Abstract

Introduction: Current guidelines recommend continuation of dual anti-platelet therapy (DAPT) for 12 months after percutaneous coronary intervention (PCI). Recent studies have shown benefit in continuing DAPT beyond 12 months but at the risk of increase bleeding. To date, there has been little data on risk stratifying patients to determine who can continue DAPT beyond 12 months at minimal bleeding risk. Methods: All patients who underwent drug-eluting stent (DES) placement from January 1, 2013 to September 30, 2014 were reviewed. Patients who had follow-up for at least 12 months, placement of 2nd generation everolimus-coated DES, and were on DAPT for at least 12 months were included. Patients with a history of atrial fibrillation, follow-up time less than 12 months, or were on concurrent oral anticoagulation therapy were excluded. Results: Five hundred thirty-one patients were analyzed as described above. Two hundred two patients included in our study with 7 patients in the bleeding cohort and 195 patients in no-bleed cohort. The HAS-BLED score in patients who had a bleeding episode vs. those who did not was 3.29 vs. 2.24 (P value of 0.0009). Although not statistically significant, patients who had a bleeding episode were more likely to have renal dysfunction, alcohol use, be on prasugrel, and be on 325mg of aspirin. Conclusion: The study shows that the HAS-BLED score can be of utility in risk stratifying patients in determining who can continue DAPT beyond 12 months. Furthermore, a HAS-BLED score of less than 2 may help guide extended DAPT beyond 12 months at minimal bleeding risk.
