ABSTRACT
OBJECTIVE:
Aspirin-induced enteropathy is increasing, but whether the type of aspirin affects the gastrointestinal (GI) bleeding, especially small intestine, is unclear. The incidence of GI bleeding for buffered aspirin and enteric-coated aspirin was evaluated in patients receiving long-term low-dose aspirin (LDA) for cardiovascular (CV) diseases.METHODS:
This retrospective cohort study assessed overt GI bleeding, decreased hemoglobin levels suspecting small bowel blood loss, and CV death in patients taking LDA for more than 1 year (LDA group) and in patients not taking LDA (control group). The LDA group was divided into two subgroups, patients taking either buffered aspirin (buffered subgroup) or enteric-coated aspirin (enteric subgroup), and their outcomes were compared.RESULTS:
A total of 1402 patients (LDA group 701, control group 701; median follow-up duration 1778 ± 747 days) were assessed. The incidences of overt GI bleeding and decreased hemoglobin were 3.9% and 1.4% in LDA group, respectively, significantly higher than the control group (p < 0.01; p < 0.01). In the LDA group, 3% died during the follow-up period. Ten (3.7%) in the buffered subgroup (n = 267) and 17 (3.9%) in the enteric subgroup (n = 434) developed GI bleeding (p = 0.92). One (0.3%) in the buffered subgroup and nine (2%) in the enteric subgroup developed decreased hemoglobin (p = 0.06, log-rank test).CONCLUSIONS:
The type of aspirin does not affect the incidence of overt GI bleeding and decreased hemoglobin, but enteric-coated aspirin may be associated with an increased incidence of decreased hemoglobin.
