Systolic Heart Failure Ejection Fraction

Don't Miss

Four Pillars Of Disease

Medical School – Heart Failure with Reduced Ejection Fraction (Systolic Heart Failure)

The neurohormonal model of heart failure is key to understanding the efficacy of disease-modifying medical therapy and is summarised in . More recent evidence for the significant benefits related to reducing heart failure admissions associated with SGLT2i expands our understanding of the pathophysiology of heart failure and cements these agents as fundamental keystones in the management of HFrEF.

Beta-blockers indicated in HFrEF

The use of B may worsen acute heart failure and so clinical assessment is required to ensure that the patient with HFrEF is not decompensated at the time of B initiation. Patients may often feel less well for 4872 hours following initiation of B or dose escalation and they should be warned of this to improve compliance with life-saving therapy. Where patients with HFrEF have decompensated on stable doses of B, they should be continued at the same dose, while managing the decompensation. Dose titration should be to the maximum tolerated with a target resting heart rate of 6070 bpm in sinus rhythm. Use of B in patients with HFrEF with AF is recommended, although prognostic benefits are less well proven and aggressive rate control does not appear to provide any significant benefits when compared with more modest rate control. Some patients may not tolerate B at higher doses and where the heart rate remains above 70 bpm then the If channel blocker, Ivabradine, may be used to slow the sinus rate and improve symptoms and mortality.

How Will I Know If My Ejection Fraction Is Improving

If you have a low ejection fraction, youll have frequent appointments with your healthcare provider to monitor it. Its essential to go to all appointments, even if you dont feel sick.

If your symptoms are fading, it may be a sign that ejection fraction is improving. But its also possible for symptoms to worsen or for new ones to appear. These issues may indicate a worsening ejection fraction.

Contact your healthcare provider immediately do not wait until your next appointment if you experience:

  • Difficulty breathing, especially when lying down.
  • A heartbeat that feels unusually fast.
  • Loss of appetite or vomiting.
  • Sudden weight change, which could be a sign of fluid retention.
  • Unexplained weakness or dizziness.

Get The Right Amount Of Physical Activity

Exercise helps most people with HF, and some patients who follow an exercise plan may see improvements in their EF. Research shows that being active can help people living with heart failure by reducing symptoms, improving mood and even increasing the hearts ability to pump blood. If your heart failure is stable, and you have your doctors okay, do what moves you.

Here are some exercise tips to keep in mind.

In general, a diagnosis of heart failure is serious, since it can cause life-threatening arrhythmias and organ failure.

Taking medications as prescribed, monitoring fluid status, and close follow-up with a healthcare provider can help people with heart failure stay out of the hospital and improve quality of life.

Advanced treatments and heart transplant are also options for those with very severe heart failure.

Invasive Hemodynamic Measurements And Outcome

Numerous invasive hemodynamic measurements were associated with the primary outcome, hospitalization for heart failure and/or death for cardiac reason, in the univariate Cox regression analysis and are displayed in detail in Table 3. In brief, in the univariate analysis invasively measured sPAP displayed a HR per 1-SD of 1.68 , PAWP a HR of 1.56 , PVR a HR of 1.52 , and TPG a HR of 1.52 . These effects remained virtually unchanged after adjustment for potential confounders. Detailed results of the Cox regression analysis are shown in Table 3. Kaplan Meier analysis demonstrated a significant increase of the primary endpoint, in patients with increased sPAP , and increased PAWP . In detail, freedom from the primary outcome in patients with increased sPAP was present in 51% vs. 83% after 1 year and in patients with increased PAWP in 52% vs. 81% after 1 year . The AUC was 0.75 for sPAP, and 0.68 for PAWP with corresponding C-statistics of 0.72 and 0.63, respectively.

What Is The Difference Between Heart Failure With Preserved And Reduced Ejection Fraction

Heart failure with reduced ejection fraction is also known as systolic heart failure. It also affects the left ventricle but in different ways.

In HFrEF, the left ventricle is too weak rather than too stiff. It cant contract properly. It may fill with enough blood during the cardiac cycles diastole phase, but it cant pump that blood with enough force during the systole phase, so the amount of blood ejected is reduced.

Ejection fraction is a measurement that compares the amount of blood that fills your ventricle to the amount of blood that your ventricle pumps out with each contraction.

A normal ejection fraction is 55 to 70 percent . If your ejection fraction is below 50 percent, you may have HFrEF.

