection Fraction

Cardiomyopathy : Cardiomyopathy refers to diseases of the heart muscle that can affect the heart’s ability to pump blood effectively. This condition can lead to a reduced ejection fraction, signaling the need for heart failure diagnosis and treatment. Cardiomyopathy can be inherited or caused by other factors such as high blood pressure, heart valve disease, or chronic alcohol consumption.

Left Ventricle Function : The left ventricle is the heart’s main pumping chamber, and its function is critical for maintaining a healthy heart. Any damage or weakening of the left ventricle, such as from a heart attack, can significantly lower the ejection fraction and compromise overall heart function.

Heart Failure : Heart failure occurs when the heart is unable to pump blood effectively, leading to symptoms such as shortness of breath, fatigue, and fluid retention. Heart failure can be a result of various conditions, including cardiomyopathy and left ventricle dysfunction. Measuring ejection fraction is a key part of diagnosing and treating heart failure.

Heart Failure Diagnosis and Treatment

Diagnostic Procedures : To diagnose heart failure, doctors use a combination of medical history, physical examination, and diagnostic tests. Ejection fraction measurement is a critical component of this process. Other tests may include blood tests, chest X-rays, and electrocardiograms (ECGs).

Treatment Options : Treatment for heart failure aims to improve symptoms, enhance quality of life, and prevent further heart damage. Common treatments include:

Medications : ACE inhibitors, beta-blockers, diuretics, and other medications help manage heart failure symptoms and improve heart function.

Lifestyle Changes : Diet, exercise, and smoking cessation are crucial for maintaining a healthy heart.

Surgery and Procedures : In some cases, procedures such as coronary artery bypass grafting (CABG), heart valve repair, or implantation of devices like pacemakers or defibrillators may be necessary.

Role of Ejection Fraction in Treatment

Ejection fraction is a key determinant in the treatment plan for heart failure. It helps doctors assess the severity of the condition and monitor the effectiveness of treatment. Regular monitoring of ejection fraction can guide adjustments in therapy to ensure optimal heart function.

Maintaining a Healthy Heart

Lifestyle Recommendations : Maintaining a healthy heart involves a combination of lifestyle choices and regular medical check-ups. Here are some recommendations to keep your heart healthy:

Healthy Diet : Eat a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Limit intake of saturated fats, trans fats, and sodium.

Regular Exercise : Aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity each week, along with muscle-strengthening exercises.

Avoid Smoking : Smoking is a major risk factor for heart disease. Quitting smoking can significantly improve heart health.

Manage Stress : Chronic stress can negatively impact heart health. Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises.

Regular Check-ups : Regular visits to your healthcare provider can help detect and manage heart health issues early.

Importance of Monitoring Ejection Fraction

Regular monitoring of ejection fraction is essential, especially for individuals with a history of heart disease or risk factors such as hypertension and diabetes. This monitoring can help detect changes in heart function early, allowing for timely intervention and treatment.


Understanding what constitutes a normal ejection fraction by age is vital for maintaining heart health and diagnosing potential heart issues. Ejection fraction is a key measure used to evaluate the heart’s pumping efficiency and is critical in diagnosing and treating heart failure. Conditions such as cardiomyopathy and left ventricle dysfunction can significantly impact ejection fraction and overall heart function.
