Cholesterol efflux capacity was quantified in blood samples from the cohort of healthy volunteers as described previously.
This assay quantifies total efflux mediated by pathways of known relevance in cholesterol efflux from macrophages (i.e., ATP-binding cassette transporter A1 [ABCA1] and G1 [ABCG1], scavenger receptor B1, and aqueous diffusion):

この指標は、冠動脈石灰化(CAC)、家族歴(FH)、hs-CRPなどの既知予測要素を上回るか?
Dallas Heart Study (DHS)登録車でのベースラインASCVDなしの被検者で、ASCVDイベント予測比較
ASCVD:初回心筋梗塞・卒中・冠動脈再建・心血管死亡
9.4年間フォローアップ
被検者(N=1972)平均年齢45歳、CAC 52%(>0)、FH 31%、hs-CRP(2mg/L以上)58%
CEC中央値超例は、ASCVD発生50%減少と関連
CAC (5.4% vs. 10.5%; p = 0.003)
FH (5.8% vs. 10%; p = 0.05)
高値hs-CRP (3.8% vs. 7.9%; p = 0.004)
CECは、以下の項目追加で判別・再分類メリットすべて改善
CAC (c-statistic, p = 0.004; IDI, p = 0.02; NRI: 0.38; 95% confidence interval [CI]: 0.13 to 0.53)
FH (c-statistic, p = 0.006; IDI, p = 0.008; NRI: 0.38; 95% CI: 0.13 to 0.55)
高値hs-CRP (c-statistic p = 0.008; IDI p = 0.02; NRI: 0.36; 95% CI 0.12 to 0.52)
CEC標準化されれば、心血管リスク予測に極めて役立つ可能性
