心脏移植患者的营养不良可能会影响生存。目的是根据营养风险指数（NRI）调查接受移植的男性和女性心脏移植患者术前和术后 1 年的生存和营养状况。对利雅得费萨尔国王专科医院 90 名心脏移植患者（2009 年至 2014 年）的医疗记录进行了审查。评估包括人口统计数据、人体测量和 NRI 计算。此外，术后数据包括住院时间和生存率。使用配对 t 检验和 Kaplan-Meier (KM) 曲线的生存分析。总共纳入 90 名患者（男性 77.78%）。 NRI 术前阶段营养不良患病率为 60%（NRI 评分为重度营养不良 7.78%；中度营养不良 40%；轻度营养不良 12.22%）。 1 年后，体重指数 (BMI) 和 NRI 显着增加 (p < 0.001)。此外，男性和女性之间的 NRI 存在显着差异（p < 0.01），而 KM 生存曲线则无显着差异（p = 0.67）。术后存在中度或重度营养风险（NRI < 97.5）的受者在移植后第一年的生存期显着缩短（HR = 0.82；95% CI，0.75-0.89；p < 0.001）。我们的研究结果表明，移植 1 年后的 NRI 与死亡率显着相关。此外，生存率没有显着的性别差异；然而，营养不良和低存活率在妇女中更为突出。
Malnutrition among heart-transplant patients may affect survival. The aim was to investigate the survival and nutrition status among male and female heart transplant patients who underwent transplantation, before and 1 year after surgery based on the nutritional risk index (NRI). The medical records of ninety heart-transplant patients (2009–2014) from the King Faisal Specialist Hospital, Riyadh, were reviewed. The assessment included demographic data, anthropometric measurements, and NRI calculation. Moreover, postoperative data included the length of stay and survival. Paired t-test and survival analysis by Kaplan–Meier (KM) curves were used. A total of 90 patients (males 77.78%) were included. The prevalence of malnutrition in the preoperative phase by NRI was 60% (7.78% as severe; 40% as moderate, and 12.22% mild NRI scores). After 1 year, body mass index (BMI) and NRI increased significantly (p < 0.001). Furthermore, NRI was significantly different between men and women (p < 0.01), while KM survival curves were insignificantly different (p = 0.67). Recipients with postoperative moderate or severe nutritional risk (NRI < 97.5) had significantly shorter survival in the first-year post-transplantation (HR = 0.82; 95% CI, 0.75–0.89; p < 0.001). Our findings indicate that the NRI after 1 year of transplant correlated significantly with mortality. Besides, there was no significant gender difference regarding survival; however, malnutrition and low survival were more prominent among women.
