Usefulness of hyperglycemia in predicting renal and myocardial injury in patients with diabetes mellitus undergoing percutaneous coronary intervention.

A retrospective analysis of 165 patients who had diabetes mellitus and underwent percutaneous coronary intervention (PCI) between 1998 and 2003 demonstrated that those whose plasma glucose levels were >/=200 mg/dl before PCI exhibited greater creatine phosphokinase release and serum creatinine increases after PCI. These observations identified hyperglycemia as a potentially modifiable mediator of myocardial and renal injuries in patients who have diabetes and have undergone PCI.
