What’s the right duration of dual antiplatelet therapy (DAPT) for patients who have had drug-eluting stents implanted? According to researchers from Sungkyunkwan University in Seoul, Korea, long-term clinical outcomes are similar whether patients receive therapy for less than or longer than 12 months.
The researchers conducted a retrospective study of 512 patients who had undergone percutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO) and were event free at 12 months. They separated the patients into 2 groups: 199 received aspirin and clopidogrel for ≤ 12 months, and 313 for > 12 months. The primary outcome was major adverse cardiac and cerebrovascular event (MACCE) during follow-up. Median follow-up was 64 months.

No significant differences were seen between the groups in the incidence of MACCE: 21.6% of the patients in the ≤ 12-month group and 17.6% of the patients in the > 12-month group developed MACCE. After propensity matching, moderate or severe bleeding rates were also similar (1.6% in the shorter duration group and 2.2% in the longer duration group).
The researchers note that previously published data showed that longer duration DAPT was not associated with improved clinical outcomes in patients with CTO, although other subsets of complex PCI, such as longer stent length, bifurcation stenting, or multiple stents showed better clinical outcomes. To the best of their knowledge, the researchers add, theirs is the first study to directly compare DAPT durations in patients with CTO-PCI.
