Statin treatment is associated with a negative correlation between NT-proBNP and insulin resistance in patients without history of heart failure.

Abstract

BACKGROUND We investigated the effect of statin treatment on the relationship between N-terminal pro-B-type natriuretic peptide (NT-proBNP) and insulin resistance in patients without history of heart failure. METHODS Patients without history of heart failure and diabetes were recruited to undergo an oral glucose tolerance test. Blood samples were collected for measurements of NT-proBNP, glucose, and insulin. Insulin resistance was assessed using the homeostasis model assessment of insulin resistance (HOMA-IR). Linear mixed model analysis was used to examine the correlation between NT-proBNP and HOMA-IR. RESULTS A total of 219 patients (mean age 61.1±11.8y, median NT-proBNP 64.3 [32.1-154.5] pg/ml) were analyzed. Overall, NT-proBNP was negatively correlated with HOMA-IR after an adjustment for confounders (β coefficient -0.335, 95% CI [-0.516, -0.153], p=0.001). This correlation was significant in patients on statin treatment (n=91, β coefficient -0.558, 95% CI [-0.802, -0.312], p<0.001), but was insignificant in patients not on statin treatment (n=128, β coefficient -0.147, 95% CI [-0.412, 0.118], p=0.274, p for interaction=0.040). CONCLUSIONS Statin treatment is associated with a negative correlation between NT-proBNP and insulin resistance in patients without history of heart failure. Our findings suggest that NT-proBNP may be related to insulin resistance associated with statin treatment.
