Hyperglycemia During Acute Coronary Syndrome: Prognostic Implications

The adverse prognostic impact of hyperglycemia in patients with critical illness has focused considerable attention from expert groups and professional societies. In particular, an association between hyperglycemia and increased mortality and in-hospital complications in the time of acute coronary syndromes (ACS) has been confirmed in different studies [4,5]. In this setting, prevalence of hyperglycemia ranges from 3% to 71% according to different threshold of blood glucose used for diagnosis [4]. The lowest prevalence is observed with serum glucose levels of 169-306 mg/dl while, as expected, lower thresholds for diagnosing new hyperglycemia (108 mg/dl) is associated with the highest prevalence [4].
