Research Abstract

経皮的冠動脈インターベンションが予定された安定狭心症患者を対象とし、血中Lp-PLA2活性とculpritlesionおよびnon-culpritlesionにおけるプラーク組成との関連について検討を行った。冠動脈プラーク組成についてはVirtualHistologyIVUSにてnecrotic core・fibrolipid・fibrosis・calcificationの4つの組織性状に分類した。Culprit lesionのプラークにおいて、Lp-PLA2活性はMLDでのfibrolipid率およびMLDを中心とする10mmプラークでのfibrolipid率と有意な正相関を認めた。また、non-culprit lesionのプラークにおいて、Lp-PLA2活性はMLDでのfibrolipid率・MLDを中心とする10mmプラークでのfibrolipid率・MLDでのfibrolipid面積・MLDを中心とする10mmプラークでのfibrolipid体積と有意な正相関を認めた。その他のプラーク組成であるnecrotic core・fibrosis・calcificationとLp-PLA2活性とは有意な相関を認めなかった。一方、急性心筋梗塞と安定狭心症ではLp-PLA2活性に有意差を認めなかった。
本研究の結果より、Lp-PLA2活性の高い患者の冠動脈プラークは脂質成分に富んだ不安定プラークが多いことが示された。このプラーク特性はculprit lesionのみならずnon-culprit lesionにも(むしろ強く)認められた。Lp-PLA2に対する薬物学的インターベンションは、虚血性心疾患2次予防において有用な治療戦略になりえるかもしれない。
本研究の結果については、現在、論文の作成中である。
