Hospitalization of patients with heart failure: a population-based study

Area of Science:

• Cardiology
• Public Health
• Clinical Medicine

Background:

• Heart failure (HF) is a major cause of morbidity and mortality.
• Understanding the clinical course of incident HF is crucial for effective management.
• Population-based data on HF prognosis is essential for public health planning.

Purpose of the Study:

• To characterize the clinical trajectory of heart failure in a population-based cohort.
• To identify predictors of hospitalization and mortality in incident heart failure cases.

Main Methods:

• Prospective, population-based study of incident heart failure cases.
• Data collection on hospitalizations, mortality, and clinical factors over 15 months.
• Statistical analysis to identify predictors of adverse outcomes.

Main Results:

• 332 incident HF cases identified; 208 inpatients, 124 outpatients.
• 18% case fatality during initial hospitalization; 173 cases (59%) rehospitalized over follow-up.
• Inpatient diagnosis associated with higher readmission rates (26 more admissions/100 cases) and mortality (HR 3.1).
• Age predicted hospitalization; age, functional class, and creatinine predicted mortality.

Conclusions:

• Incident heart failure patients are at significant risk of subsequent hospitalizations, especially early post-diagnosis.
• Predicting individual hospitalization risk remains challenging.
• Targeted interventions for elderly inpatients with new heart failure diagnoses are recommended to reduce hospitalizations.
