Name of journal: The American journal of medicineAbstract: BACKGROUND: A prior hospitalization due to heart failure is associated with poor outcomes in ambulatory patients with heart failure.

Overall, 927 and 1862 patients with HFpEF and HFrEF had heart failure hospitalizations during six months before the index hospitalization, respectively.

BACKGROUND: A prior hospitalization due to heart failure is associated with poor outcomes in ambulatory patients with heart failure. Less is known about this association in hospitalized patients with heart failure and whether it varies by ejection fraction.

CONCLUSIONS: Among hospitalized patients with heart failure, a prior heart failure hospitalization is associated with higher risks of mortality and readmission in both HFpEF and HFrEF. The relative risks of death and heart failure readmission appear to be higher in HFpEF than in HFrEF.
