Insights
Patients hospitalized for heart failure (HF) with abnormal left ventricular ejection fraction (LVEF) had higher in-hospital mortality. However, hospitalization duration and discharge functional class were similar regardless of LVEF status.
Area of Science:
- Cardiology
- Internal Medicine
- Clinical Research
Background:
- Heart failure (HF) is a complex clinical syndrome.
- Left ventricular ejection fraction (LVEF) is a key metric in HF classification.
- Understanding outcomes based on LVEF is crucial for patient management.
Purpose of the Study:
- To compare clinical outcomes in hospitalized patients with heart failure (HF) based on left ventricular ejection fraction (LVEF) status.
- To analyze the impact of abnormal versus normal LVEF on mortality, hospitalization duration, and functional status.
Main Methods:
- Prospective investigation of 200 consecutive hospitalized heart failure patients.
- Categorization into two groups: abnormal LVEF (n=100) and normal LVEF (n=100).
- Comparison of in-hospital mortality, length of stay, and New York Heart Association (NYHA) class at discharge.
Main Results:
- In-hospital mortality was significantly higher in the abnormal LVEF group compared to the normal LVEF group.
- The duration of hospitalization was similar between patients with abnormal LVEF and normal LVEF.
- New York Heart Association (NYHA) functional class at discharge did not differ significantly between the two LVEF groups.
Conclusions:
- While abnormal LVEF is associated with increased mortality risk in hospitalized heart failure patients, it does not appear to influence hospitalization length or functional recovery at discharge.
- Clinical management strategies should consider the heightened mortality risk in HF patients with reduced LVEF.
- Further research may explore specific interventions to mitigate mortality in this subgroup.
Abstract:
We investigated treatment of 200 consecutive patients hospitalized for heart failure (HF). Of the 200 patients, 100 (50%) had an abnormal left ventricular ejection fraction (LVEF) and 100 (50%) had a normal LVEF. Although in-hospital mortality was significantly increased in patients with HF and an abnormal LVEF, the duration of hospitalization and the NYHA class at discharge were similar in patients with HF and abnormal or normal LVEF.
