Keywords急性心筋梗塞 / 歯周病 / 口腔細菌叢 / 腸内細菌叢 / 口腔内細菌叢
Outline of Research at the Start

①急性心筋梗塞患者において口腔内細菌叢(歯周病菌)と腸内細菌叢のクロストークを検討し、炎症性サイトカインや活性化マクロファージの指標である可溶性葉酸受容体β(FRβ)や血管機能との関連を横断的研究で検討する。
②上記①の急性心筋梗塞患者において歯周病治療あるいは整腸剤におる腸内細菌叢介入を行い、8か月後に歯周病菌と腸内細菌叢検査、冠動脈造影検査、血管機能検査、炎症性サイトカインや可溶性FR-βを再測定して治療介入の効果を前向き研究で検討する。
③動脈硬化モデルマウスのアポ蛋白E欠損マウスに歯周病菌を口腔感染させ、動脈硬化進展への影響を検討するとともに腸内細菌叢介入の効果を検討する。

Outline of Final Research Achievements

In a prospective study, 54 patients who underwent coronary angioplasty for acute coronary syndromes received oral care such as tooth brushing and periodontal care by a dentist for 8 months, and the relationship between oral conditions such as periodontal disease and vascular endothelial function immediately after onset and 8 months later was examined. The results showed that despite oral care, vascular endothelial function was exacerbated after 8 months in patients with severe periodontal disease with periodontal pockets of 6 mm or more (Int Heart J. 2024;65:386-94).
A clinical study of oral and intestinal microflora in acute myocardial infarction is underway with data analysis of saliva and stool samples from 37 acute myocardial infarction patients at the time of admission, with results on oral and intestinal microflora obtained by genetic analysis.

Academic Significance and Societal Importance of the Research Achievements

急性心筋梗塞や不安定狭心症などの急性冠症候群で急性期に冠動脈形成術を施行した患者54名中24名(44.4%)が歯周ポケット6mm以上の重症歯周病を併存しており、急性冠症候群と歯周病との関連が示唆された。また、重症歯周病患者では、口腔ケアを行ったにもかかわらず、血管内皮機能が増悪することが明らかになり、更なる厳格な歯周病治療や口腔ケアが必要なことが示唆された。急性冠症候群と歯周病との関連が明らかになり、医科と歯科の連携の重要性が確認された。急性心筋梗塞における口腔細菌叢と腸内細菌叢のクロストークが明らかになれば、歯周病治療や腸内細菌叢介入などの治療法の開発に繋がることが期待される。
