If you&#8217;ve recently had an echocardiogram or other heart test, knowing what your EF means can help you better understand your heart health. This guide explains what a normal EF looks like, what can cause it to be low, how it&#8217;s measured, and when it&#8217;s time to talk with your healthcare provider.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Your heart beats around 100,000 times every day, pumping blood throughout your body to deliver oxygen and nutrients to every organ and tissue in your body. But how do doctors know whether your heart is pumping effectively? One of the most important measurements they use is called ejection fraction (EF).<\/strong><\/p>\n\n\n\n<p>If you&#8217;ve had an EKG, ECG, cardiac MRI, or another heart imaging test, you&#8217;ve probably seen an ejection fraction percentage in your results. While the number may seem confusing at first, understanding your EF can provide valuable insight into your cardiac health and help you better understand discussions with your cardiologist.<\/p>\n\n\n\n<p>In this article, we&#8217;ll explain what ejection fraction is, what&#8217;s considered normal, what causes a low EF, and why this measurement is so important.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Ejection Fraction?<\/h2>\n\n\n\n<p><strong>Ejection Fraction (EF)<\/strong>&nbsp;is the percentage of blood pumped out of the heart&#8217;s&nbsp;<strong>left ventricle<\/strong> with each heartbeat. The left ventricle is the main supplier of blood to the body.<\/p>\n\n\n\n<p>After each contraction, your heart fills with blood, then contracts again to pump that blood to the rest of your body. However, it doesn&#8217;t empty completely with each contraction. Instead, a healthy heart pumps out only a portion of the blood inside the left ventricle. The percentage of the blood that is pumped from the left ventricle is the Ejection Fraction.<\/p>\n\n\n\n<p>For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Before a heartbeat, the left ventricle contains&nbsp;<strong>120 milliliters (mL)<\/strong>&nbsp;of blood.<\/li>\n\n\n\n<li>During the heartbeat, it pumps out&nbsp;<strong>78 mL<\/strong>.<\/li>\n\n\n\n<li>The remaining&nbsp;<strong>42 mL<\/strong>&nbsp;stays in the ventricle.<\/li>\n<\/ul>\n\n\n\n<p>Since 78 is 65% of 120, the ejection fraction is&nbsp;<strong>65%<\/strong>.<\/p>\n\n\n\n<p>This percentage tells doctors how efficiently your heart is pumping blood.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Why Is Ejection Fraction Important?<\/h2>\n\n\n\n<p>Ejection fraction is an essential measurement for evaluating heart function.<\/p>\n\n\n\n<p>Doctors use EF to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Diagnose certain types of heart failure<\/li>\n\n\n\n<li>Assess damage after a heart attack<\/li>\n\n\n\n<li>Monitor cardiomyopathy and other heart diseases<\/li>\n\n\n\n<li>Evaluate whether treatments are improving heart function<\/li>\n\n\n\n<li>Determine if patients may benefit from implanted devices such as a implantable cardioverter-defibrillator (ICD)<\/li>\n<\/ul>\n\n\n\n<p>EF is an important measurement, but it is only one aspect of assessing heart health. Symptoms, physical exams, blood tests, imaging, and medical history are also essential for a complete diagnosis.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Is a Normal Ejection Fraction?<\/h2>\n\n\n\n<p>An ejection fraction between&nbsp;<strong>55% and 70% would be considered normal for a healthy adult<\/strong>.<\/p>\n\n\n\n<p>Here&#8217;s a general guide:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td><strong>Ejection Fraction<\/strong><\/td><td><strong>Interpretation<\/strong><\/td><\/tr><\/thead><tbody><tr><td><strong>55\u201370%<\/strong><\/td><td>Normal pumping function<\/td><\/tr><tr><td><strong>50\u201354%<\/strong><\/td><td>Slightly below normal<\/td><\/tr><tr><td><strong>41\u201349%<\/strong><\/td><td>Mildly reduced pumping ability<\/td><\/tr><tr><td><strong>40% or lower<\/strong><\/td><td>Reduced EF, often associated with heart failure<\/td><\/tr><tr><td><strong>35% or lower<\/strong><\/td><td>Significantly reduced function with increased risk of serious heart rhythm problems<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.aedcpr.com\/articles\/wp-content\/uploads\/2026\/08\/ejection-fraction-aedcpr.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"888\" src=\"https:\/\/www.aedcpr.com\/articles\/wp-content\/uploads\/2026\/08\/ejection-fraction-aedcpr-1024x888.png\" alt=\"Ejection Fraction explained\" class=\"wp-image-1497\" srcset=\"https:\/\/www.aedcpr.com\/articles\/wp-content\/uploads\/2026\/08\/ejection-fraction-aedcpr-1024x888.png 1024w, https:\/\/www.aedcpr.com\/articles\/wp-content\/uploads\/2026\/08\/ejection-fraction-aedcpr-300x260.png 300w, https:\/\/www.aedcpr.com\/articles\/wp-content\/uploads\/2026\/08\/ejection-fraction-aedcpr-768x666.png 768w, https:\/\/www.aedcpr.com\/articles\/wp-content\/uploads\/2026\/08\/ejection-fraction-aedcpr.png 1347w\" sizes=\"auto, (max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Can You Have Heart Failure with a Normal EF?<\/h2>\n\n\n\n<p>Yes.

