Mitochondrial Ferritin Inhibition Aggravates Pacing-induced Ventricular Arrhythmias after Myocardial Infarction by Promoting Cardiomyocytes Ferroptosis

Our findings suggest that FtMt serves as a protective function in myocardial infarction by limiting infarct size, reducing the incidence of ventricular arrhythmias, and inhibiting ferroptosis both in vivo and in vitro. Our results also indicate that FtMt could be a promising therapeutic target for myocardial infarction. The RNA sequencing results of mice cardiac tissue from Sham and MI groups showed that differently expressed genes enriched in “ferroptosis”
