I am 69 yrs old and have recently been diagnosed with paroxysmal atrial fibrillation (primary), mixed hyperlipidemia, non-rheumatic mitral regurgitation, and non-ischemic cardiomyopathy. Diastolic dysfunction is common in elderly, but all do not develop HF. An LVEF of below 53 percent for women and 52 percent for men is considered low. In heart failure, the EF number can become very low. The British National Formulary is the unrivalled guidance on prescribing, dispensing and administering medicines. Her weight gain during pregnancy was 30 kg. What may I expect for life expectancy and what can I do, other than prescribed medications, to improve my … Hello YES your hypothyroidism also causes congestive heart failure with lowering of ejection fraction , thats good that yyou started synthyroid at 50 microgram , and then increasing the dose , i would also like you to consider digoxin with cardiologist reveiw ,. Ejection fraction decreased. UpToDate, electronic clinical resource tool for physicians and patients that provides information on Adult Primary Care and Internal Medicine, Allergy and Immunology, Cardiovascular Medicine, Emergency Medicine, Endocrinology and Diabetes, Family Medicine, Gastroenterology and Hepatology, Hematology, Infectious Diseases, … There have been few reports of pregnant patients with DCM because the literature recommends against pregnancy if the ejec-tion fraction is <30%. 56 As in all large database analyses, we did not have access to individual … 66-68 Untreated complete AV block may precipitate heart failure during pregnancy. 3.3 Pre-pregnancy counselling 3174 3.3.1 Risk of maternal cardiovascular complications 3174 3.3.2 Risk of obstetric and offspring complications 3174 3.3.3 Pregnancy heart team 3176 3.4 Cardiovascular diagnosis in pregnancy 3176 Heart failure with normal ejection fraction, also known as diastolic heart failure, is a major problem for patients and health-care providers and is a substantial expense to society. First-phase ejection fraction, a possible indicator of heart failure, is a strong predictor of survival in hospitalized COVID-19 patients, according to a new study. Advertising Policy Cleveland Clinic is a … European and American guidelines concur that the lower normal limit for ejection fraction is 55%. The cardiologist will review your health history, perform a physical exam and order diagnostic tests to check your heart function and the severity and extent of your condition. 9. HF is associated with left ventricular dysfunction, and in symptomatic patients with left ventricular ejection fraction (LVEF) ≤ 40%, this condition is called heart failure with reduced ejection fraction (HFrEF) or systolic heart failure. Monitor patients for signs and symptoms of congestive heart failure. Because the expansion in plasma volume is greater than the increase in red blood cell mass, there is a fall in haemoglobin … Book, paperback . Ejection fraction is the amount of blood pumped out of the left ventricle during each heartbeat. Rationale. A normal or hyperdynamic apical impulse suggests good ejection fraction and primary MR. A displaced and sustained apical impulse suggests decreased ejection fraction and chronic and severe MR. Diagnosed with dilated cardiomyopathy, had an echocardiogram and my ejection fraction was 25, had a nuclear stress test and it was 38, which is a more reliable test? Prior echocardiographic studies have described an increase in cardiac dimensions and changes in systolic and diastolic function during normal human pregnancy; however, the studies have been limited by cross-sectional design. WEDNESDAY, Sept. 1 (HealthDay News) -- Patients with heart failure with normal ejection fraction (HFNEF) have a similar peak exercise pulmonary capillary wedge pressure (PCWP) compared to controls but at a lower workload, and the condition is marked by depressed reserve capacity with a variety of issues related to cardiovascular function, according to two studies published in the Sept. 7 … Normal values for ejection fraction (EF) Studies in healthy individuals suggest that the mean ejection fraction is 63% to 69%. It is a rare condition, occurring in 1 in 3000–15 000 pregnancies. CT scan and ultra sound show normal pictures with no stones or sludge. Dofetilide has been shown to adversely affect in utero growth and survival of rats and mice when orally administered during organogenesis at doses of 2 or more mg/kg/day. Systolic function and ejection fraction are normal but end diastolic pressure is elevated because of reduced compliance. In hypertrophic cardiomyopathy ventricular size is normal but ventricular walls (especially interventricular septum) are markedly hypertrophied. Normal ejection fraction. Baseline left ventricular ejection fraction and size were normal and similar to the 12 matched controls (60% ± 6.6% vs. 61.4% ± 