WebDefinition 2: LVEF decrease to ≤ 40% in patients with previous LVEF ≥ 50%, or a 10% absolute reduction in patients with baseline LVEF < 50%. This definition is based on the fact that an absolute reduction in LVEF ≥ 10% would be more clinically relevant than an absolute reduction in LVEF ≥ 5% . WebLVEF is defined as the ratio of stroke volume to end-diastolic volume, and is the most used metric in the assessment of LV function. From: Cardio-Oncology, 2024. Related terms: …

Ejection fraction (EF) refers to how well your left ventricle (or right ventricle) pumps blood with each heart beat.
