Abstract

Although an increasing number of patients accept dual antiplatelet therapy (DAPT) following implantation of drug-eluting stents (DES) for coronary heart disease (CHD), the proportion of patients with DAPT who subsequently develop gastrointestinal hemorrhage continues to increase. To ensure the clinical outcomes from DES, it is important to formulate a novel continued antiplatelet therapy for patients who were administered DAPT and subsequently develop gastrointestinal hemorrhage following DES implantation. The present study aimed to evaluate the effects of continued aspirin, clopidogrel or DAPT use on the incidence of clinical adverse events and gastrointestinal rebleeding in patients who received DAPT and subsequently developed gastrointestinal hemorrhage following implantation of DES for CHD. Between 2004 and 2010, 108 consecutive patients receiving DAPT developed gastrointestinal hemorrhage following DES implantation for CHD at Liuzhou General Hospital (Liuzhou, Guangxi). These patients were divided into three groups according to the novel antiplatelet therapy. The occurrence of major adverse cardiac events (MACE), including cardiac death, non‑fatal myocardial infarction, heart failure or target vessel revascularization, net adverse clinical events (NACE), including major bleeding, stroke or MACE, and gastrointestinal rebleeding during clinical follow‑up following the initial procedure were compared among these three groups. The results of this analysis demonstrated that the occurrence rate of MACE, NECE and gastrointestinal rebleeding was not significantly different among these groups (P>0.05). Furthermore, survival analysis was performed and although the survival curves of MACE and NECE were not significantly different among these groups, gastrointestinal rebleeding was demonstrated to be significantly different among the three groups (P<0.05), and continued aspirin or clopidogrel use was superior to continued DAPT. In conclusion, the results of the present study indicated that there were no significant differences in the clinical effectiveness and safety of continuing antiplatelet monotherapy or DAPT in patients who are administered DAPT and experience gastrointestinal hemorrhage following DES implantation. As for the prevention of recurrent bleeding, antiplatelet monotherapy was demonstrated to be superior to DAPT. Moreover, the treatment of patients who are administered DAPT and experience gastrointestinal hemorrhage following DES implantation must involve an evaluation of the risk of complications, including stent thrombosis, continuous bleeding and recurrent hemorrhage.
