背景:心力衰竭(HF)综合征是一种异质性疾病。虽然可由射血分数(EF)和舒张功能来定义HF,但描述社区中HF特征的资料少见,因为大多数研究都是基于医院的回顾性研究并依赖有临床指征的检验。此外,很少运用标准化技术系统性评估舒张功能。目的:前瞻性检测社区HF居民的EF、舒张功能和脑利钠肽(BNP)水 Background: Heart failure (HF) syndrome is a heterogeneous disease. Although HF can be defined by ejection fraction (EF) and diastolic function, data describing HF signatures in the community are uncommon because most studies are based on hospital-based retrospective studies and rely on tests with clinical indications. In addition, the systematic use of standardized techniques is rarely evaluated for diastolic function. PURPOSE: To prospectively detect EF, diastolic function and brain natriuretic peptide (BNP) water in community HF residents
