    Abstract:
    OBJECTIVE: This study was designed to evaluate reperfusion therapy, co-administered with high dose glucose-insulin-potassium (GIK) treatment on serum soluble Fas/APO-1 (sFas) and Fas ligand (sFasL) concentration in Acute Myocardial Infarction (AMI) patients. METHODS: Seventy-four patients with AMI underwent reperfusion therapy were randomized into GIK group (n = 35) receiving high-dose GIK for 24 hours or a vehicle group (n = 39). Thirty-four control subjects (NC) were also enrolled in the present study. Strepavidin-biotin ELISA was used to determine the serum sFas and sFasL concentration at baseline and different time point (24 h, 3 d, 7 d and 14 d) after reperfusion. RESULTS: (1) The serum concentration of sFas and sFas-L ([sFas] and [sFas-L]) of AMI patients were significantly elevated at baseline as compared with NC (P < 0.01). (2) The [sFas] in GIK and non-GIK group decreased 24 h after reperfusion (P < 0.01 vs. baseline) and then increased during 3-7 d period (P < 0.01 vs. 24 h). (3) The GIK group demonstrated reduced [sFas] at 14 d (P < 0.01 vs. 7 d), with no concomitant changes in the non-GIK group. (4) The [sFasL] in the GIK and non-GIK group were no significant difference during 3-14 d period. CONCLUSION Owing to cardioprotective effects reported here and by others, a high-dose GIK infusion co-administered with the timely establishment of perfusion should be strongly considered as a treatment of choice for AMI.
