Atrial fibrillation (AF) increases mortality and hospitalization, often coexisting with heart failure and acute coronary syndromes. Understanding these complex non-embolic outcomes is crucial for better patient management.
Area of Science:
- Cardiology
- Electrophysiology
- Internal Medicine
Background:
- Atrial fibrillation (AF) is a prevalent arrhythmia with well-established embolic risks managed by anti-platelet/anticoagulant therapies.
- Emerging evidence highlights significant associations between AF and non-embolic adverse outcomes.
Purpose of the Study:
- To review the complex relationship between atrial fibrillation and non-embolic complications.
- To emphasize the impact of AF on mortality, heart failure, and other cardiovascular events.
Main Methods:
- Literature review of observational cohorts and clinical trial data.
- Analysis of studies investigating AF's association with mortality, heart failure, acute coronary syndromes, and hospitalizations.
Main Results:
- AF is linked to a 1.5 to 2-fold increase in mortality and a 1.5 to 3-fold increase in hospitalization rates.
- AF presence worsens outcomes in patients with heart failure and acute coronary syndromes.
- AF is associated with increased risk of other arrhythmias, including bradyarrhythmias and tachyarrhythmias.
Conclusions:
- Atrial fibrillation contributes significantly to morbidity, mortality, and healthcare costs beyond embolic events.
- Refined risk stratification and pharmacotherapeutic strategies are essential to mitigate the growing burden of AF.
