Ejection fraction (EF) is a measurement, expressed as a percentage, of how much blood the left ventricle pumps out with each contraction. An ejection fraction of 60 percent means that 60 percent of the total amount of blood in the left ventricle is pushed out with each heartbeat. A normal heart’s ejection . See moreAn EF from 41 to 49 percent might be considered too low. It does not always indicate that a person is developing heart failure, but it could indicate damage, perhaps from a previous heart attack. An ejection fraction measurement under 40 percent might be . See moreYour health care professional might recommend one or more of these tests to measure your ejection fraction: 1. Echocardiogram(or “echo”) - the most widely used test 2. . See moreYour health care professional might mention one of these two EF-related scenarios: 1. Preserved ejection fraction (HFpEF)– also . See more

Ejection fraction typically refers to the left side of the heart. It shows how much oxygen-rich blood is pumped out of the left ventricle to most of the body’s organs with each . A normal ejection fraction range is between 52 and 72 percent for men and between 54 and 74 percent for women. An ejection fraction that’s higher or lower may be a sign of heart failure or an.

For an ejection fraction in the range of 50% to 55%, most of the commonly used tests, if carefully performed, are accurate within a few percentage points (e.g. 55% plus or minus 3%). With respect to the lower limit of “normal” .The current ACCF/AHA guidelines classify patients with a left ventricular ejection fraction (LVEF) of ≥50% as having a preserved ejection fraction (4), and previous studies have found that .European Society of Cardiology and American Society of Echocardiography guidelines report normal LVEF as >50% and >55%, respectively (2, 3) and clinical HF trials have defined left . A left ventricle (LV) ejection fraction of about 50% to 70% is categorized as normal. A mildly reduced LV ejection fraction is usually between 41% and 49%. A reduced LV ejection .

In most cases, ejection fraction refers to the percentage of blood that's pumped out of the left ventricle with each heartbeat. For example, an ejection fraction of 50% means that 50% of the blood from the left ventricle is .

The British Society of Echocardiography recently updated their normal reference intervals for assessment of cardiac dimensions and function. 1 They describe four categories of left ventricular function and a ‘normal’ LVEF is defined as ≥55%. Left ventricular ejection fraction (LVEF) is the central measure of left ventricular systolic function. LVEF is the fraction of chamber volume ejected in systole (stroke volume) in relation to the volume of the blood in the ventricle at . The ejection fraction is usually measured only in the left ventricle. The left ventricle is the heart's main pumping chamber. It pumps oxygen-rich blood up into the body's main artery, called the aorta. The authors did not find a J-shaped relationship between LVEF and noncardiovascular or all-cause death, which contrasts with previous studies 5 that found increased risk of death with an LVEF >65% for both those with and .

Left Ventricular Ejection Fraction (LVEF) . If your heart is healthy, your EF should be between 55% and 70%. Below 50% is a sign of a problem. Below 40% could indicate heart failure. (Photo .

A cutoff value of 55% had sensitivity of 90.9% and specificity of 97.7%. Logistic regression analysis indicated that LVEF ≤55% and ischemic etiology were strong predictors of progression from HFpEF to HFmrEF (odds ratio [OR] 435, 95% confidence interval [CI] 52.65-10,614, P<0.0001 and OR 10.9, 95% CI 2.60-74.80, P=0.0007, respectively).

Left ventricular ejection fraction (LVEF) is the central measure of left ventricular systolic function. LVEF is the fraction of chamber volume ejected in systole (stroke volume) in relation to the volume of the blood in the ventricle at the end of diastole (end-diastolic volume). Stroke volume (SV) is calculated as the difference between end-diastolic volume (EDV) and .

It is the only method of measuring LVEF that has potential risks and complications. Interpreting Results . . interpreting LVEF results in terms of evaluating heart health based on the fact the left ventricle typically ejects 55% or more of its blood volume per beat. Normal: 50% to 70%: Below normal: 41% to 49%:Hjertesvigt med bevaret LVEF (HFpEF) Andelen af patienter hvor diagnosen Hjertesvigt med bevaret LVEF (Heart Failure with preserved Ejection Fraction, HFpEF) der tidligere kaldtes diastolisk hjertesvigt, kan stilles varierer efter diagnostiske kriterier. De seneste definitioner definerer denne tilstand som hjertesvigt med LVEF > 50 %

Normal EF is in the range of 55% to 70%. As the percentage falls, it tells the doctor that the heart failure is getting worse. In general, if the EF falls below 30%, it's relatively severe.

The characteristics of participants with an LVEF of 50% to 55% in comparison with groups with an LVEF <50% and an LVEF >55% are presented in Table 1. Participants in whom LVEF assessment was unavailable had a greater burden of CVD risk factors but a prevalence of MI similar to that of participants with available echocardiograms ( Online Table 2 ).

