Fasting glucose, NT-proBNP, treatment with eptifibatide, and outcomes in non-ST-segment elevation acute coronary syndromes: An analysis from EARLY ACS.


Conference Paper

BACKGROUND: Higher N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels have been linked to a more favorable glucometabolic profile. Little is known about the interaction of NT-proBNP and fasting glucose in non-ST-segment elevation acute coronary syndrome (NSTE ACS). METHODS: Fasting glucose and NT-proBNP were measured in 2240 patients enrolled in the EARLY ACS trial. Multivariable Cox models were used to assess associations between fasting glucose and NT-proBNP and a 96-hour composite of death, myocardial infarction (MI), recurrent ischemia, or thrombotic bailout; 30-day death or MI; and 1-year mortality. RESULTS: In adjusted Cox models, neither NT-proBNP nor fasting glucose was associated with the 96-hour endpoint (p=0.95 and p=0.87). NT-proBNP was associated with 30-day death or MI (hazard ratio [HR] 1.11, 95% confidence interval [CI] 1.02-1.22, p=0.02) and 1-year mortality (HR 1.63, 95% CI 1.42-1.89, p<0.0001), but fasting glucose was associated only with 1-year death (HR 1.53, 95% CI 1.08-2.16, p=0.02). NT-proBNP×glucose interaction terms were non-significant in all models. As fasting glucose levels increased, the risk of 96-hour and 30-day endpoints increased among patients who received early eptifibatide but not delayed, provisional use (pint=0.035 and pint=0.029). Higher NT-proBNP levels were associated with greater 30-day death or MI among patients who received early eptifibatide but not delayed, provisional use (pint=0.045). CONCLUSION: NT-proBNP and fasting glucose concentrations were associated with intermediate-term ischemic outcomes and may identify differential response to treatment with eptifibatide.
