NPPB and heart failure: The primary findings of the present study are as follows1: regarding clinical outcomes, the incidence of MACE was higher in the CMD group than in the non‐CMD group; this was primarily owing to a higher incidence of heart failure readmission2; multivariate Cox regression analysis revealed that AMR ≥ 250, age, troponin I detection peak, and BNP were independent risk factors for 1‐year MACE occurrence.