6.3%, P = 0.63) or left ventricular end-diastolic dimension (4.6 cm ± 0.2 cm vs. 4.5 cm ± 0.4 cm, P = 0.689). EFs between 50% and 70% are considered normal for the left ventricle. Some patients recover only part of their heart function over a period of six months or longer. This condition is often called irritable uterus (IU). ... Demographic details after delivery in the normal values. An ejection fraction under 50% is regarded as reduced. An EF of 20% is about one-third of the normal ejection fraction. Of greater concern is the widespread classification of patients with heart failure (HF) based on whether EF is preserved (HFpEF) or reduced (HFrEF). A variety of image testing technologies measure ejection fraction. According to the Mayo Clinic guidelines, an ejection fraction above 55% is regarded as normal. In part I, in construction of normal reference ranges of shortening fraction, a total of 606 measurements from 606 fetuses (group 1) were performed for left ventricle shortening fraction and right ventricle shortening fraction . This means that 55% of the total blood in the left ventricle is pumped out with each heartbeat. Baseline left ventricular ejection fraction and size were normal and similar to the 12 matched controls (60% ± 6.6% vs. 61.4% ± 6.3%, P = 0.63) or left ventricular end‐diastolic dimension (4.6 cm ± 0.2 cm vs. 4.5 cm ± 0.4 cm, P = 0.689 Decreases in left ventricular ejection fraction (LVEF) have been reported. Severely below normal (less than 30%): Patients with an ejection fraction this low frequently have significant symptoms due to the body’s inability to compensate for it. Previous right left heart catheterization showed normal coronary arteries and was negative for any shunt. Pre-PPCM echocardiograms were performed between 17.7 weeks of gestation and 13 days post-partum. Methods . 6. In mitral regurgitation, ejection fraction can be excellent, yet part of the left ventricular end-diastolic volume is ejected back into the left atrium via the incompetent mitral valve during ventricular systole. If you exercise 30 - 60 minutes a day, your stress levels can improve. Patients received a median duration of therapy of … Reduced/lower than normal LVEF has various causes, which includes, but is not limited to, cardiomyopathy (heart muscle disease), left ventricular systolic dysfunction (systolic dysfunction, systolic heart failure), and some congenital heart defects/abnormalities. Today, there are still issues when patients with implantable … FH in pregnancy risk factor Ejection Fraction; FH in pregnancy risk factor Ejection Fraction - Book . Cardiac output (CO), also known as heart output denoted by the symbols , or ˙, is a term used in cardiac physiology that describes the volume of blood being pumped by the heart, by the left and right ventricle, per unit time.Cardiac output (CO) is the product of the heart rate (HR), i.e. Our Mission The Point of Care Ultrasound (POCUS) Atlas is collaborative educational platform where we create, share, and curate free ultrasound education material. The ejection fraction is used as a measure of … Usually, patient with a normal or slightly depressed ejection fraction, down to around 40 or so, have a relatively good prognosis and tend to do very well for many many years. I have a HIDA scan ejection fraction for gallbladder of 22%. A normal ejection fraction is more than 55%. The authors describe a series of pediatric patients with frequent ventricular premature complexes (VPC) with or … Even a healthy heart pumps out only about half to two-thirds of the volume of blood in the chamber in one heartbeat. (2.2, 5.2) 12 Embryo-Fetal Toxicity: Exposure to KADCYLA can result in embryo-fetal death or 13 birth defects. TUESDAY, Nov. 11 (HealthDay News) -- The angiotensin-receptor blocker irbesartan does not improve outcomes over placebo in heart failure patients with a normal or near normal left ventricular ejection fraction, according to the results of a study published online Nov. 11 in the New England Journal of Medicine to coincide with the American Heart Association's Scientific Sessions held Nov. 8 … If the ejection fraction (LVEF) is below 35%, it is diagnosed as cardiac failure. Ejection fractions lower than this can mean that the heart is working less well. Withhold treatment for clinically . In mitral regurgitation, ejection fraction can be excellent, yet part of the left ventricular end-diastolic volume is ejected back into the left atrium via the incompetent mitral valve during ventricular systole. Don't get too hung up on a number -- they are just numbers. These parameters are load dependent, so the use of them is limited by the variations in ventricular loading conditions in pregnancy. The primary end-point of cardiovascular death, worsening heart failure (unplanned hospital admission for heart failure or urgent HF visit