Most importantly, MP infection leads to more severe myocardial injuries, with the MP group showing significantly elevated biomarkers, including cardiac troponin (CTnI, μ g/L; 0.15 ± 0.31 vs. 0.021 ± 0.028; p = 0.025), myoglobin (Mb, ng/mL; 20.43 ± 11.86 vs. 7.20 ± 17.67; p = 0.018), and N-terminal pro B-type natriuretic peptide (NT-proBNP, pg/mL; 5152.92 ± 5536.38 vs. 925.95 ± 2368.25; p = 0.019). Here, MB is linked to hyperplastic polyp.
