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 . 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 mention one of these two EF-related scenarios: 1. Preserved ejection fraction (HFpEF)– also . See more
Your 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 moreWith respect to the lower limit of “normal” LVEF, it is important to remember that even at rest, the LV pumps a slightly different amount of blood in every beat. Things like time of day (biological cycles), eating (what and when), position (supine vs. upright), breathing, medications, etc. can all slightly change LVEF in a normal person. A normal heart’s ejection fraction is between 55 and 70 percent. This indication of how well your heart is pumping out blood can help to diagnose and track heart failure. It is important to note, however, that you can have a normal ejection fraction measurement and still have heart failure.
∗ LV size applied only to chronic lesions. Normal 2D measurements: LV minor axis ≤ 2.8 cm/m 2 , LV end-diastolic volume ≤ 82 ml/m 2 , maximal LA antero-posterior diameter ≤ 2.8 cm/m 2 , maximal LA volume ≤ 36 ml/m 2 (2;33;35).Left ventricular ejection fraction (LVEF) has been a key variable for the diagnosis and management of heart failure over the last three decades.

Assessment of LV function remains the most common reason for cardiac imaging because of its powerful ability to predict morbidity and mortality. Current routine methods of quantifying LV function (with LVEF) is not without limitations. An accurate left ventricle ejection fraction (LVEF) reading can be measured through a variety of imaging techniques. The most common ejection fraction testing measures include:.GLS should be measured in the 3 standard apical views (apical 4 chamber, 2 chamber and long axis) and the average GLS should be reported. Normal values depend on several factors including the vendor and version of software. As a general guide, peak GLS of -20% can be considered normal.The reference ranges for left ventricular (LV) global longitudinal strain and right ventricular free-wall strain were −24% to −16% and −35% to −17%, respectively. Correspondingly, left atrial (LA) and right atrial (RA) reservoir strains were 17% to 49% and 17% to 59%.
Ejection fraction is the fraction of the end-diastolic volume (EDV, i.e blood volume in the ventricle at the end of diastole) that is pumped out during systole. Currently, two-dimensional (2D) echocardiography for calculation of ejection fraction is the dominant method for assessing left ventricular function (systolic function).Assessment of the size, mass, geometry, and function of the left ventricle is fundamental for the diagnosis and prognosis of most cardiac diseases, including coronary artery disease, heart failure, arrhythmias, structural heart disease, etc.
An historic. | Grammarist. | Usage. In all main varieties of English, the use of an as the article preceding historic ( an historic) is an unnecessary affectation. The rule for the indefinite article is that we use a before words beginning with a consonant sound, and an before words beginning with a vowel sound.
