まとめ
急性冠症候群(ACS)の最近の患者は、腸内細菌叢異常と認知機能低下を示した。ペプトストレプトコッカスなどの特定の腸内細菌は、ACS生存者の認知機能障害の指標となる可能性がある。
科学分野:
- マイクロバイオーム研究; 心血管医学; 神経科学
背景:
- 腸内細菌叢異常は、認知機能障害および急性冠症候群(ACS)と関連している。最近のACS患者における腸内細菌叢と認知機能の関係はよく理解されていない。
研究 の 目的:
- 最近のACS患者における腸内細菌叢組成と認知機能の調査。ACS患者と心血管リスクの高い対照群との間の腸内細菌叢と認知転帰の比較。
主な方法:
- 50人のACS患者と42人の心血管リスクの高い対照群を登録した。Montreal Cognitive Assessment(MoCA)を用いて神経認知機能を評価した。糞便サンプルの16S rRNA配列解析により腸内マイクロバイオーム組成を解析した。
主要な成果:
- ACS患者は対照群と比較して、すべての領域でMoCAスコアと認知機能が有意に低かった。ACS患者は、Firmicutes/Bacteroidota比およびEnterobacteriaceae/Proteobacteria比の増加を含む、微生物叢の多様性と組成の変化を伴う腸内細菌叢異常を示した。ACS患者における特定の腸内分類群(Peptostreptococcales-Tissierellales、Peptostreptococcus)とMoCAスコアとの間に負の相関が見られた。
結論:
- 腸内細菌叢の変化は、最近のACS患者における認知機能障害と関連している。Peptostreptococcales-TissierellalesおよびPeptostreptococcusは、ACS患者における認知機能障害の潜在的なバイオマーカーとして機能する可能性がある。

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
