Background |
Optimal dual antiplatelet therapy (DAPT) duration in patients at high bleeding risk (HBR) is not fully defined. We aimed to compare the safety and effectiveness of short-term DAPT (S-DAPT) with longer duration DAPT (L-DAPT) after percutaneous coronary intervention (PCI) with drug eluting stents (DES) in patients at HBR.
Methods |
We searched for studies comparing S-DAPT (≤3 months) followed by aspirin or P2Y 12 inhibitor monotherapy against L-DAPT (6-12 months) after PCI in HBR patients. Primary end points of interest were major bleeding and myocardial infarction (MI). Random-effects meta-analyses were performed to calculate odds ratios with 95% CIs.
Results |
Six randomized trials and 3 propensity-matched studies (n = 16,848) were included in the primary analysis. Compared with L-DAPT (n = 8,422), major bleeding was lower with S-DAPT (n = 8,426) [OR 0.68; 95% CI 0.51-0.89] whereas MI did not differ significantly between the 2 groups [1.16; 0.94-1.44]. There were no significant differences in risks of death, stroke or stent thrombosis (ST) between S-DAPT and L-DAPT groups. These findings were consistent when propensity-matched studies were analysed separately. Finally, there was a numerically higher, albeit statistically non-significant, ST in the S-DAPT arm of patients without an indication for OAC [1.98; 0.86-4.58].
Conclusions |
Among HBR patients undergoing current generation DES implantation, S-DAPT reduces bleeding without an increased risk of death or MI compared with L-DAPT. More research is needed to (1) evaluate risks of late ST after 1 to 3 months DAPT among patients with high ischemic and bleeding risks, (2) defining the SAPT of choice after 1 to 3 months DAPT.

| We aimed to compare short-term dual antiplatelet therapy (S-DAPT) with longer duration DAPT (L-DAPT) after drug eluting stents (DES) implantation in patients at high bleeding risk (HBR). Compared with L-DAPT, the odds of major bleeding were lower with S-DAPT [OR 0.63; 95% CI 0.44-0.90] whereas MI did not differ significantly between the 2 groups [1.31; 0.96-1.80]. There were no significant differences in risks of all-cause death, CV death or MI between S-DAPT and L-DAPT. In conclusion, among HBR patients undergoing current generation DES implantation, S-DAPT reduces bleeding without an increased risk of death or MI compared with L-DAPT. |
