Significance of Left ventricular ejection fraction
Left ventricular ejection fraction (LVEF) is a critical measurement that indicates the percentage of blood the left ventricle pumps out with each contraction. It serves as a key metric for evaluating cardiac function, particularly in cases of heart disease. A lower LVEF percentage signifies poorer heart function and can influence treatment decisions, including antiplatelet therapy. Various imaging methods are employed to determine LVEF, making it essential for assessing heart health and monitoring conditions like heart failure.

The concept of Left ventricular ejection fraction in scientific sources
Left ventricular ejection fraction (LVEF) measures the percentage of blood pumped from the left ventricle during contraction, serving as a critical indicator of heart function, with lower values suggesting more severe heart failure.
(1) This measurement, or LVEF, indicates the percentage of blood pumped out of the left ventricle with each heartbeat, and is an important factor in assessing cardiac function.[1] (2) Left ventricular ejection fraction (LVEF) was approximated through eyeballing, with a LVEF below 50% considered abnormal.[2] (3) This is a measurement of the heart's pumping efficiency, and it is often used in studies, with the text discussing different imaging methods for determining the measurement.[3]
(1) This refers to the percentage of blood that the left ventricle of the heart pumps out with each beat, and was a criterion in the ALLHAT study.[4]
(1) This was measured in the study to assess cardiac function, alongside ischaemia and exercise capacity, providing objective measures of heart health in the context of the research.[5]
