Prognostic models for patients suffering a heart failure with a preserved ejection fraction: a systematic review.

The purpose of this study was to systematically review the development, performance, and applicability of prognostic models developed for predicting poor events in patients with heart failure with preserved ejection fraction (HFpEF). Databases including Embase, PubMed, Web of Science Core Collection, the Cochrane Library, China National Knowledge Infrastructure, Wan Fang, Wei Pu, and China Biological Medicine were queried from their respective dates of inception to 1 June 2023, to examine multivariate models for prognostic prediction in HFpEF. Both forward and backward citations of all studies were included in our analysis.

Death and do-not-resuscitate order in the emergency department: A single-center three-year retrospective study in the Chinese mainland.

Background: Consenting to do-not-resuscitate (DNR) orders is an important and complex medical decision-making process in the treatment of patients at the end-of-life in emergency departments (EDs). The DNR decision in EDs has not been extensively studied, especially in the Chinese mainland.

Methods: This retrospective chart study of all deceased patients in the ED of a university hospital was conducted from January 2017 to December 2019.
