Multicenter Study Observational Study
Perioperative management of oral antiplatelet therapy and clinical outcomes in coronary stent patients undergoing surgery. Results of a multicentre registry.
The aim was to investigate the perioperative risk of ischaemic and bleeding events in patients with coronary stents undergoing cardiac and non-cardiac surgery and how these outcomes are affected by the perioperative use of oral antiplatelet therapy. This was a multicentre, retrospective, observational study conducted in patients with coronary stent(s) undergoing cardiac or non-cardiac surgery. The primary efficacy endpoint was the 30-day incidence of major adverse cardiac events (MACE), defined as the composite of cardiac death, myocardial infarction (MI) or stroke. ⋯ The overall incidence of BARC ≥ 2 bleeding events at 30-days was significantly higher in patients who discontinued oral antiplatelet therapy (25.6 % vs 13.9 %, p< 0.001). However, after adjustment, antiplatelet discontinuation was not independently associated with BARC ≥ 2 bleeding. In conclusion antiplatelet discontinuation increases the 30-day risk of MACE, in patients with coronary stents undergoing cardiac and non-cardiac surgery, while not offering significant protection from BARC≥ 2 bleeding.
