RT Journal A1 Rensing KL, Kastelein JP, Twickler M T1 IS insulin the preferred compound in lowering glucose levels in patients after a myocardial infarction? JF Archives of Internal Medicine JO Archives of Internal Medicine YR 2009 FD September 28 VO 169 IS 17 SP 1633 OP 1638 DO 10.1001/archinternmed.2009.326 UL http://dx.doi.org/10.1001/archinternmed.2009.326 AB Looking at their interesting observations, we wonder whether insulin should be used as the preferable compound to lower glucose levels. From Figure 2 of their article,1 the in-hospital mortality appeared to be more pronounced in patients who were treated with insulin (although not significant) compared with non–insulin-treated patients. This trend was present along almost all glucose level intervals. Therefore, these results might suggest a less beneficial outcome in those hyperglycemic patients treated with insulin.
