Insights

For coronary artery bypass graft surgery (CABG), stop aspirin 7-10 days and clopidogrel 5 days before. Resume aspirin 48 hours post-surgery to prevent clots and bleeding.

Area of Science:

  • Cardiology
  • Vascular Surgery
  • Pharmacology

Background:

  • Antiplatelet therapy is crucial for coronary artery disease management.
  • Optimal use of antiplatelet agents around coronary artery bypass graft surgery (CABG) remains debated.
  • Key concerns include preoperative safety and postoperative regimens for graft patency and preventing ischemic events.

Purpose of the Study:

  • To systematically review risks and benefits of preoperative aspirin and clopidogrel.
  • To determine optimal aspirin timing and dosage post-CABG.
  • To assess the role of postoperative clopidogrel therapy.

Main Methods:

  • Systematic review of Medline database.
  • Literature search from 1978 to 2008.
  • Analysis of antiplatelet therapy strategies in CABG patients.

Main Results:

  • Aspirin cessation for 7-10 days pre-CABG is suggested, but debated.
  • Clopidogrel should be stopped at least 5 days before CABG to minimize bleeding.
  • Postoperative aspirin (100-325 mg daily, started within 48h) is strongly supported; clopidogrel use is less defined but recommended for acute coronary syndrome patients.

Conclusions:

  • Despite extensive use, perioperative antiplatelet management for CABG needs refinement.
  • Ongoing trials will clarify optimal aspirin and clopidogrel use.
  • Evidence supports aspirin post-CABG, while clopidogrel's role is evolving.

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...
