Outline of Final Research Achievements

A total of 45 outpatients (mean age 67.1 ± 10.2 years) who had previously experienced a transient ischemic attack or a minor non-cardioembolic ischemic stroke at a single hospital in Japan. RIS occurred in 9 patients; they had significantly higher visceral fat level (p = 0.007) and %body fat (p = 0.007) values and lower MVPA (p = 0.011) values than patients without recurrence. A multivariate analysis of these factors indicated that age, visceral fat level and MVPA were significant independent predictors of RIS.

Academic Significance and Societal Importance of the Research Achievements

TIAおよび非心原性の軽症脳梗塞の再発を経験した患者は中強度以上の身体活動量が低く、内臓脂肪レベルが高かった。低い中強度以上の身体活動量と内臓脂肪型肥満の保有は脳梗塞再発リスクの指標となる可能性が指摘された。このことは脳梗塞再発のリスク評価においては、BMIや体脂肪よりもVFLの精度が高い可能性を示している。BI法は侵襲がない簡便な測定用具であり、臨床の様々な診療科で使用されている。今後は軽症脳梗塞患者の再発予防においても、BI法の有用性を検討していく必要がある。
