OBJECTIVE: To investigate the effect of high-dose glucose-insulin-potassium (GIK) infusion on the outcomes of ST-elevation myocardial infarction (STEMI) in China.
METHODS: As part of the international multicentre CREATE-ECLA study, 7510 patients with STEMI, aged (62 +/- 12), presenting their symptoms within 12 hours of onset who were hospitalized in 274 centers throughout China from July 2001 through July 2004 were randomized to receive GIK intravenous infusion for 24 hours plus routine treatment (3739) or control group (n=3771) receiving routine treatment alone. The patients were flowed up in the out-patient department 30 days after the randomization to assess the rates of mortality, cardiac arrest, cardiogenic shock and re-infarction.
RESULTS: The median time from symptom onset to randomization was 5.8 hours. The mortality of the control group was 10.4%, not significantly different from that of the GIK group (11.2%, hazard ratio = 1.05, 95% CI: 0.916-1.207, P = 0.476). There rates of cardiac arrest, cardiogenic shock, and re-infarction of the GIK group were 0.8%, 6.8%, and 2.0% respectively, all not significantly different from those of the control group (1.0%, 6.4%, and 1.9% respectively, all P > 0.05). At the Day 7 the heart failure rate of the GIK group was 19.7%, not significantly different from that of the control group (18.3%, P = 0.102). The symptomatic hypotension rate of the GIK group was 3.7%, significantly higher than that of the control group (1.2%, P < 0.01). The phlebitis rate of the GIK group was 2.2%, significantly higher than that f the control group (0.1%, P < 0.01). The net increased fluid volume of the control group wasl3 584 ml. more than that of the GIK group (1036 ml).
CONCLUSIONS: High dose GIK infusion has neutral effect on mortality, cardiac arrest or cardiogenic shock in patients with acute STEMI in China.