If you have HFpEF, you may actually have a normal ejection fraction. Thats because theres less blood coming into the stiffened left ventricle, but your heart is still able to pump that blood back out of the ventricle.

Though the proportion of blood going into the proportion going out is normal, your body still isnt getting enough oxygenated blood with each cardiac cycle.

Your doctor wont be able to tell whether you have HFpEF and HFrEF based on your symptoms alone.

To measure your ejection fraction and diagnose the type of heart failure you have, your doctor may order tests such as:

The treatment options for HFpEF are limited.

Your doctor may prescribe diuretics to limit fluid build-up in your tissues.

For example, they may prescribe medication to:

Adjunctive Therapies And The Impact Of Comorbidity

Comorbidities are common in a patient with HFrEF and their management should be optimised alongside initial heart failure therapy.

  • Cardioselective B are safe to prescribe in all patients with chronic obstructive pulmonary disease.

  • ACEi are generally recommended where renal dysfunction complicates HFrEF. Advice from a renal physician in cases of significant chronic kidney disease is often helpful. Where ACEi cannot be used due to concerns over renal dysfunction, then the combination of a nitrate and hydralazine has some evidence for benefit.

  • A direct oral anticoagulant will generally be recommended in all cases of HFrEF complicated by AF. Restoration of sinus rhythm may confer benefit in HFrEF but this remains a controversial area. Cardioversion, often facilitated by amiodarone, may be considered to improve symptoms. Dronedarone and flecainide should be avoided. Catheter ablation may have a role in improving prognosis but data remain conflicted and careful patient selection by an appropriate multidisciplinary team review is recommended.

  • Digoxin can be useful in addition to B to improve rate control in AF particularly in less ambulant patients. It can also be used in those who remain symptomatic despite OMT where even 62.5 g once daily can give some symptomatic relief and is associated with a reduction in hospitalisation.

What Is Ejection Fraction

Treatment of Heart Failure with Reduced Ejection Fraction (HFrEF) or Systolic Heart Failure

Systolic heart failure is also called heart failure with reduced ejection fraction .

Ejection fraction is a measurement that represents the percentage of blood the left ventricle pumps out with every contraction. Its a sign of how well your heart is pumping blood.

The normal, healthy range for EF measurement is 55% to 70%. An EF under 40% may indicate systolic heart failure.

What Is Systolic Heart Failure

Systolic heart failure is a condition in which the left ventricle of your heart is weak.

Your left ventricle is the largest and strongest chamber of your heart. Its responsible for pumping oxygen-rich blood from your lungs to the rest of your body.

When the left ventricle is weak it can cause fluid to build up in your lungs, resulting in shortness of breath or fatigue. It can also cause swelling in your body, including your belly, feet and legs.

Systolic heart failure can result from coronary artery disease, high blood pressure, previous heart attack, abnormal heart rhythm, alcohol use disorder and many other causes.

Its important to recognize symptoms of heart failure and identify the cause. There are many treatments available that can improve your heart function, quality of life and how long you live.

What Is Low Ejection Fraction

Ejection fraction measures how well your heart is functioning. Its expressed as a percentage and indicates how much blood your heart is pumping out with each contraction.

For example, an ejection fraction of 60% means your heart is pumping 60% of your blood out of your left ventricle every time your heart beats. Generally, a normal range for ejection fraction is between 55% and 70%.

Low ejection fraction, sometimes called low EF, is when your ejection fraction falls below the normal range. It means your heart isnt functioning as well as it should. Your doctor will want to thoroughly check you for a heart condition to find the cause.

A low number can be serious. If your ejection fraction is 35% or below, youre at high risk of developing a dangerous arrythmia or even heart failure.

Advanced Therapies And Palliative Care

Myocardial Injury and Cardiac Reserve in Patients With Heart Failure ...

Patients deteriorating despite optimal medical and device therapy may follow one of two trajectories. A small group of patients may be eligible for mechanical circulatory support, according to INTERMACS classification, and consideration of cardiac transplantation. Early discussionĀ±referral for specialist assessment at a transplant centre in an appropriate patient should always be considered. Prompts for referral include frequent hospitalisation, worsening symptoms, reduced ability to tolerate medical therapy and requirement for inotropic support. Many patients with HFrEF are elderly or will have comorbidity which precludes consideration of cardiac transplantation. These patients require good palliative care, hand-in-hand with their ongoing supported self-management. Experience shows that involvement of these services earlier in the care pathway can be highly beneficial. Recognising the deteriorating patient and developing an appropriate advanced care plan should be the natural progression of care for all members of the wider MDT.

