|概要||INTRODUCTION: DAPT score with cut‒off value of 2‒point is reported to have clinical benefits in predicting thrombotic and bleeding events after percutaneous coronary intervention (PCI). However, there has been little report testing the impact of DAPT score on hemodialysis patients as the highest‒risk population.
METHODS: This study included 239 consecutive hemodialysis patients receiving P2Y12‒inhibitors and aspirin for at least 12 months after PCI. DAPT score was graded from ‒2 to 10 points at the time of PCI. During follow‒up period of 730 days, the incidences of cardiovascular (CV) death, major adverse cardiac events (MACE) including CV death, target vascular revascularization and non‒fatal myocardial infarction (MI), and major bleeding were compared between high‒DAPT patients (score ≥2, n=146) and low‒DAPT patients (score <2,n=93).
RESULTS: High‒DAPT group included younger diabetic patients with impaired left ventricular ejection fraction, compared to low‒DAPT group. Prior ischemic event rates were similar in both groups. Kaplan‒Meier analysis revealed that any adverse event rates had no significant difference between the groups (2‒year CV death: 10.8% vs. 14.3%; MACE: 47.0% vs. 39.7%; major bleeding: 8.0% vs. 9.0%). Furthermore, any other cut‒off points from ‒1 to 7 could not make significant difference in clinical event rates.
CONCLUSION: In hemodialysis patients, DAPT score is hardly adapted in predicting clinical adverse events, and in determining who should receive prolonged dual antiplatelet therapy.
