title: Hyperglycemia in acute heart failure: an opportunity to intervene?
abstract: In patients with acute heart failure (AHF) syndromes, little data are so far available on the relation between glucose values and insulin resistance and mortality, both in the short and long term. The present review is aimed at summarizing available evidence on the prognostic role of hyperglycemia in acute heart failure syndromes. Despite the fact that glucose values are widely measured, inexpensive, and easy to interpret, hyperglycemia in AHF patients still appears to be (or at least to have been) a neglected factor. Scarce information is available on incidence of admission hyperglycemia (especially in nondiabetic AHF patients) and data on in-hospital and discharge glucose values are lacking. Overall, the scarcity of data and the unanswered questions conjure up the need for trials investigating the clinical and prognostic role of glucose abnormalities (hyperglycemia and acute insulin resistance) on admission and during hospital stay in AHF patients. Preliminary evidence suggests that hyperglycemia is an important prognostic factor in AHF; however, whether targeting hyperglycemia via an aggressive versus permissive glycemic management strategy influences AHF outcomes remains unknown.
