摘要

在本文中，我们强调了患者在心功能评估中对左心室射血分数正常值的普遍误解。这种误解源于比例优势效应，即个人倾向于根据比例而非绝对值进行判断。我们解释了这种误解是如何影响患者的情绪和医疗依从性，从而导致更差的临床结果。为了解决这个问题，我们引入了 "左心室射血分数-正常比例 "的概念，将左心室射血分数调整到患者特定的正常范围。这种以患者为中心的方法旨在通过比例的视角传达准确的信息，从而提高患者的理解力、参与度和依从性，进而改善临床疗效。

Left ventricular ejection fraction: time to revise the metric?

In this paper, we highlight the prevalent misconception among patients regarding the normal value of left ventricular ejection fraction in cardiac function assessment. This misconception arises from the proportion dominance effect, wherein individuals tend to judge based on proportions rather than absolute values. We explain how this misunderstanding impacts patient demoralization and medical adherence, leading to worse clinical outcomes. To address this, the concept of "Left Ventricular Ejection Fraction - Proportion of Normal" is introduced, which adjusts left ventricular ejection fraction to a patient-specific normal range. This patient-centric approach aims to enhance comprehension, engagement, and adherence by conveying accurate information through the lens of proportions, thereby potentially improving clinical outcomes.

期刊介绍： Postgraduate Medical Journal is a peer reviewed journal published on behalf of the Fellowship of Postgraduate Medicine. The journal aims to support junior doctors and their teachers and contribute to the continuing professional development of all doctors by publishing papers on a wide range of topics relevant to the practicing clinician and teacher. Papers published in PMJ include those that focus on core competencies; that describe current practice and new developments in all branches of medicine; that describe relevance and impact of translational research on clinical practice; that provide background relevant to examinations; and papers on medical education and medical education research. PMJ supports CPD by providing the opportunity for doctors to publish many types of articles including original clinical research; reviews; quality improvement reports; editorials, and correspondence on clinical matters.
