Key result
LVEF limitations as a composite of arterial and ventricular elastances require deeper hemodynamic understanding.
Why the study?
Left ventricular ejection fraction is a critical parameter for heart failure management, but clinicians need to be aware of its limitations as a volumetric ratio rather than a measure of intrinsic contractility.
Clinicians should be aware of the limitations of left ventricular ejection fraction and seek a more comprehensive understanding of cardiac hemodynamics.
Left ventricular ejection fraction is the critical parameter used for heart failure classification, decision making and assessing prognosis. It is defined as a volumetric ratio and is essentially a composite of arterial and ventricular elastances, but not intrinsic contractility. The clinician should be aware of its numerous limitations when measuring and reporting it. And make a step toward more insightful understanding of hemodynamics.