An echocardiogram uses ultrasound waves to create moving images of the heart while measuring how much blood enters and leaves the left ventricle.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cardiac MRI<\/h3>\n\n\n\n<p>Provides extremely detailed images and highly accurate EF measurements.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Nuclear Stress Test<\/h3>\n\n\n\n<p>Evaluates both blood flow and pumping function using a small amount of radioactive tracer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cardiac CT<\/h3>\n\n\n\n<p>Sometimes used to assess heart anatomy and ventricular function.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cardiac Catheterization<\/h3>\n\n\n\n<p>During certain procedures, doctors can directly measure heart function and calculate EF.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Can Ejection Fraction Improve?<\/h2>\n\n\n\n<p>Depending on the underlying cause, EF can improve. If the underlying cause can be treated, the heart&#8217;s pumping ability can improve over time.<\/p>\n\n\n\n<p>Treatment may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Blood pressure medications<\/li>\n\n\n\n<li>ACE inhibitors or ARBs<\/li>\n\n\n\n<li>Beta blockers<\/li>\n\n\n\n<li>SGLT2 inhibitors<\/li>\n\n\n\n<li>Diuretics<\/li>\n\n\n\n<li>Treating blocked coronary arteries<\/li>\n\n\n\n<li>Repairing heart valves<\/li>\n\n\n\n<li>Managing diabetes<\/li>\n\n\n\n<li>Quitting smoking<\/li>\n\n\n\n<li>Limiting alcohol<\/li>\n\n\n\n<li>Weight loss<\/li>\n\n\n\n<li>Regular physical activity under medical supervision<\/li>\n<\/ul>\n\n\n\n<p>Some patients experience a significant improvement in EF quickly, while others see improvement after several months of treatment.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Can Lifestyle Changes Help?<\/h2>\n\n\n\n<p>Absolutely! Healthy lifestyle habits reduce strain on the heart and may help preserve or improve heart function.<\/p>\n\n\n\n<p>Consider these heart-healthy habits:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Eat a heart-healthy diet.<\/li>\n\n\n\n<li>Exercise regularly, if approved by your healthcare provider.<\/li>\n\n\n\n<li>Maintain a healthy weight.<\/li>\n\n\n\n<li>Control blood pressure, cholesterol, and blood sugar.<\/li>\n\n\n\n<li>Avoid smoking.<\/li>\n\n\n\n<li>Limit alcohol intake.<\/li>\n\n\n\n<li>Get enough sleep.<\/li>\n\n\n\n<li>Manage stress.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Does a Higher EF Always Mean Better Heart Health?<\/h2>\n\n\n\n<p>Absolutely not! EF is a tool used along with other diagnostics to determine overall heart health. It can also be used to determine the effect of underlying heart conditions.<\/p>\n\n\n\n<p>As stated earlier, some heart conditions, such as hypertrophic cardiomyopathy, can produce a very high EF while still impairing the heart&#8217;s ability to function normally.<\/p>\n\n\n\n<p>A person with a mildly reduced EF may have no issues, while someone with a normal EF may still have symptoms caused by other heart conditions. That&#8217;s why healthcare providers evaluate EF together with your symptoms, physical exam, and other test results.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">When Should You Ask Your Doctor About Your EF?<\/h2>\n\n\n\n<p>Knowing your EF can help provide an understanding of your overall heart health. If you&#8217;ve had a heart attack, have heart failure, cardiomyopathy, valve disease, or unexplained shortness of breath, you may want to inquire about your EF.<\/p>\n\n\n\n<p>Questions could include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What is my ejection fraction?<\/li>\n\n\n\n<li>Is it normal for someone my age?<\/li>\n\n\n\n<li>Has it changed since my last test?<\/li>\n\n\n\n<li>What caused it to be high or low?