Trends in cause-specific readmissions in heart failure with preserved vs. reduced and mid-range ejection fraction.

Declining temporal trend in HF readmission rates was found in HFpEF, but all-cause readmission still remained the highest in HFpEF vs. HFrEF and HFmrEF. More efforts are needed to reduce the non-HF-related readmission in patients with HFpEF.