The goal of this study was to identify the adverse outcomes of borderline (50% to 55%) left ventricular ejection fraction (LVEF). In an analysis of 10,270 Framingham Heart Study participants, researchers found that an LVEF of 50% to 55% was associated with an increased risk of heart failure (HF) or death (HR, 1.37) and incident heart failure (HR, 2.15).We would like to show you a description here but the site won’t allow us.Die linksventrikuläre Ejektionsfraktion, kurz LVEF, ist ein Parameter, der in der Regel im Rahmen der Echokardiographie erhoben wird, aber auch durch andere bildgebende Verfahren ermittelt werden kann. Er gibt Aufschluss über das Blutvolumen, das während der Systole aus dem linken Herzventrikel getrieben wird und ist daher ein direktes Maß für die linksventrikuläre Funktion.

eft ventricular ejection fraction (LVEF)1 has per-sisted as the primary measure of left ventricular systolic function despite flaws in this approach. Patients with heart failure are relieved when the LVEF is reported as normal, and clinicians may use the report of a depressed LVEF to persuade patients of the need for treatment. 2. Be a heart detective. Put this on your doctor’s to-do list, too. By identifying and treating the underlying causes of low ejection fraction, you take major steps toward improving your quality .The ejection fraction (EF) is the amount of blood your heart pumps (or ejects) with each heartbeat and is a useful way of measuring LVSD. A normal EF is about 55-65 per cent. It’s important to understand that “normal” is not 100 per cent. .

Good news! Many people with a low ejection fraction (or EF) have successfully improved it.. Better heart failure management can lead to a better ejection fraction. By managing your heart failure carefully and following your .

Background: Among patients with heart failure (HF) with reduced ejection fraction (EF), improvements in left ventricular EF (LVEF) are associated with better outcomes and remain an important treatment goal. Patient factors .Objectives: This study sought to examine the association of a borderline left ventricular ejection fraction (LVEF) of 50% to 55% with cardiovascular morbidity and mortality in a community-based cohort. Background: Guidelines stipulate a LVEF >55% as normal, but the optimal threshold, if any, remains uncertain. The prognosis of a "borderline" LVEF, 50% to .

A U-shaped relationship was observed between quantified LVEF and cardiovascular events risk with the nadir at the LVEF of 55–64%. As compared to moderate LVEF (55–64%), both low (40–54%) and .

Introduction. Detection of depressed left ventricular function may improve prevention and treatment of progression to symptomatic heart failure ().In adults over 50 years of age, the presence of even a mildly abnormal LVEF (LVEF≤55%) is associated with an approximately three-fold increased risk of developing heart failure and a two-fold increased risk of mortality . LVEF >55% is usually normal, and in patients with LVEF 50-54% in a borderline range which is low normal in some patients and reduced in others depending upon other independent markers of LV dysfunction, e.g., symptoms, global longitudinal strain (GLS) and elevation of cardiac biomarkers. Given that the variability of LVEF measurement is at .من دوسال پیش اکو انجام دادم55 =lvef بود.الان دوباره اکو انجام دادم و این عدد شده 50.. بیشتر اوقات تپش قلب شدید دارم. قرص پروپرانول مصرف میکنم تا بهترشم گاهی 2 یا 3 تا قرص باهم میخورم تا تپش قلبم آروم . Left ventricular ejection fraction (LVEF) is the central measure of left ventricular systolic function. LVEF is the fraction of chamber volume ejected in systole (stroke volume) in relation to the volume of the blood in the ventricle at the end of diastole (end-diastolic volume). Stroke volume (SV) .

有研究显示，lvef可作为患者死亡风险的评估指标，lvef越低，表明心功能越差，左室功能受损越严重，其死亡风险也就越高： 当患者的射血分数降低至40%以下时，表明患者的心脏收缩功能受到较大影响，医生常常会结合症状体征及辅助检查确诊患者为射血分数 .Results: During follow-up (median 7.9 years), HF developed in 355 participants, and 1,070 died. Among participants with an LVEF of 50% to 55% (prevalence 3.5%), rates of the composite outcome and HF were 0.24 and 0.13 per 10 years of follow-up, respectively, versus 0.16 and 0.05 in participants having a normal LVEF.The strongest predictor of outcome after surgery for chronic mitral regurgitation is the pre-operative left ventricular ejection fraction [29,30].Despite the fact that the presence of mitral regurgitation means left ventricular ejection fraction underestimates the degree of left ventricular dysfunction, pre-operative ejection fraction has been shown to be a significant predictor of post .

Women with normal LVEF (55–65%) had a significantly higher rate of mortality compared to women with high LVEF (>65%), and an LVEF of 58% was determined to be the optimal cut-off point for predicting mortality. There is an increasing awareness of sex specific presentation of ischemic heart disease (IHD).
