A low ejection fraction (or low EF) is typically 45 or less and can be evidence of heart failure or cardiomyopathy (a disease of the heart muscle). The heart’s ejection fraction (EF) refers to the amount – or percentage – of blood pumped (or ejected) out of the heart’s left ventricle with each contraction.
This is heart failure with a reduced ejection fraction. This occurs when one of your heart’s four chambers can’t contract properly. Symptoms might include shortness of breath, exhaustion, or heart palpitations. HFpEF (diastolic dysfunction). This is heart failure with a preserved, or normal, ejection fraction.
An ejection fraction range between 41 and 51 percent for men and between 41 and 53 percent for women is classified as mildly reduced. It could be a sign of heart damage, perhaps from a heart condition or a previous heart attack. Sign of heart failure. An LVEF below 40 percent is heart failure with reduced ejection fraction (HFrEF).
Ejection fraction is a test your doctor can use to determine the percentage of blood that leaves the left ventricle each time your heart beats, and to understand how well your heart works. Ejection fraction can help diagnose heart failure. A diagram of the heart, with the left and right ventricles in the lower section of the heart.
ICD-10 code I50. 2 for Systolic (congestive) heart failure is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
150.1 is revised, to “Left ventricular failure, unspecified.” I50. 2 Systolic (congestive) heart failure adds two definitions: Heart failure with reduced ejection fraction [HFrEF]
The proposed nomenclature based on left ventricular ejection fraction defines “heart failure with reduced ejection fraction” (HFrEF) as LVEF of <40%, “heart failure with mildly reduced ejection fraction” (HFmrEF) as 40% ≤ LVEF < normal, and “heart failure with normal ejection fraction” (HFnEF) as LVEF of ≥55% in men ...

A low ejection fraction (or low EF) is typically 45 or less and can be evidence of heart failure or cardiomyopathy (a disease of the heart muscle). The heart's ejection fraction (EF) refers to the amount – or percentage – of blood pumped (or ejected) out of the heart's left ventricle with each contraction.
Cardiac output equals the volume of blood pumped by the heart per minute, whereas stroke volume (SV) is the amount pumped on a single beat.
Ejection fraction is an indicator of heart strength. It measures the amount of oxygen-rich blood pumped out to the body with each heartbeat. A low ejection fraction is typically a sign of heart failure. With treatments and self-care, it's possible to raise your ejection fraction back into normal range.

Heart failure with reduced ejection fraction (HFrEF), also called systolic failure: The left ventricle loses its ability to contract normally. The heart can't pump with enough force to push enough blood into circulation.
systolic heart failure or heart failure with reduced ejection fraction (HFrEF) is a complex clinical syndrome characterized by structural and/or functional impairment of the left ventricle, resulting in a decrease in heart pump function (left ventricular ejection fraction ≤ 40%), which is associated with an ...
People with heart failure with reduced ejection fraction (HFrEF) have an EF that is 40 to 50 percent or lower. This is also called systolic heart failure. People with heart failure with preserved ejection fraction (HFpEF) do not have much of a change in their ejection fraction.
Diastolic heart failure is a clinical syndrome characterized by the symptoms and signs of heart failure, a preserved ejection fraction (EF), and abnormal diastolic function.
If your ejection fraction is low, below 50% , your heart is no longer efficiently pumping blood to meet your body's needs.
However, it can be triggered by a heart attack, coronary artery disease, diabetes and/or uncontrolled high blood pressure, which can be caused or worsened by: Alcohol or drug abuse. An unhealthy diet, high in saturated fat, sugar and salt. Lack of exercise.
Risk Factors. Risk factors that could contribute to low ejection fraction include: Congenital or familial heart valve disease or cardiomyopathy: Some people are born with, or develop inherited forms of, malformed or dysfunctional heart valves or weakening of the heart muscle.

