LVEF
Pronunciation: el-vee-ee-ef
Also written as: LVEF — Left Ventricular Ejection Fraction
Left ventricular ejection fraction, a key measurement of heart pump function used in cardiac rehabilitation assessment.
Full Definition
Left ventricular ejection fraction (LVEF) is the percentage of blood pumped out of the left ventricle with each heartbeat, serving as a primary indicator of cardiac function. Normal LVEF ranges from 50-70%, while reduced LVEF (typically <40%) indicates heart failure and requires modified rehabilitation protocols. In cardiac rehabilitation documentation, LVEF values guide exercise prescription, risk stratification, and progression monitoring. Healthcare professionals use this measurement to determine appropriate activity levels and monitor patient improvement throughout the rehabilitation process.
Usage
Usage note: Express as percentage; distinguish from right ventricular ejection fraction (RVEF)
In Context
- "The patient's LVEF improved from 35% to 45% following 12 weeks of supervised exercise training." — progress note
- "Exercise intensity was limited due to severely reduced LVEF of 25%." — rehabilitation plan
