Height (β = −0.301, p = 0.036), body weight (β = −0.359, p = 0.011), BMI (β = −2.94, p = 0.038), triglyceride (β = −0.286, p = 0.046), and HOMA-IR (β = −0.346, p = 0.015) were negatively correlated with plasma Nt-proBNP levels among the CHF patients. Here, NPPB is linked to congestive heart failure.
