Cardiac ventricles release B-type natriuretic peptide (BNP) in response to volume expansion and pressure overload; therefore, BNP concentration may be used as a biochemical marker of cardiac failure (1). BNP levels are high in diabetic subjects with left ventricular dysfunction (2). Because the diagnosis of cardiac failure may be an emergency (3), it is important to know whether the timing of BNP measurement (before or after a meal) affects the result. The effect of renal failure is also an important practical issue, since 2540% of diabetic subjects have diabetic nephropathy. This