requiring IV therapy) was significantly reduced (ARR 4.9%, It reflects the pumping capacity of the heart. A low ejection fraction (under 40%) with symptoms usually means systolic heart failure is the primary problem. https://www.ahajournals.org/doi/full/10.1161/circimaging.112.973818 The ejection fraction is used as a measure of the severity of heart failure and helps guide treatment. Adults with chronic heart failure who have reduced ejection fraction are started on low dose angiotensin converting enzyme (ACE) inhibitor and beta blocker medications that are gradually increased until the target or optimal tolerated doses are reached. If yours is 50% or lower, it’s a sign that your heart -- usually your left ventricle -- may not pump out enough blood. When stressed, take 5 slow, deep breaths with your eyes closed, then roll your shoulders forward 5 times, then back 5 times. The POCUS Image Atlas is a collection of rare, exemplary, and perfectl Ejection fraction less than 40%. Measuring Ejection Fraction - Echocardiography Or Nuclear Stress Test? We would call 50% low normal. One woman who had no change in the left ventricular ejection fraction during her first subsequent pregnancy had a substantial decrease in the ejection fraction — … … The ejection fraction is a useful measure of left ventricular performance. Average is reported as being in the low to mid 60s. Of note, the LVEF reference normal value based on SSFP CMR is between 58 and 76% for healthy 40–49 year old individuals 13, and a reduced LVEF, even in the low normal … It is usually measured as a percentage of the amount of blood within the ventricle. The clinical criteria for HFpEF typically include clinical evidence of HF, preserved ejection fraction (EF of ≥40%–50%), and evidence of abnormal diastolic function by noninvasive or invasive approaches. Ejection fraction is a measure (estimate) of the amount of blood pumped during each contraction of the ventricle. The secondary morphologic and functional left ventricular changes induced by chronic hypertension are well known.1,2 Patients with chronic hypertension are exposed to long-lasting pressure overload with enough time to develop changes in left ventricular structure and function.2However, little is known about the changes produced by conditions of acute pressure overload. Plasma volume increases progressively throughout normal pregnancy.2 Most of this 50% increase occurs by 34 weeks’ gestation and is proportional to the birthweight of the baby.

Group health insurance and health benefit plans are insured or administered by … CARDIOVASCULAR ADAPTATIONS DURING NORMAL PREGNANCY. x With interest we have read the article of Bo Chen et al., “Risk Factors for Left Ventricle Enlargement in Children With Frequent Ventricular Premature Complexes”, in the American Journal of Cardiology in June 2020. A. Ejection fraction refers to the volume of blood that's pumped out of the heart's left ventricle each time it contracts. A normal EF can be between 55 and 70. ventricular ejection fraction (LVEF). If you exercise 30 - 60 minutes a day, your stress levels can improve. The left ventricular ejection fraction (LEVF) might seem like an arbitrary measurement, but it can tell us a … 1 It is important to develop uniformity in echocardiographic methodology, gestational age, and equipment and data collection when evaluating serial changes in pregnancy… The BNF is the only drug formulary in the world that is both independent, and has rigorous, accredited content creation processes. Due to this the heart is not able to pump adequate blood to different organs in the body. Diastolic function parameters were assessed using transthoracic echocardiography. The degree of severity does not seem to affect the degree or rate of recovery. Pregnant women with singleton pregnancies carried from 13 weeks to 20 weeks and left ventricular ejection fraction (LVEF) ≥50% were identified. Close watching and the use of certain medications is also advised. A normal ratio is close to 1.0, whereas a ratio of ≤0.25 corresponds to a valve area 25% of normal for that patient, which is consistent with severe AS and is a predictor of symptom onset and adverse outcomes (12,13,21,22,23). Dr said sometimes you see a difference in numbers but rarely this much of a difference. It can also determine ejection fraction — the percentage of blood in the filled left ventricle that is pumped out during a contraction. If the ejection fraction is less than this value, gallbladder dysfunction is suspected. For example, patients with a very low ejection fraction can eventually completely recover from peripartum cardiomyopathy. My ejection fraction is 35%. I have minor pain with some bloating and gas exacerbated by stress and some foods but its not terrible. CMRI showed normal left ventricular structure and function. This means 80% of … Therefore, it can be stated that the normal range for the left ventricle (LV) ejection fraction is 55 to 70 percent. An ejection fraction (EF) is a percentage based on how much blood is pumped out of the heart. Laboratory tests showed increased NT-proBNP level (1944 pg/ml), normal GFR (90 ml/min/1,73m2). Use with caution in patients at … Normal wall motion, ejection fraction (55% to 65%), coronary blood flow, ventricular size and function, and symmetry in contractions of the left ventricle ; Abnormal findings related to. An EF under 40% means the muscle is weakened and you may have heart failure. It never did. 10, 55 However, it is important to note that a recent study validating ICD-9 codes for HF reported ≥90% accuracy. The normal range is 63-77% for males and 55-75% for females. Many doctors consider a normal ejection fraction to be 55% to 75%. ICD-10-CM Diagnosis Code I50.9 [convert to ICD-9-CM] Heart failure, unspecified. A normal heart size is also preferable. pregnancy risk factor Ejection Fraction. Background . Idiopathic DCM accounts for approxi-mately 50% of all cases and 35% are inherited.3 Other forms of DCM are rare, and information on pregnancy in patients with these forms is only found in case reports. Evaluate left ventricular function in all patients 11 prior to and during treatment with KADCYLA. to some infection and this is causing very low blood pressure. For comparison, we identified controls, matched 2:1 on age, race, body mass index, gestational age, … It can also be classified as normal, mildly reduced, moderately reduced and severely reduced without giving a percentage. This is called ejection fraction. It is a measure of the strength of the heartbeat. If the heart is diseased or weak, the ejection fraction decreases. Normal ejection fraction of the heart is in the range of 60% to 80%. It can also be classified as normal, mildly reduced, moderately reduced and severely reduced without giving a percentage. Ejection fraction is a measurement of how much blood your heart pushes out when it beats. After the first trimester, in the majority of mothers, the first sound is louder and has an exaggerated split (resulting from early mitral closure), an ejection systolic flow murmur is detected in 90%, a third heart sound is detected in 80%, and an atrioventricular diastolic flow murmur is detected in 20%. When the ejection fraction is below 20 to 25 percent, it’s considered to be “severely reduced.” However, two people with an ejection fraction of, say, 20 percent, may present quite differently in a clinical setting, even if they are the same age. It pumps oxygen-rich blood up into your body's main artery (aorta) to the rest of the body. Normal ejection fraction of the heart is in the range of 60% to 80%. By mommy101701. So a normal ejection fraction lies somewhere in the range of 55% to 65%. An ejection fraction (EF) is the volumetric fraction (or portion of the total) of fluid (usually blood) ejected from a chamber (usually the heart) with each contraction (or heartbeat).It can refer to the cardiac atrium, ventricle, gall bladder, or leg veins, although if unspecified it usually refers to the left ventricle of the heart. Ejection fraction is reduced and may become progressively worse with time. Even a healthy heart pumps out only about half to two-thirds of the volume of blood in the chamber in one heartbeat. “Normal ejection fraction is between 55-70%,” says Waqar Khan, MD, who’s been providing state-of-the-art cardiology services to the Houston area for over 20 years, and is author of “Be Heart Smart: Understand, Treat, and Prevent Coronary Heart Disease.” According to the American Heart Association, a normal ejection fraction is between 50% and 70%. In this brief review we will focus on drug treatment of HFrEF (Table 1) [1-7]. What Does the Ejection Fraction Tell Us. Your ejection fraction indicates how well your heart is pumping. Low ejection fraction (EF) 32% without regional contractility impairment, severe mitral regurgitation (MR) were revealed. mommy101701 over a year ago. A retrospective cohort study from February 2013 to January 2017 was performed, and 1600 patients were included (136 patients with EF <50% and 1464 patients with EF ≥50%); all patients underwent PCI. In this scenario, ejection fraction can be normal, yet cardiac output is diminished. 