LVEF

Meaning

LVEF stands for Left Ventricular Ejection Fraction, which is a critical clinical measure of the heart’s systolic function, representing the percentage of blood ejected from the left ventricle with each heartbeat. This metric is a fundamental hemodynamic parameter used to assess the efficiency of the heart as a pump. A normal LVEF typically ranges between 55% and 70%; values below this range can indicate impaired myocardial contractility, often leading to a diagnosis of heart failure. Monitoring LVEF is essential in cardiovascular risk assessment, particularly for patients undergoing certain hormonal therapies that may have cardiotoxic potential.