<\/li>\n\n\n\n<li>Do I need treatment or repeat testing?<\/li>\n<\/ul>\n\n\n\n<p>Understanding your EF can help you take a more active role in managing your cardiovascular health.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Final Thoughts<\/h2>\n\n\n\n<p>Ejection fraction is a key way to measure how well your heart works. It shows how much blood your heart&#8217;s left ventricle pumps out with each beat. A normal ejection fraction is usually between&nbsp;<strong>55% and 70%<\/strong>. If your ejection fraction is lower, it might mean your heart muscle is weaker, or you could have heart failure.<\/p>\n\n\n\n<p>Ejection fraction is important, but it is not the only thing that matters. Some people with a normal ejection fraction can still have heart failure, and some with a low ejection fraction may not have many symptoms. This is why a qualified healthcare provider should look at your ejection fraction along with your overall health.<\/p>\n\n\n\n<p>Understanding your ejection fraction can help you learn more about your heart, ask good questions at your doctor visits, and make choices that keep your heart healthy in the long run.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Ejection Fraction Calculator<\/h2>\n\n\n\n<form name=\"wpcalc\" id=\"wpcalc\" class=\"wpcalc\">\n\n    <div class=\"field is-horizontal\">\n\t\t<div class=\"field-label\"><label class=\"label\">Stroke volume<\/label><\/div>        <div class=\"field-body\">\n            <div class=\"field has-addons\">\n                <div class=\"control is-expanded\">\n\t\t\t\t\t<input class=\"input\" type=\"number\" step=\"0.001\" required>                <\/div>\n                <div class=\"control\">\n\t\t\t\t\t<div class=\"button is-outlined\">mL<\/div>                <\/div>\n            <\/div>\n        <\/div>\n    <\/div>\n\n    <div class=\"field is-horizontal\">\n\t\t<div class=\"field-label\"><label class=\"label\">End diastolic volume<\/label><\/div>        <div class=\"field-body\">\n            <div class=\"field has-addons\">\n                <div class=\"control is-expanded\">\n\t\t\t\t\t<input class=\"input\" type=\"number\" step=\"0.001\" required>                <\/div>\n                <div class=\"control\">\n\t\t\t\t\t<div class=\"button is-outlined\">mL<\/div>                <\/div>\n            <\/div>\n        <\/div>\n    <\/div>\n\n    <div class=\"field is-horizontal\">\n        <div class=\"field-label\">\n        <\/div>\n        <div class=\"field-body\">\n            <div class=\"field is-grouped\">\n\t\t\t\t<div class=\"control\"><input type=\"submit\" class=\"button\" value=\"Calculate\"><\/div><div class=\"control\"><input type=\"reset\" class=\"button\" value=\"Reset\"><\/div>            <\/div>\n        <\/div>\n    <\/div>\n\n    <div class=\"is-hidden\" id=\"calcResult\">\n\n        <div class=\"field is-horizontal\">\n\t\t\t<div class=\"field-label\"><label class=\"label\">Ejection fraction<\/label><\/div>            <div class=\"field-body\">\n                <div class=\"field has-addons\">\n                    <div class=\"control is-expanded\">\n\t\t\t\t\t\t<input type=\"text\" class=\"input\" id=\"calcResult1\" readonly>                    <\/div>\n                    <div class=\"control\">\n\t\t                <div class=\"button is-outlined\">%<\/div>                    <\/div>\n                <\/div>\n            <\/div>\n        <\/div>\n\n    <\/div>\n\n<\/form>\n\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What is a normal ejection fraction?<\/h3>\n\n\n\n<p>A normal ejection fraction is generally considered to be between&nbsp;<strong>55% and 70%<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can a low ejection fraction be reversed?<\/h3>\n\n\n\n<p>Sometimes.