The EF is an important measurement that physicians use to determine how well your heart is pumping out blood and to diagnose or track heart failure. A normal range for heart ejection fraction may be between 50 and 70. Baptist Health is known for advanced, superior care for patients with heart problems and the diagnosis, ...
Getting the appropriate amount and intensity of exercise, losing weight, quitting smoking, reducing salt or excess fluids, and eating a healthier diet are some of the recommendations for improving low EF.
While most cases of low EF cannot be directly prevented, there are ways to reduce your chances of developing a heart condition that leads to it. Follow these prevention tips to help lower your risk of developing low EF:
Left ventricular ejection fraction (EF), generally measured by echocardiography, remains the cornerstone of HF diagnosis, characterization, prognosis, patient triage and treatment selection. The clinical use of EF has flaws, which are described below in detail. Advanced multivariable analytics (such as machine learning and other methods for patient clustering and phenotyping) as well as other parameters have demonstrated a better calibration and discrimination for survival than the use of EF alone13. Nevertheless, EF remains the primary parameter for HF characterization and the primary inclusion criterion for clinical trials of HF. Until better measurements than the EF are available that meet all the needs for HF characterization, the data described in this Review might be relevant for both clinicians and clinical trialists6,14,15,16.
Left ventricular ejection fraction (EF) remains the major parameter for diagnosis, phenotyping, prognosis and treatment decisions in heart failure. The 2016 ESC heart failure guidelines introduced a third EF category for an EF of 40–49%, defined as heart failure with mid-range EF (HFmrEF). This category has been largely unexplored compared with heart failure with reduced EF (HFrEF; defined as EF <40% in this Review) and heart failure with preserved EF (HFpEF; defined as EF ≥50%). The prevalence of HFmrEF within the overall population of patients with HF is 10–25%. HFmrEF seems to be an intermediate clinical entity between HFrEF and HFpEF in some respects, but more similar to HFrEF in others, in particular with regard to the high prevalence of ischaemic heart disease in these patients. HFmrEF is milder than HFrEF, and the risk of cardiovascular events is lower in patients with HFmrEF or HFpEF than in those with HFrEF. By contrast, the risk of non-cardiovascular adverse events is similar or greater in patients with HFmrEF or HFpEF than in those with HFrEF. Evidence from post hoc and subgroup analyses of randomized clinical trials and a trial of an SGLT1–SGLT2 inhibitor suggests that drugs that are effective in patients with HFrEF might also be effective in patients with HFmrEF. Although the EF is a continuous measure with considerable variability, in this comprehensive Review we suggest that HFmrEF is a useful categorization of patients with HF and shares the most important clinical features with HFrEF, which supports the renaming of HFmrEF to HF with mildly reduced EF. Heart failure with mid-range or mildly reduced ejection fraction (HFmrEF) accounts for up to 25% of patients with heart failure. In this Review, Lund and colleagues provide a comprehensive overview of the epidemiology, clinical profile, prognosis and potential treatment of patients with HFmrEF.
HF with reduced EF (HFrEF; defined as EF <40%) is well characterized, and effective therapies for patients with HFrEF are available. The term HF with preserved EF (HFpEF) has long been used to describe patients with HF signs and symptoms and an EF that was variably defined as >40%, >45% or ≥45%, or >50% or ≥50%. For these patients, no clinical trial to date has demonstrated clear benefits of therapy17. In the 2016 ESC HF guidelines, a separate entity, HF with mid-range EF (HFmrEF; defined as EF 40–49%), was introduced to foster research in this EF range, which has been less investigated than HFrEF (EF <40%) and HFpEF (EF ≥50%)6. Extensive subsequent research confirms that HFmrEF has some intermediate features between HFrEF and HFpEF but also suggests distinct similarities between HFmrEF and HFrEF that warrant the term HF with ‘mildly reduced’ EF, as has also been proposed by other authors in the past 2 years18,19,20. In this Review, we provide a comprehensive overview of the epidemiology, clinical profile, prognosis and potential treatment of HFmrEF, which we define as HF with mildly reduced EF.
On the basis of contemporary trials and definitions, HFmrEF might be defined as an EF of 41–49%.
These arguments support the current redefinition of HFmrEF as HF with mildly reduced EF instead of HF with mid-range EF.
In general, inducibility is more useful in identifying patients for risk of ventricular tachyarrhythmias in those with well-preserved ventricular function than in those with moderately to severely reduced ventricular function. In MADIT-II, electrophysiological testing was carried out in 593 patients who had an ICD, and 36% of these patients were inducible into ventricular tachycardia or ventricular fibrillation. Inducibility into ventricular tachyarrhythmias was associated with greater appropriate ICD therapy for ventricular tachycardia but reduced ICD therapy for ventricular fibrillation during follow-up than patients who were not inducible. These MADIT-II findings suggest that in patients with EF ≤0.30, inducibility with electrophysiological testing is not clinically useful in identifying patients who should receive an ICD for the prevention of sudden cardiac death.
The limited sensitivity of EF to predict risk of sudden death also is illustrated by the European Autonomic Tone and Reflexes After Myocardial Infarction (ATRAMI) study (1284 patients enrolled within 1 month of acute MI who underwent multiple risk stratification tests). 25 In this study, the mean EF was 49%. 25 After an average follow-up of 21 months, a total of 49 deaths occurred. In only 22 of those experiencing cardiac arrest after infarction was the EF <35% when measured early after MI.
The available data indicate that ICD therapy provides a meaningful and significant reduction in mortality in high-risk patients with ischemic and nonischemic cardiomyopathy as part of primary- and secondary-prevention strategies. These populations contain considerable risk heterogeneity, with clear survival benefit in patients with EFs ≤0.30, but not in patients with EFs >0.30. The meta-analysis findings indicate that sicker patients (ie, those with lower EFs) benefit more from ICD therapy. 17 The MUSTT study indicates that those with an EF <0.30 are at greater mortality risk than those with higher EFs, 15 so it is likely that the ICD benefit in MUSTT was concentrated in those with lower EFs.
The findings from relevant randomized defibrillator trials indicate that the ICD saves lives in a spectrum of cardiac patients with left ventricular dysfunction and an EF ≤0.30. Within this large population of potential ICD recipients, some patients should not receive an ICD because of co-morbid conditions. Attempts to identify low-risk patients who are unlikely to benefit from ICD therapy are in progress. At present, I recommend that ICDs be implanted in patients with an EF ≤0.30 unless there are specific contraindications because survival is unequivocally improved with this therapy in this patient group.
It takes more than a single contraction to pump all of the blood out of your heart. Ejection fraction (EF) is a measurement doctors use to calculate the percentage of blood flowing out ...
An ejection fraction below 40 percent is classified as heart failure with a reduced ejection fraction (HFrEF). It occurs when one of your heart’s chambers isn’t able to contract properly. Medications can treat it.
Mildly reduced. An ejection fraction range between 41 and 51 percent for men and between 41 and 53 percent for women is classified as mildly reduced. It could be a sign of heart damage, perhaps from a heart condition or a previous heart attack.
Generally, your left ventricle is the one measured for ejection fraction. It does the heavy lifting in your body, pumping blood to almost all your major organs.
In general, the outlook for an abnormal EF is encouraging. In most cases, with diligent care and medications, you can manage your symptoms and continue living a normal life. Remember to pay attention to your body. Try to eat a balanced, low-fat diet with plenty of leafy green vegetables.
