MT-ND1 and septic shock: Compared with post-CABG patients, the free-circulating ND1 mtDNA levels were significantly higher at onset in septic shock patients; however, septic shock levels did not differ significantly compared with those in patients undergoing MAS (septic shock onset vs. CABG postoperative: p < 0.001; septic shock onset vs. MAS postoperative: p = 1.0; CABG postoperative vs. MAS postoperative: p = 0.021).
