Patients were categorised into 4 groups: hypoglycaemia group (N=443, 23.9%), FPG≤5 mmol/l; euglycaemia group (N=812, 43.8%), FPG≥ 5.1 to≤7.0 mmol/l (5–7 mmol/l); mild hyperglycaemia group (N=308, 16.6%), FPG≥ 7.1 to≤9.0 mmol/l (7–9 mmol/l); and severe hyperglycaemia group (N=291, 15.7%), FPG≥9.1 mmol/l. The primary end point was in-hospital and 3-year all-cause mortality from the day of admission.Results Compared with the euglycaemia group, hypoglycaemia or hyperglycaemia groups were all associated with higher in-hospital and 3-year all-cause mortality. There was a U-shaped relationship between admission FPG levels and short- and long-term all-cause mortality. This U-shaped relationship applied equally to subgroups in the context of contemporary treatments.Conclusions In older patients with AMI, increased as well as decreased admission FPG levels could predict higher in-hospital and 3-year mortality. There was a striking U-shaped relationship between admission FPG levels and short- and long-term mortality. An initial admission FPG level ≥ 5.1 to≤7.0 mmol/l may be desirable because it was associated with better clinical outcomes. ER -
