Ejection fraction how is it done?
Left heart EF, known as left ventricular ejection fraction (LVEF), is calculated by dividing the volume of blood pumped from the left ventricle per beat (systolic volume) by the volume of blood collected in the left ventricle at the end of the diastolic filling phase (volume ...
How to calculate the ejection fraction?
The ejection fraction is calculated with the formula: FE = 100 * (VTD - VTS) / VTD. The ejection fraction can be estimated with various diagnostic methods, both invasive and non-invasive. However, it is usually determined, in a non-invasive and easily repeatable way, by means of echocardiography.
What is meant by an ejection fraction?
Ejection fraction (or FE) is a medical measurement that indicates the contractile capacity of one of the heart chambers by measuring the amount of blood expelled from the heart each time it contracts, expressed as a percentage, 1 cardiac function index.
What does Fe mean in cardiology?
The ejection fraction (FE) represents the most used parameter in cardiology for the evaluation of the systolic function of the left ventricle. Much of the success of this parameter is due to the prognostic significance demonstrated in patients with myocardial infarction and chronic heart failure 1-4.
When does heart failure lead to death?
The adverse outcome is death within 30 days of the date of hospitalization from congestive heart failure.

What can cause heart failure?
Heart failure typically develops as a result of heart injury, for example as a result of myocardial infarction, overexertion of the heart due to hypertension that has not been treated for several years, or as a result of valvular dysfunction.
How long can you live after heart failure?
This has a huge impact on survival - the expert points out - Just think that for a patient with heart failure undergoing hospitalization means having a life expectancy of 2,4 years, while with 2 hospitalizations the prognosis is halved to 1,2. years".
How much does it have to be Fe?
In people with a normal and healthy heart, the ejection fraction is 55% or higher. This means that 55% of the blood that fills the left ventricle is pumped around the body with each contraction.
What is dilated cardiomyopathy?
Dilated cardiomyopathy is a disease that affects the heart muscle and impairs the heart's ability to efficiently pump blood to the rest of the body.
How much should the heart's FE be?
In a healthy heart, the ejection fraction is approximately 60%. A value below 40% indicates that the heart is unable to pump an adequate amount of blood throughout the body.
What is first degree diastolic dysfunction?
First degree diastolic dysfunction: inversion of the E / A ratio. It is the mildest form of diastolic dysfunction and is also often referred to as "impaired ventricular relaxation". Patients are asymptomatic.
How is cardiac output calculated?
It is calculated from measurements of the volume of the ventricles obtained with echocardiography, subtracting the volume of blood that remains in the ventricle after systole (called the end-systole volume) from the volume of blood present in the ventricle just before the systole (end-diastolic volume).
What is seen with an echocardiogram?
Echocardiography allows to obtain information on the contractility of the heart, on the morphology of its valves and on the flow of blood in its cavities, both at rest and after physical exercise or taking a drug.
What does branch block mean?
Branch block is a type of conduction block that involves a partial or complete interruption of the flow of electrical impulses through the right or left branch. (See also Overview of Heart Rhythm Changes and Overview of Heart Block.)
What does systolic function mean?
Phase of the cardiac cycle corresponds to the time when the atrial and ventricular myocardium contract (systole). Atrial contraction completes the delivery of blood into the ventricle, while ventricular systole allows blood to enter and progress into the peripheral arterial circulation.
When does the left ventricle contract?
Under normal conditions, the ventricle stretches during diastole, filling with oxygenated blood from the left atrium; during systole, on the other hand, it contracts and pushes the blood into the aorta with a pressure that exceeds that of the aorta itself.
Why does the heart expand?
Its appearance may be due to different pathological conditions, which may not directly affect the heart. In fact, among the main triggering causes, in addition to heart attack, cardiac arrhythmias, dilated cardiomyopathy, etc., hypertension, anemia and hemochromatosis also appear.
How long do you live with dilated cardiomyopathy?
based on the date of the first diagnosis. Today, 10-year heart transplant-free survival exceeds 85% of cases.
How is cardiomyopathy treated?
Treatment. A heart with dilated cardiomyopathy cannot heal. However, thanks to a combination of drugs - and the possible implantation of some cardiac devices, such as a pacemaker or cardioverter defibrillator - it is possible to partially improve the symptoms.
What are the symptoms of heart failure?Heart failure is accompanied by characteristic symptoms:
- dyspnea, i.e. difficulty in breathing (shortness of breath);
- orthopnea difficulty breathing when lying down;
- frequent cough, especially if lying down;
- swelling (edema) of the feet, ankles and legs;
- general weakness, fatigue or tiredness;
What does mild heart failure mean?
Heart failure is defined as a disorder in which the heart is no longer able to meet the body's needs, causing a reduction in blood flow, accumulation (congestion) of blood in the veins and lungs and / or other changes that can further weaken or stiffen the ...
When the heart can't take it?
Heart failure (IC) or more commonly heart failure (HF), is the condition in which there is ventricular dysfunction in which the heart cannot pump enough blood to meet the body's demands.
How to live with heart failure?RULES FOR LIVING WITH HEART FAILURE
- Stop smoking;
- Keep blood pressure, cholesterol and blood sugar values under control in case of diabetes;
- Follow a controlled diet, reduce salt intake and avoid being overweight;
What to do after heart failure?
limit the intake of alcoholic beverages; control weight and fluid intake; start an aerobic exercise program initially under medical supervision (rehabilitation program) and subsequently self-managed.
What does heart failure mean in the advanced class?
Class III: Moderate to severe heart failure. Minimal physical activity (such as walking around the house or climbing half a flight of stairs) causes breathlessness or fatigue. Class IV: Severe heart failure. Exhaustion, dyspnea or fatigue also present at rest (sitting or lying in bed).
