Background: Atrial fibrillation (AF) is reported in 7-19% patients with acute ST- Segment Elevation Myocardial Infarction (STEMI). There is
a paucity of data on the impact of AF on outcomes in patients with acute STEMI.
Methods: We queried the National Inpatient Sample (NIS) database for years 2003- 2013 to identify all patients >=18 years of age
admitted with acute STEMI.
Results: Of the total 2,632,447 STEMI hospitalizations, AF was documented in 339,987 (12.9%) patients. At baseline, patients with
AF were older (mean 74 vs 63 years, p
Hypertension, renal failure, diabetes mellitus and congestive heart failure were all more prevalent among those with AF (p
AF patients were more likely to undergo surgical but less likely to undergo percutaneous revascularization than non-AF patients (Table 1).
Patients with AF had higher risk adjusted in- hospital mortality (16.3% vs 7.9%; OR: 1.16; CI: 1.15-1.18; p
bleeding complications after both PCI (12.2% vs 5.3%; OR: 1.18; CI: 1.16-1.21; p
Conclusion: AF which is common in patients presenting with STEMI is independently associated with increased risk of all-cause in-hospital mortality and complications
