Prognosis of Low Normal Left Ventricular Ejection Fraction in an Asymptomatic Population-based Adult Cohort. MESA

摘要

BackgroundReduced left ventricular systolic function predicts worse outcomes. However, the optimal threshold for “normal” left ventricular ejection fraction (LVEF) is uncertain. In general LVEF ≥ 55% is considered “normal” by guidelines, with a low normal designation for LVEF 50-55%. We assess the prognosis of participants with low normal LVEF in the Multi Ethnic Study of Atherosclerosis. All participants were asymptomatic and had no known clinical CVD at baseline.
