摘要:
目的 探讨相位角（PA）在经导管主动脉瓣置换术（TAVR）患者术前营养状况评估中的价值及其对临床预后的影响。方法 选择拟行TAVR患者154例分为低PA组（n=71）和正常PA组（n=83）。比较两组患者的体成分、血清学及预后指标分析PA与各指标的相关性。采用多因素logistic回归分析患者营养不良的影响因素。结果 低PA组膳食蛋白质摄入量、血红蛋白、淋巴细胞计数、白蛋白、体、上臂肌围腰围低于正常PA组。心脏监护病房观察时间、住院时间、术后感染发生率、180再入院率高于正常PA组。PA与膳食蛋白质摄入量、血红蛋白、淋巴细胞计数、白蛋白、体、上臂肌围腰围呈正相关。PA与心脏监护病房观察时间、住院时间呈负相关（P<0.05）。较低PA（OR=P=0.034）TAVR患者营养不良。结论 TAVR患者术前营养临床预后密切相关PA可成为术前营养
Abstract:
Objective To investigate the role of phase angle(PA) in preoperative nutritional status assessment and its impact on clinical prognosis in patients undergoing transcatheter aortic valve replacement(TAVR). Methods A total of 154 patients undergoing TAVR were selected and divided into the low PA group(n=71) and the normal PA group(n=83). The body composition,serological and prognostic indices were compared between two groups. The correlation between PA and each index was analyzed. Multivariate logistic regression analysis was used to analyze the influencing factors of malnutrition. Results The dietary protein intake,hemoglobin level,lymphocyte count,albumin level,body mass index,arm muscle circumference,and waist circumference of the low PA group were lower than those of the normal PA group. The observation time in CCU,hospital stay,incidence of postoperative infection,and 180-day readmission rate in the low PA group were higher than those in the normal PA group. PA was positively correlated with dietary protein intake,hemoglobin level,lymphocyte count,albumin level,body mass index,arm muscle circumference,and waist circumference. PA was negatively correlated with observation time in CCU and hospital stay(P<0.05). Lower PA(OR=0.324，P=0.034) was associated with a higher risk of malnutrition in TAVR patients. Conclusion Low PA is an independent risk factor for preoperative malnutrition in TAVR patients and is closely related to postoperative clinical prognosis. PA can become an effective tool for preoperative nutritional assessment
