Real‐world analysis of acute decompensated heart failure outcomes in Portugal

Abstract

Aims In Portugal, in the last 5 years, no study has published recent data regarding outcomes of patients with acute decompensated heart failure (ADHF). We aimed to determine the characteristics and outcomes of a large contemporaneous Portuguese cohort of ADHF patients admitted to our emergency department (ED). Methods and resultsWe conducted a retrospective, study of all 1024 patients admitted to our ED with a discharge diagnosis of ADHF from November 2016 to December 2017. Baseline clinical data and outcomes {in-hospital, 30 day, and follow-up allcause mortality, and readmissions; median follow-up, 5 months; interquartile range [(IQR), 3-11 months]} were determined. Mean age was 78 ± 10 years, and 53% were male; of the 1024 patients, 554 (54%) were hospitalized. The median hospitalization length was 9 (IQR, 5-15) days, and in-hospital mortality was 12.7%. Hospitalized patients were predominantly men (56% vs. 47%; P < 0.001), younger (77 ± 9 vs. 79 ± 11 years; P = 0.002) and had higher creatinine values and B-type natriuretic peptide values (P < 0.001) than discharged patients. Patients with prior hospitalization had lower 30 day readmission rate (8% vs. 14%; P = 0.01), same overall readmission rate (30% vs. 32%), and higher 30 day (13% vs. 5%; P < 0.001) and overall mortality rates (28% vs. 15%; P < 0.001). Conclusions Approximately half of the patients admitted to the ED were hospitalized. Of these, only 8% were readmitted in the ED within 30 days. The clinical and analytical status in the ED are important predictors of hospitalization.Additional supporting information may be found online in the Supporting Information section at the end of the article.

Acute heart failure and iron deficiency: a prospective, multicentre, observational study

“…The age and sex in our study sample are comparable with those in other observational studies reporting real-world data of AHF patients. 33,34 We therefore are convinced that our study population can be considered as a real-life cohort.…”

Association between echocardiographic markers of pulmonary hypertension and short-term prognoses in patients with acute heart failure

“…At the same time, in patients with recent chronic heart failure, non-adherence to drug treatment, valvular disorders, and infections are the primary triggers for uncompensated heart failure (6). Heart failure symptoms and signs usually appear suddenly or progress rapidly and require immediate hospitalization (7). Acute decompensated heart failure is one of the leading causes of hospitalization and mortality in patients over 65 years of age (8).…”
