Interestingly, the present study combined four time points (28 days, 90 days, 180 days, and 1 year), and all four nodes consistently showed that high HRR was a protective factor independent of traditional variables in critical patients with HF, and the effect was strongest in the early stages and stabilized in the later stages, while high CAR was a persistent risk factor, with an increasing trend of adverse effects with follow-up time, which was a complementary relationship.
