Figure 4.

M6A levels in the blood of 12 patients after myocardial infarction (MI): association with ejection fraction (EF) (A), peak levels of cardiac markers CPK (B), cTnT (C), and admission levels of Nt-proBNP (D). Six patients developing heart failure 4 months after MI (EF ≤ 40%), and 6 patients with preserved EF (>50%) were included. M6A levels in total RNA extracted from whole blood samples collected at the time of reperfusion were quantified by LC-MS. Spearman correlation coefficients and p-value are indicated.
