  • Systematic review and meta-analysis of randomised controlled trials
  • prespecified subgroup analyses

Authors' conclusion

In patients with ACS undergoing PCI, ultrashort DAPT reduced bleeding without increasing ischemic events overall, although a signal of increased MACCE was observed in STEMI but not in NSTE-ACS.

Study context

Population
Patients with acute coronary syndrome (ACS) undergoing PCI
Participants
29,232 patients · 10 trials
Comparison
Ultrashort dual antiplatelet therapy (DAPT) vs standard-duration DAPT
Outcome
MACCE, major bleeding and net adverse clinical event (NACE)

Pooled result

As reported in the abstract

Ultrashort DAPT vs Standard-duration DAPTHazard ratio (95% CI)P value
MACCE; I2 = 24%
1.06(0.93–1.20)
P = 0.38
major bleeding; I2 = 44%
0.47(0.35–0.64)
P < 0.00001
NACE (net clinical benefit); I2 = 61%
0.83(0.72–0.97)
P = 0.02

Further pooled results

Major adverse cardiac and cerebrovascular events (MACCE) by ACS type (subgroup)

Higher MACCE risk with ultrashort DAPT in STEMI but not NSTE-ACS

Major bleeding by ethnicity (prespecified subgroup)

East Asians: HR 0.35 (95% CI 0.25-0.49), P < 0.00001, I2 = 0%
Non-East Asians: HR 0.63 (95% CI 0.43-0.93), P = 0.02, I2 = 44%
  • interaction P = 0.02

MACCE by abbreviation strategy (prespecified subgroup)

Intensive abbreviation (≤1-week DAPT or clopidogrel/aspirin monotherapy): HR 1.37 (95% CI 1.11-1.69), P = 0.003, I2 = 0%
Moderate abbreviation (≥2-week DAPT, then ticagrelor/prasugrel monotherapy): HR 0.96 (95% CI 0.85-1.08), P = 0.47, I2 = 0%
  • P for interaction = 0.003
