Latest British Society of Echocardiography recommendations for left ventricular ejection fraction categorisation: potential implications and relevance to contemporary heart failure management

摘要

We read with interest the recent guideline publication from the British Society of Echocardiography (BSE) relating to normal reference intervals for cardiac dimensions and function for use in echocardiographic practice (1). We commend the authors and the Education Committee for attempting to produce updated guidance taking into account contemporary, prospective data to determine new reference ranges for echocardiographic parameters. However, we suggest the newly proposed categories for left ventricular ejection fraction (LVEF) derangements from the BSE may contribute to diagnostic and therapeutic uncertainty and create new challenges for the management of heart failure (HF) patients in the United Kingdom (UK).