1-2 weeks ... Normal price: £39.99; You're saving: £0.00 (0%) There have been few reports of pregnant patients with DCM because the literature recommends against pregnancy if the ejection fraction is <30%. Cardiologists brought Cardwell’s condition under control with medication. The causes of heart failure in women are often linked to high blood pressure, coronary artery disease, valvular disease, and diabetes mellitus. Academic Radiology publishes original reports of clinical and laboratory investigations in diagnostic imaging, the diagnostic use of radioactive isotopes, computed tomography, positron emission tomography, magnetic resonance imaging, ultrasound, digital subtraction angiography, image-guided interventions, and … Objectives The aim of this study was to obtain left ejection fraction (LEF) from fetal heart using four‐dimensional ultrasound (4DUS) and spatio‐temporal image correlation (STIC) in late middle pregnancy. A normal score means that the heart is … Furthermore, the degree of noncompaction was not found to be associated with decreases in ejection fraction or ventricular dilation. Learn about the connection between ejection fraction and heart failure and how to get a low ejection fraction back to normal. A normal ejection fraction runs between 50-70%; a percentage in the 40s is considered below normal, and under 40% is considered a low EF and is possibly indicative of a variety of heart issues. Pregnancy-induced Whether it’s a cardiologist or your primary care physician, talk to a doctor … Heart failure with normal ejection fraction (HNEF) – HFpEF: Signs and symptoms of heart failure with ejection fraction > 50%, and diastolic dysfunction constitutes the group of heart failure with normal ejection fraction (HNEF). Ejection Fraction or E.F. measures the percentage of blood volume expelled by the left ventricle with each beat. HNEF contributes to about 50% of heart failure. well your left ventricle (or right ventricle) pumps blood with each heart beat. For several months, she also wore a battery-powered defibrillator vest, which would shock her heart into normal rhythm in the event it stopped beating. Diagnosis Symptoms and signs … In addition, major cardiovascular events (heart transplantation, LV assist device, or death) occurred almost exclusively in women with an ejection fraction of <30%. I could look at an echo and call it 55% and the doctor next to me could say 50% or 60%. EF is erroneously assumed to be a measure of myocardial contractility. ICD /LOE EJECTION FRACTION AND PREGNANCY . In some cases the ejection fraction can be normal, but due to the increased pressures inside the heart and lungs, the patient can have heart failure. MPRI borderline normal 1.8 November 2016 (10-year follow-up) Emergency Department visit for heart failure and initial diagnosis for heart failure with preserved ejection fraction As a percentage it does not tell you the actual volume pumped per heartbeat. A normal ejection fraction ranges from 50% to 70%. Cardiac Rehabilitation. A presentation from the Echocardiography ePosters session at ESC CONGRESS 2020 - The Digital Experience Mean (±SD) Left Ventricular Ejection Fraction in 44 Women at the Time of the Diagnosis of Peripartum Cardiomyopathy (Index Pregnancy), at Postpartum Follow-up, during the First Subsequent Pregnancy, and at the Last Follow-up a Mean of 72 Months after the First Subsequent Pregnancy. In this scenario, ejection fraction can be normal, yet cardiac output is diminished. the number of heartbeats per minute (bpm), … Your prognosis depends on your heart function. Confirm normal LVEF before starting TYKERB and continue evaluations during treatment. A normal ejection fraction is about 50% to 75%, according to the American Heart Association. 56 ECG changes in a normal pregnancy … Heart ventricles extensively weakened by heart attacks or cardiomyopathy will have low ejection … Pre-eclampsia was identified from medical records. Reduced ejection fraction is defined as ejection fraction <55%. The parameters of myocardial systolic function, including ejection fraction (EF), shortening fraction and tissue Doppler velocity, have been variously described as decreased , increased or remained constant . Idiopathic DCM accounts for approximately 50% of all cases and 35% are inherited.3 Other forms of DCM are rare, and information on pregnancy in patients with these forms is only found in case reports. (5.1) TYKERB has been associated with hepatotoxicity. Ab-normal strain can be detected, however, suggesting that strain imaging could represent a screening method in populations at With regards 3D volumetric assessment and 3D-derived ejection fraction, the BSE stresses that reference intervals for 2D-derived ejection fraction do not apply to 3D results: for example, an ejection fraction of 56% derived using 3D software is not necessarily normal, and comparison with vendor-specific … Therefore, if you start with with a cup of blood and push out 1/2 cup per beat, the ejection fraction is 50%. Monitor liver function tests before initiation of treatment, every 4 to 6 weeks during treatment, and as clinically indicated. While no heart pumps every drop of blood back to the body, those with heart failure and other cardiovascular issues may have an EF percentage that is below normal or dangerously low. Learn more . Patients with ejection