Representative high-resolution ESI/FTMS spectra of whole cTnI (M28+) purified from (A) postmortem and (B) fresh transplant human heart samples. A, i) NOR2; ii) HYP3; and B, i) DOR1; (ii) ICM3. Roman numerals (II–IV) indicate three different C-terminally truncated isoforms of N-terminally acetylated cTnI (II, 1–207; III, 1–206, IV, 1–205). Subscripts p and pp stand for mono and bisphosphorylation. +H3PO4, non-covalent adduct of phosphoric acid. Asterisks indicate co-purified minor cTnT related products. NOR, control heart with normal function; HYP, mild hypertrophy; DOR, donor heart; ICM, ischemic cardiomyopathy. Clinical details of the myocardial tissue samples were shown in Table S1–2.
