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<0.001) and more likely to be female (42% vs 34%, p<0.001) or white (85% vs 78%; p<0.001). Hypertension, renal failure, diabetes mellitus and congestive heart failure were all more prevalent among those with AF (p<0.001 for all). 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<0.001) and an increased risk of bleeding complications after both PCI (12.2% vs 5.3%; OR: 1.18; CI: 1.16-1.21; p<0.001) and CABG (40.0% VS 33.5%; OR: 1.11; CI: 1.08-1.13; p<0.001). Average length of stay was also longer among those with AF (7 days vs 4 days; p<0.001).
Conclusion: AF which is common in patients presenting with STEMI is independently associated with increased risk of all-cause in-hospital mortality and complications
