Background: Fibroblast growth factor 21 (FGF21) is a novel myokine released from skeletal muscle. Recent studies have showed that FGF21-transgenic mice had low plasma levels of insulin-like growth factor-1, a potent tissue survival factor, in ischemic myocardium following acute myocardial infarction (AMI).
Objective: To examine a role of FGF21 in subsequent complication after AMI.
Methods: Patients experiencing their first AMI (n=71, mean age 62.4±10.1 years old) was employed. Successful coronary reperfusion was accomplished within 12 hours in all patients. Plasma FGF21 levels were measured on admission, and 7 days and 6 months after onset. Left ventricular (LV) remodeling was assessed by left ventriculography on the day of admission and 6 months after AMI.
Results: Levels of FGF21 in plasma peaked on admission and had declined by 6 months (admission: 611±40, day 7: 246±23, 6 months: 316±24 pg/ml, P<0.001). The FGF21 levels were correlated with plasma lactate levels on admission (r=+0.26, P=0.03). The LV end-diastolic volume index (LVEDVI) significantly increased 6 months after AMI (admission: 79.5±2.4, 6 months: 84.5±2.9 ml/m 2 , P=0.004). The FGF 21 levels on admission were positively correlated with the changes in LVEDVI (r=+0.23, P=0.04). The multivariate regression analysis showed that the plasma FGF21 levels on admission was a significant explanatory variable for the changes in LVEDVI (β=+0.232, P=0.041).
Conclusions: These results suggest that a novel myokine, FGF21, reflects circulatory insufficiency and could be a marker for late-stage LV remodeling after AMI.
