Authors' conclusion

1-month DAPT may offer the lowest risk balance between ischaemic and bleeding risks; however, these findings should be applied within an individualised, patient-specific risk management framework.

Study context

Population
Patients with ischaemic heart disease
Participants
95,910 patients · 31 randomised controlled trials
Comparison
Dual antiplatelet therapy (DAPT) durations of 1 month, 3 months, 6 months, 12 months and >12 months
Outcome
Net adverse clinical events (NACE), a composite of death, myocardial infarction, stroke, stent thrombosis and bleeding events

Pooled result

As reported in the abstract

No significant differences in death, myocardial infarction, stroke or stent thrombosis with 1-month DAPT, except myocardial infarction vs >12 month DAPT
