ABCA1 and coronary artery disorder: In another way, in patients medicated with metformin, miR-26a-5p expression levels were higher in the unmedicated CAD patients compared with the CG (p = 0.029), while expression in CAD patients was lower for miR-33a-5p and ABCA1 mRNA, when compared to the CG, as well as in unmedicated versus medicated CAD patients (p ≤ 0.05).
