Comparing efficacy of receiving different dosages of eptifibatide in bleeding after percutaneous coronary intervention in patients with myocardial infarction

BACKGROUND: Acute coronary syndrome (ACS) is a common condition that needs appropriate treatment like percutaneous coronary intervention (PCI). Glycoprotein IIb/IIIa inhibitors (GPI) like eptifibatide prevent procedural ischemic complications after PCI. Eptifibatide has increased the risk of bleeding complications, although it is effective in reducing mortality and morbidity. Eptifibatide is routinely used in bolus and infusion forms and the aim of this study is to evaluate the efficacy of bolus-only dose and bolus + infusion strategy for administrating eptifibatide in bleeding complications and consequences after PCI.METHODS: This randomized clinical trial was conducted on subjects who experienced PCI after incidence of myocardial infarction (MI). Patients were randomly divided into two groups who received bolus-only dose (n = ۵۱) or bolus + infusion form of eptifibatide (n = ۵۰). Then, PCI blood pressure, mean time duration of hemostasis after arterial sheath removal, laboratory data, need for blood transfusion, and presence of bleeding complications were evaluated. After ۶ months, patients were followed for needs for additional coronary interventions.RESULTS: The mean age of participants was ۶۱.۶۸ ± ۱.۵۰ years. The prevalence of men was ۷۰.۲۹%. There was no significant difference in mean of systolic blood pressure (SBP) and diastolic blood pressure (DBP) during hospitalization (P > ۰.۰۵۰). The mean time duration of hemostasis was ۸.۱۳ ± ۰.۴۵ minutes in the bolus-only group and ۱۶.۴۶ ± ۰.۷۱ minutes in the bolus + infusion group (P < ۰.۰۰۱). There was no significant difference in the hemoglobin (Hb) level, platelet count, white blood cell (WBC), blood urea nitrogen (BUN), and creatinine level (P > ۰.۰۵۰).CONCLUSION: The results of this study suggested that bolus-only dose of eptifibatide before PCI could be able to decrease significantly bleeding complication and other clinical and cardiovascular outcomes.
