In order to present the results of model C more clearly, we stratified patients according to their NT-proBNP median and assessed the impact of the DES-generation on the risk of death in different stages of HF: Out of 170 patients with NT-proBNP levels above median 89 patients underwent PCI with first-generation DES and 81 patients underwent PCI with newer-generation DES. Here, NPPB is linked to hydrops fetalis.
