Abstract

Aims: A nutritional status is related to the length of hospitalization and in-hospital mortality of patients with heart failure (HF). The aim of this study is to assess the prognostic impact of nutritional status and body mass index (BMI) on in-hospital mortality among patients with HF relative to their sex.

Methods and results: We conducted a retrospective study and analysis of 809 medical records of patients admitted to the Institute of Heart Disease of the University Clinical Hospital in Wroclaw (Poland). Women were statistically significantly older than men (74.67 ± 11.15 vs. 66.76 ± 17.78; P < 0.001). In unadjusted model, significant predictors of the odds of in-hospital mortality for men were underweight (OR = 14.81, P = 0.001) and the risk of malnutrition (OR = 8.979, P < 0.001). In the case of women, none of the traits analysed was significant. In age-adjusted model, significant independent predictors of the odds of in-hospital mortality in the case of men were BMI < 18.5 (OR = 15.423, P = 0.001) and risk of malnutrition (OR = 5.557, P = 0.002). In the case of women, none of the nutritional status traits analysed were significant. In multivariable-adjusted model in men, significant independent predictors of the odds of in-hospital mortality were BMI < 18.5 (OR = 15.978, P = 0.007) compared with having normal body weight and the risk of malnutrition (OR = 4.686, P = 0.015). In the case of women, none of the nutritional status traits analysed were significant.

Conclusion: Both underweight and the risk of malnutrition are direct predictors of the odds of in-hospital mortality in men, but not in women. The study did not find a relationship between nutritional status and in-hospital mortality in women.

营养状况对心力衰竭患者院内死亡率影响的性别差异:一项回顾性队列研究。
目的:营养状况与心力衰竭(HF)患者的住院时间和院内死亡率有关。本研究旨在评估营养状况和体重指数(BMI)对心力衰竭患者院内死亡率的预后影响:我们对波兰弗罗茨瓦夫大学临床医院心脏病研究所收治的 809 名患者的病历进行了回顾性研究和分析。据统计,女性明显比男性年长(74.67 ± 11.15 vs. 66.76 ± 17.78;P < 0.001)。在未经调整的模型中,男性院内死亡几率的重要预测因素是体重不足(OR = 14.81,P = 0.001)和营养不良风险(OR = 8.979,P < 0.001)。就女性而言,所分析的特征均不显著。在年龄调整模型中,BMI<18.5(OR = 15.423,P = 0.001)和营养不良风险(OR = 5.557,P = 0.002)是男性院内死亡几率的重要独立预测因素。就女性而言,所分析的营养状况特征均不显著。在男性的多变量调整模型中,与体重正常和营养不良风险(OR = 4.686,P = 0.015)相比,BMI < 18.5(OR = 15.978,P = 0.007)是院内死亡几率的重要独立预测因素。就女性而言,所分析的营养状况特征均不显著:结论:体重不足和营养不良风险是男性院内死亡几率的直接预测因素,但不是女性的直接预测因素。研究没有发现女性营养状况与住院死亡率之间的关系。
