Plasma Mitochondrial Coupling Factor 6 in Patients with Acute Myocardial Infarction

Previous studies have shown that mitochondrial coupling factor 6 (CF6) is an endogenous peptide that inhibits prostacyclin (PGI2) synthesis in vascular endothelial cells. In this study, we measured the plasma CF6 level of patients with acute myocardial infarction (AMI) to observe dynamic changes of...

Zusammenfassung:Previous studies have shown that mitochondrial coupling factor 6 (CF6) is an endogenous peptide that inhibits prostacyclin (PGI2) synthesis in vascular endothelial cells. In this study, we measured the plasma CF6 level of patients with acute myocardial infarction (AMI) to observe dynamic changes of CF6. All patients showed elevated plasma CF6 levels upon admission for treatment of AMI. Their CF6 levels peaked approximately 72 h after the onset of AMI and remained high for 7 days. At 7 days, their CF6 levels decreased to the level seen upon admission, but not to within a normal range. Hyperlipidemic patients had significantly greater CF6 levels at 24 h after onset of AMI than patients with a normal lipid profile. On admission, the plasma CF6 level in patients with a cardiac function of Killip class ≥II was higher than that in patients with a Killip class I cardiac function. At 3 days after the onset of AMI, the plasma CF6 levels of patients with a creatinine kinase (CK) peak value ≥1,500 units/l were significantly higher than those of patients with a CK peak value
