ABSTRACT
BACKGROUND:
There are limited data regarding whether anemia is associated with adverse clinical outcomes in patients with atrial fibrillation (AF) after percutaneous coronary intervention (PCI).METHODS:
Patients with AF undergoing PCI at 15 institutions between January 2015 and March 2021 were included in this analysis. Based on the baseline hemoglobin levels, moderate to severe anemia was defined as hemoglobin levels <11 g/dL, and mild anemia was defined as hemoglobin levels 11-12.9 g/dL for men and 11-11.9 g/dL for women. Clinical outcomes within 1 year, including major adverse cardiovascular events (MACE all-cause death, myocardial infarction, stent thrombosis, and stroke) and major bleeding events (BARC 3 or 5), were compared among patients with moderate/severe anemia, mild anemia, and no anemia.RESULTS:
In a total of 746 enrolled patients, 119 (16.0%) and 168 (22.5%) patients presented with moderate/severe and mild anemia. The incidence of MACE (22.5%, 11.0%, and 9.1%, log-rank p < 0.001), all-cause death (20.0%, 7.2%, and 4.8%, log-rank p < 0.001), and major bleeding events (10.7%, 6.5%, and 2.7%, log-rank p < 0.001) were the highest in the moderate/severe anemia group compared with the mild and no anemia groups. Multivariable Cox regression analyses determined moderate/severe anemia as an independent predictor for MACE (p = 0.008), all-cause death (p = 0.005), and major bleeding events (p = 0.031) at 1 year after PCI.CONCLUSION:
Moderate/severe anemia was significantly associated with the higher incidence of MACE and all-cause death as well as major bleeding events compared with mild and no anemia in AF patients undergoing PCI.Key words
