Supports graded HF risk with higher-normal glucose in nondiabetics; hypothesis-generating and requires prospective trials before practice implications.
Does higher baseline blood glucose increase the incidence of heart failure in nondiabetic patients?
Higher baseline blood glucose levels, even within the nondiabetic range, are independently associated with a significantly increased risk of developing heart failure.
