ABSTRACT
BACKGROUND:
Whether the efficacy and safety of dual antiplatelet therapy (DAPT) are uniform between sexes is unclear. We sought to compare clinical outcomes between short- (≤6 months) versus long-term (≥1 year) DAPT after drug-eluting stent (DES) placement in women and men. METHODS ANDRESULTS:
We pooled individual patient data from 6 randomized trials of DAPT (EXCELLENT, OPTIMIZE, PRODIGY, RESET, SECURITY, ITALIC PLUS). The primary outcome was 1-year risk of major adverse cardiac events (MACE). The main secondary outcome was 1-year risk of any bleeding. Out of the 11,473 randomized patients included in the pooled dataset, 3,454 (30%) were females. At 1-year follow-up, women had higher risk of MACE (3.6% vs. 2.8%; P = 0.01) but similar risk of bleeding (1.9% vs. 1.6%; P = 0.16) as compared with men. Compared with long-term DAPT, short-term DAPT was associated with similar rates of MACE in both women (HR 0.88; 95% CI 0.62-1.25) and men (HR 1.25; 95% CI 0.95-1.6; P interaction = 0.08)]. At 1-year follow-up, short-term DAPT was associated with lower rates of bleeding as compared with long-term DAPT in both women (HR 0.84; 95% CI 0.51-1.37) and men (HR 0.58; 95% CI 0.40-0.84; P-interaction = 0.25). The presence of MVD was associated with higher MACE rates in the short-term DAPT group in women (HR 1.16; CI 0.60-2.23) and men (HR 2.29; CI 1.22-4.29; P interaction = 0.25).CONCLUSIONS:
Short-term DAPT is associated with similar rates of MACE but lower risk of bleeding when as compared with prolonged DAPT. There was no significant difference between sexes in the population studied. © 2016 Wiley Periodicals, Inc.Palavras-chave
