SIC was calculated as (SI × 100) - estimated creatinine clearance (CCr).

Patients were stratified into two groups based on the optimal cutoff value determined by the receiver-operating characteristic (ROC) curve.

The relationships of GNRI both with phase angle value and QTc were stronger in males and nondiabetic patients. In addition, PR interval was inversely correlated with a phase angle value only in nondiabetic patients. No significant correlation was found between phase angle value and QRS width. Five-year survival probability for the composite endpoints was significantly worse in patients with lower phase angle values. QTc prolongation was associated with survival in males and nondiabetic patients. Prolonged PR was associated with survival in nondiabetic patients.</p><p><strong>Discussion: </strong>Relationships between phase angle value and ECG findings were demonstrated in patients undergoing dialysis, especially in males and nondiabetic patients. Although the phase angle value has been considered as an index for evaluating nutritional status, another clinical application of phase angle value in predicting cardiac complications seems to be useful.</p>","PeriodicalId":9584,"journal":{"name":"Cardiorenal Medicine","volume":" ","pages":"215-226"},"PeriodicalIF":3.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140173851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
