Overview
Atrial fibrillation occurs in 1 to 20% of patients with acute coronary syndromes and is associated with a poorer prognosis.
Epidemiology and Demographics
Atrial fibrillation occurs in 1 to 20% (about 10%) of patients with acute coronary syndromes [1]
Risk Factors
Risk factors for the development of atrial fibrillation in the setting of ACS include:
- Female gender
- Older age
- Left ventricular dysfunction
Natural History, Complications, Prognosis
The occurrence of atrial fbrillation in the setting of acute coronary syndromes is associated with a poorer prognosis [2]:
- Any AF is associated with higher in hospital (OR 2.7), 30-day (OR 2.2), and 1-year mortality (OR 2.1) (p<0.001)
- New-onset AF was associated with higher in hospital (OR 5.2), 30-day (OR 3.9), and 1-year mortality (OR 3.1) (p<0.001)
