Aim: To assess the prevalence, risk and management of hyperglycemia in patients with acute coronary syndrome (ACS). Methods and Results: Design: a multicenter prospective observational study of a representative sample of patients with ACS consecutively admitted to intensive cardiac care units (ICCU).Setting: 31 out of 61 ICCUs in Lombardy, the most heavily populated Italian region.From May 2009 to April 2010 1260 patients (69.4% male; mean age 68 ± 13 years) were included in the study: 301 (23.9%) were known diabetic patients (D) and 265 (21.0%) had hyperglycemia (H) (blood glucose >180 mg/dL) at hospital admission, 174 with a history of diabetes (D+H+) and 91 without (D-H+). On the first day after admission intravenous insulin infusion was prescribed to 72 D+H+ (41.4%) and 10 D-H+ (11.0%), according to different protocols. Approximately one third of D+H+ patients (59) and one fifth (17) of D-H+ maintained mean blood glucose higher than 180 mg/dL during the first day in the ICCU.Patients with diabetes or hyperglycemia had a higher incidence of major adverse cardiovascular events or death in hospital. However, at multivariable analysis neither diabetes nor blood glucose at admission was associated with a poor prognosis whereas mean blood glucose on the first day was an independent negative prognostic predictor (OR 1.010, 95% CI 1.002-1.018, p = 0.016). Conclusion: Hyperglycemia is frequent in patients with ACS and is independently associated with a poor in-hospital prognosis if it persists in first day. Unfortunately, however, this condition is still poorly treated, with far from optimal blood glucose control. © 2015 Elsevier B.V.
