Insights
Hospitalized heart failure in Japan affects many elderly patients, often with hypertension. This study analyzed 4,842 patients, revealing long hospital stays and high mortality, necessitating improved prevention and treatment strategies.
Area of Science:
- Cardiology
- Public Health
- Clinical Research
Background:
- Hospitalized heart failure (HHF) presents a significant challenge in Japan.
- Improving HHF management and outcomes requires analysis of clinical features, in-hospital care, and patient results.
Purpose of the Study:
- To analyze the clinical features, in-hospital management, and outcomes of patients with hospitalized heart failure in Japan.
- To inform and improve clinical guidelines for HHF management.
Main Methods:
- Utilized data from the Acute Decompensated Heart Failure Syndromes (ATTEND) registry, the largest study of HHF in Japan.
- Included 4,842 enrolled patients, focusing on clinical characteristics and in-hospital treatment.
Main Results:
- The study population consisted primarily of elderly patients with new-onset heart failure, often with a history of hypertension and orthopnea.
- Common treatments included furosemide and carperitide, with a mean length of stay of 30 days and an in-hospital mortality rate of 6.4%.
Conclusions:
- Primary prevention of HHF is crucial for elderly hypertensive and diabetic patients.
- Intensified management, including noninvasive positive pressure ventilation, is recommended during the acute phase.
- Further research is needed to clarify the clinical benefits of carperitide and angiotensin-receptor blockers in the Japanese HHF population.
- The relationship between length of stay and in-hospital mortality, considering both outcomes and costs, requires further investigation.
Background:
Hospitalized heart failure (HHF) is a critical issue in Japan. To improve its management and outcomes, the clinical features, in-hospital management, and outcomes should be analyzed to improve the guidelines for HHF.
Methods And Results:
The acute decompensated heart failure syndromes (ATTEND) registry is the largest study of HHF in Japan. The present report covers the clinical features and in-hospital management of HHF patients. The data from 4,842 enrolled patients have demonstrated that most Japanese HHF patients are elderly, with new onset, and a history of hypertension and orthopnea on admission. During hospitalization, furosemide and carperitide were commonly used and the length of stay was extremely long (mean 30 days), with 6.4% in-hospital mortality.
Conclusions:
The findings of the present study suggest the following: (1) the focus for hypertensive elderly and diabetic patients should be on primary prevention of HHF,(2) more intensive management with noninvasive positive pressure ventilation should be performed at the urgent stage, (3) it is necessary to clarify the clinical benefit of carperitide and angiotensin-receptor blockers, because they are commonly used in Japan, and (4) it is necessary to clarify the relationship between in-hospital mortality and length of stay from the viewpoint of both outcome and cost of patient care.
