Ejection fraction (EF) is a popular but conceptually flawed metric for assessing heart pumping capacity. This review explores its limitations and proposes alternative methods using standard measurements.
Area of Science:
- Cardiology
- Biomedical Engineering
- Medical Statistics
Background:
- Ejection fraction (EF) is widely used to evaluate ventricular and atrial pumping capacity.
- Despite its ease of calculation and perceived reflection of performance, EF has conceptual weaknesses.
Purpose of the Study:
- To critically analyze the conceptual limitations and statistical irregularities of ejection fraction (EF).
- To explore the reasons behind the traditional popularity of EF in cardiology.
- To propose alternative metrics for assessing cardiac function.
Main Methods:
- Conceptual analysis of the ejection fraction (EF) metric.
- Graphical representation of EF's dependence on end-systolic volume (ESV) and end-diastolic volume (EDV).
- Review of existing literature on EF's application and limitations.
Main Results:
- EF's numerical value is strictly determined by ESV and EDV, highlighting a mathematical dependency.
- The study identifies intrinsic shortcomings and statistical irregularities associated with EF.
- Misleading attractiveness of EF is discussed in the context of its widespread use.
Conclusions:
- Ejection fraction (EF) is conceptually suboptimal for assessing cardiac performance.
- Alternative methods exist that offer logical improvements without requiring additional data.
- A re-evaluation of EF's role in cardiology is warranted.
