The toe‒brachial pressure index as a predictor of mortality in hemodialysis patients

Abstract: 維持血液透析患者における生命予後予測因子としての 足趾上腕血圧比(Toe brachial pressure index)の有用性 1 小田原循環器病院心臓リハビリテーション室 2 小田原循環器病院腎臓内科 3 小田原循環器病院循環器内科 4 神奈川工科大学健康医療科学部臨床工学科 キーワード:生命予後,足趾上腕血圧比,血液透析,末梢動脈疾患 〈要旨〉 維持血液透析(HD)患者における足趾上腕血圧比(TBI)の予後予測因子としての有用性は不明である.本研究で は足関節上腕血圧比(ABI) ,TBI,皮膚灌流圧(SPP)を検査した 157 名の HD 患者の 5 年後の生存の有無と因子 を用いて予後因子解析を行った.Cox proportional hazards model を用いた検定の結果,TBI は独立予後因子であっ た(p <0.001) .また死亡予測の ROC 曲線では,TBI の cut off 値が 0.56,曲線下面積は TBI 0.91 で予測能が最も高 かった.算出された TBI の cut off 値を用いて TBI≧0.7 群,0.7>TBI≧0.56 群,TBI<0.56 群および Ze… Show more

“…Since calcification of the tunica media in the arteries rarely extends to the toe arteries, the toe brachial index (TBI) has been used as an index to evaluate impaired blood circulation in the peripheral arteries, and its usefulness has been reported in both diabetic patients 4) and HD patients. 5,6) Some drawbacks of the measurement of the TBI are that it cannot be measured in the presence of involuntary movements, small-muscle cramps, arrhythmias, or blood pressure ≤40 mmHg. Recently, other screening tests have been attempted to determine skin microcirculation adequacies, such as skin perfusion pressure and transcutaneous oxygen tension.…”