fraction below 35% … A low ejection fraction is often an indication of heart failure. Left ventricular systolic dysfunction - - Symptomatic due to drop in ejection fraction responsive to intervention Refractory or poorly controlled heart failure due to drop in ejection fraction; intervention such as ventricular assist device, intravenous vasopressor support, or heart transplant … significant decrease in left ventricular function. You can have a normal ejection fraction measurement and still have heart failure (called HFpEF or heart failure with preserved ejection fraction). The authors found that COVID-19 patients with a first-phase ejection fraction of less than 25% had a nearly five-fold higher risk of death than those with an ejection fraction of 25% or higher. These changes are not directly reflected by parameters traditionally considered to describe systolic function, such as ejection fraction and longitudinal deformation. Mitchell was rushed to Michigan Medicine, known for its highly skilled team of experts in high-risk pregnancies and cardio-obstetrics. Heart failure with normal ejection fraction; Heart failure with preserved ejection fraction [HFpEF] Code Also. Ejection fraction Ejection fraction, sometimes called left ventricular ejection fraction, measures the percentage of blood that the heart pumps out of the left ventricle with each heart contraction. To evaluate whether a reduced left ventricular ejection fraction (LVEF) is a risk factor in patients after percutaneous coronary intervention (PCI). ... rather than left ventricular contraction, and is characterised by normal or preserved left ventricular ejection fraction with … EF is how much blood the left ventricle pumps out with each contraction. 1.5.2 For people who have heart failure with reduced ejection fraction and chronic kidney disease with an eGFR below 30 ml/min/1.73 m 2, ... Contraception and pregnancy. A normal heart’s ejection fraction may be between 50 and 70 percent. You can have a normal ejection fraction measurement and still have heart failure (called HFpEF or heart failure with preserved ejection fraction). Abnormal wall motion (akinesia or dyskinesia) Severely below normal (less than 30%): Patients with an ejection fraction this low frequently have significant symptoms due to the body’s inability to compensate for it. The mean number of measurements per week was 22.4 ranging from 15 to … We conclude that women who develop PPCM have normal left ventricular ejection fraction during gestation preceding PPCM, indicating that the disease develops acutely in the peripartum period. (A normal “ejection fraction” ranges from 55% to 65%.) Contrary to what many people believe, a normal ejection fraction is not 100%. When we quote ejection fraction we usually have the caveat +/- 5% after it. Stay active: Exercise is a great way to relieve stress.Your body releases endorphins during exercise, which can help you feel calm. An echocardiogram revealed a low ejection fraction — the percentage of blood moving from the heart each time it contracts. 1 Mean BP gradually falls during pregnancy… Some women develop frequent, regular contractions that don’t produce any change in the cervix. The long-standing emphasis on ejection fraction (EF) is misguided. Heart failure, in particular, is diagnosed and evaluated through a changing ejection fraction. increased thirst (drinking more than normal) ... Pregnancy. 66 Pregnancy may precipitate SRV failure (3% to 8% of pregnancies) and arrhythmias (2% to 10%). A normal LVEF reading for adults over 20 years of age is 53 to 73 percent. Pre‐PPCM echocardiograms were performed between 17.7 weeks of gestation and 13 days post‐partum. A normal ejection fraction is 55– 60%. (5.2) • Prolonged QT intervals and Torsade de Pointes have been observed. Heart pumping function is reduced, with an ejection fraction (EF) less than 45% (typically measured by an echocardiogram). 5. ... beauty, health, pregnancy … The normal ejection fraction value is 55 – 65%. It can also be classified as normal, mildly reduced, moderately reduced and severely reduced without giving a percentage. Jan 22, 2016. The ejection fraction is a measure of the amount of blood that is pumped out (ejected) from the heart each time the left ventricle contracts. Ejection fraction measures the amount of blood pumped out of your heart’s lower chambers, or ventricles. Quantitate cardiac output by calculating global or regional ejection fraction ; Potential diagnosis Normal findings. A normal ejection fraction number is about 60%. Echocardiography is also used to determine the left ventricular ejection fraction, an objective measure of the heart's pumping ability ... the value of supplemental coenzyme Q 10 and/or D-ribose in the treatment of congestive heart failure in patients with normal left ventricular ejection fraction .
