Abstract
This study aims to describe baseline characteristics and in-hospital management of a patient cohort hospitalized with acute heart failure (AHF). Adult patients in Denmark admitted with a medical diagnosis during a 7-day period were reviewed for symptoms and clinical findings suggestive of AHF. HFpEF was defined as LVEF ≥ 45%. Of 5194 patients, 290 (6%) had AHF. Sixty-two percent (n = 179) was diagnosed with HFpEF. Compared to HFrEF patients, HFpEF patients were more often women (48% vs. 31%, p = 0.004), less likely to have ischemic heart disease (31% vs. 53%, p = 0.002) and a pacemaker/ICD (7% vs. 21%, p < 0.001/1% vs. 8%, p < 0.001). Fewer HFpEF patients received intravenous diuretics (43% vs. 73%, p < 0.001) and inotropes (2% vs. 7%, p = 0.02), while more HFpEF patients received nitro-glycerine (59% vs. 44%, p = 0.02). Intubation/NIV, ICU admission, and revascularization were used similarly. Hospitalization was shorter for HFpEF patients (4 vs. 6 days, p < 0.001), with no significant difference in survival to discharge (96% vs. 91%, p = 0.07). Of AHF admissions, nearly two-thirds was due to HFpEF. Compared to HFrEF, HFpEF patients had a lower cardiac comorbidity and a 2-day shorter hospitalization.
