Left ventricular ejection fraction (LVEF) is one of the most commonly reported measures of left ventricular (LV) systolic function. It is the ratio of blood ejected during systole (stroke volume) to blood in the ventricle at the end of diastole (end-diastolic volume).

What does LVEF measure?

Left ventricular ejection fraction (LVEF) is one of the most commonly reported measures of left ventricular (LV) systolic function. It is the ratio of blood ejected during systole (stroke volume) to blood in the ventricle at the end of diastole (end-diastolic volume).

Is LVEF increased?

LVEF increased significantly in both two groups (group 1: 26.2 ± 4.8% to 32.4 ± 8.5%; p < 0.001; group 2: 38.2 ± 2.5% to 44.4 ± 9.6%; p < 0.001).

What is a healthy LVEF?

A normal left ventricular ejection fraction (LVEF) ranges from 55% to 70%. An LVEF of 65%, for example, means that 65% of the total amount of blood in the left ventricle is pumped out with each heartbeat.

What does LVEF 30 mean?

Normal = LVEF 50% to 70% (midpoint 60%) Mild dysfunction = LVEF 40% to 49% (midpoint 45%) Moderate dysfunction = LVEF 30% to 39% (midpoint 35%) Severe dysfunction = LVEF less than 30%

What does 25 percent heart function mean?

25% is not a bit weak, it is severe lv dysfunction. And yes it is risky …

What does LVEF 40 mean?

An LVEF below 40 percent is heart failure with reduced ejection fraction (HFrEF). It can also be due to cardiomyopathy, which is when your heart muscle weakens, making your heart less effective at pumping blood to the rest of your body.

What does LVEF 45 mean?

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).

How long can you live with 30% ejection fraction?

About 30% will survive for 10 years.

How long can a person live with 30 heart function?

The life expectancy for congestive heart failure depends on the cause of heart failure, its severity, and other underlying medical conditions. In general, about half of all people diagnosed with congestive heart failure will survive five years. About 30% will survive for 10 years.

What happens when only 20 of your heart is working?

An EF of 20% is about one-third of the normal ejection fraction. This means 80% of the blood stays in the ventricle. The heart is not pumping all the oxygen-rich blood the body needs. The blood that is not ejected from the ventricle can back up into the lungs and cause shortness of breath.

Can a 30 year old have congestive heart failure?

Is heart failure common in younger people? Heart failure in people between the ages of 20–29 years is not common. Still, it is possible a person in their 20s could develop heart failure.

What are the different levels of LVEF?

The simplest classification as per the American College of Cardiology (ACC) that is used clinically as follows: Hyperdynamic = LVEF greater than 70% Normal = LVEF 50% to 70% (midpoint 60%) Mild dysfunction = LVEF 40% to 49% (midpoint 45%) Moderate dysfunction = LVEF 30% to 39% (midpoint 35%)

What is LVEF in ECG?

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 end-systolic volume (ESV). LVEF is calculated from: LVEF: [SV/EDV] x 100

Is LVEF normal with preserved ejection fraction?

Even if you have a normal range LVEF, it doesn’t necessarily mean your heart is “normal.” Some people can have heart failure with a condition that’s known as heart failure with preserved ejection fraction (HFpEF). See below for more details. Mildly reduced.

What is SV and LVEF and how is it calculated?

Stroke volume (SV) is calculated as the difference between end-diastolic volume (EDV) and end-systolic volume (ESV). LVEF is calculated from:
