背景：对保留射血分数（HFpEF）心力衰竭患者进行营养风险评估的临床意义尚不明确。老年营养风险指数（GNRI）是一种简单的老年人营养评估工具。在HFpEF患者中评估其预测价值，HFpEF是老年人群中常见的HF表型。方法和结果：本研究纳入了152例在作者所在医院因HFpEF住院的连续患者（平均年龄77±11岁，男性53.9%）。入院时GNRI计算公式为：14.89 ×血清白蛋白(g/dl)+41.7 ×体重指数/22。比较两组患者的特征和死亡率（中位随访时间为2.1年）：
Background: The clinical significance of nutritional risk assessment in patients with heart failure with preserved ejection fraction (HFpEF) remains undefined. Geriatric nutritional risk index (GNRI) is a simple nutritional assessment tool for elderly subjects. Its predictive value was evaluated in patients with HFpEF, a common HF phenotype in the elderly population.Methods and Results: The present study enrolled 152 consecutive patients (mean age, 77 +/- 11 years; male, 53.9%) who were hospitalized with HFpEF at the authors' institution. GNRI on admission was calculated as follows: 14.89xserum albumin (g/dl)+41.7xbody mass index/22. Characteristics and mortality (median follow-up of 2.1 years) were compared between 2 groups: low GNRI (
