本研究的研究對象為腎病末期接受血液透析患者,且參與數量僅有
72 位,難以將研究結論據此外推至所有接受血液透析或者其他種類透析 的患者。若後續能將各類透析患者包含在內,並增加研究對象的數量,
對於 baPWV 的預測角色或許能更明確顯現,這是值得繼續努力的一個 方向。對於一般民眾,雖有探討 baPWV 與性別、年齡以及具冠心病危 險因子者之間的相關性,但針對無症狀的民眾,其 baPWV 與心律不整 之間的關聯,仍未能有系統及前瞻性的研究。
以醫療政策制定者而言,若能發展低成本的篩檢工具,早期自一般 民眾中診斷出高危險群,給予預防性的治療,可以降低罹病率及死亡 率,減少醫療資源的耗用,因此值得吾人繼續研究探討。
