WebbLeft ventricular ejection fraction (LVEF) is the most widely used parameter of left ventricular (LV) systolic function, and its deterioration is associated with reduced survival rates. 1 LVEF is expressed as a percent value, and calculated by dividing the stroke volume (enddiastolic volume minus end-systolic volume) by the end-diastolic volume and …
Webb22 mars 2015 · As suggested in the question, this number is going to be in the range of 50-55%. Even accepting this general range, there will be a few people with no recognizable heart problem who have an LVEF in the high 40s and many more with clear-cut heart problems who have an LVEF in the high 50s or even the 60s.
