A progressive relationship between hemoglobin A(1c) (HbA(1c)) levels and cardiovascular (CV) events has been observed in persons with and without diabetes. To our knowledge, the nature of such a relationship in patients with symptomatic chronic heart failure (HF) has not been studied. ⋯ In diabetic and nondiabetic patients with symptomatic chronic HF, the HbA(1c) level is an independent progressive risk factor for CV death, hospitalization for HF, and total mortality.
