- Contribution of severe LV systolic dysfunction to SCD in the
general population. LVEF 35% is currently the risk predictor most
widely used in clinical practice. However, findings from the Oregon
Sudden Unexpected Death Study revealed that severe LV dysfunction
affects less than one-third of all cases of SCD in the general
population Oregon sudden death study