Low Ejection Fraction Causes

An ejection fraction that falls lower than the normal range is often a sign of an underlying heart disease. Many different heart and vascular conditions can lead to low ejection fraction, such as:

  • Cardiomyopathy, which causes your heart muscle to become enlarged, thick or stiff
  • Coronary artery disease, where plaque builds up in the two main arteries that supply blood to your heart and blocks blood flow
  • Heart attack, when blood flow to your heart muscle became blocked and damaged
  • Heart valve disease, when one or more of your heart valves dont open and close the way they should
  • Systolic heart failure, when your hearts left ventricle cant pump blood forcefully enough

What Is The Outlook For People With Systolic Heart Failure

Heart failure is a chronic serious condition that can shorten your lifespan. Prognosis depends on several factors, including:

  • How advanced heart disease is.
  • Overall health and other health conditions.
  • Response to treatments.
  • Sudden and severe shortness of breath.

What else can I ask my healthcare provider?

Consider asking your healthcare provider:

  • What is causing systolic heart failure?
  • Is it affecting other organs?
  • What is my ejection fraction?
  • How can I improve my condition?
  • What lifestyle changes or medications might help me?
  • What should I avoid?
  • When should we test my ejection fraction again?

A note from Cleveland Clinic

Systolic heart failure is a serious, chronic condition that occurs when the left ventricle cant pump blood efficiently. Talk to your healthcare provider if you have symptoms of heart failure. Treatment for any underlying causes and good lifestyle choices can ease symptoms and help you live a longer, fuller life.

Using Ejection Fraction In Diagnosis

When examined using an echocardiogram, a significant number of patients with heart failure are revealed to have normal ventricular ejection fraction. This condition was previously called diastolic heart failure its now referred to as heart failure with preserved ejection fraction.

Your doctor may mention one of these two EF-related scenarios:

  • Preserved ejection fraction also referred to as diastolic heart failure. The heart muscle contracts normally but the ventricles do not relax as they should during ventricular filling .
  • Reduced ejection fraction also referred to as systolic heart failure. The heart muscle does not contract effectively, and therefore less oxygen-rich blood is pumped out to the body.
  • Heart Failure With Reduced Ejection Fraction

    Also called systolic heart failure, heart failure with reduced ejection fraction is the most common type of heart failure. It occurs when the left ventricle, the hearts main pumping chamber, weakens and cant pump blood effectively. This condition is also often called dilated cardiomyopathy.

    Although people of all ages can develop this type of heart failure, it occurs most frequently in people who are middle-aged and older. The most common cause is a previous heart attack.

    Other causes include high blood pressure, heart inflammation due to an infection, the use of certain chemotherapy drugs, and excessive alcohol intake. Heart failure with reduced ejection fraction may also run in families. Sometimes the cause cannot be identified.

    Deterrence And Patient Education

    Emphasizing diet and medical compliance to patients with HF is important as one of the most common causes of HF readmission is the failure to comply either with diet or medications. A single session intervention could be beneficial as a randomized control trial of 605 patients with HF found that the incidence of all-cause hospitalization or mortality was not significantly reduced in patients receiving multisession self-care training compared to those receiving a single-session intervention.

    How Can Hfpef Affect Me

    With preserved ejection fraction , contractions pump a large portion of blood out to your body. But the left ventricle holds a lower volume of blood. This is often because thick or stiff heart tissue effectively shrinks ventricle size. When this happens, the amount of blood pumped out to the body isnt enough to meet its needs.

    You may be at risk for heart failure with preserved ejection fraction if you have:

    Ejection Fraction From 55% To 70%

    When the pumping ability of the heart is normal, between 55% and 70% of the blood is pushed out into the body by the left ventricle each time the heart contracts. Just because heart function appears normal based on the ejection fraction, it is still possible to have heart failure. This is called heart failure with preserved ejection fraction or diastolic heart failure. This indicates that the left ventricle is still pumping normally but it can no longer relax properly or fill completely with blood because the muscle has become stiff. In addition to the EF measurements, the heart valves and heart muscle should be evaluated for stiffness to determine the severity of heart failure.3
