射血分数保留的心力衰竭(heart failure with preserved ejection fraction,HFpEF)是一种具有多种临床表现的综合征。将病理生理表型相同的患者进行分类,可以使他们得到更好的针对性治疗。在HFpEF患者中,肥胖这一症状非常常见,可引发多种心血管效应,这表明可以根据肥胖对患者进行表型分类。方法: Heart failure with preserved ejection fraction (HFpEF) is a syndrome with multiple clinical manifestations. Classifying patients with the same physiopathological phenotype allows them to be better targeted. In HFpEF patients, the symptom of obesity is very common and can trigger a wide range of cardiovascular effects, suggesting that patients may be phenotypically classified based on obesity. method:
