Insights

Short dual-antiplatelet therapy (DAPT) of 1 or 3 months was found to be noninferior for ischemic outcomes in high bleeding risk patients undergoing PCI. This abbreviated DAPT approach may also reduce major bleeding events.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Pharmacology

Background:

  • Optimal dual-antiplatelet therapy (DAPT) duration for high bleeding risk (HBR) patients undergoing percutaneous coronary intervention (PCI) with current drug-eluting stents is not well-defined.
  • Drug-eluting stents are preferred for HBR patients, necessitating research into safe and effective DAPT strategies.

Purpose of the Study:

  • To evaluate two abbreviated DAPT regimens in HBR patients who have undergone PCI.
  • To compare the safety and efficacy of 1-month and 3-month DAPT versus longer durations.

Main Methods:

  • The XIENCE Short DAPT program comprised three prospective, single-arm studies in HBR patients receiving cobalt-chromium everolimus-eluting stents.
  • Patients received 1-month (XIENCE 28) or 3-month (XIENCE 90) DAPT, discontinuing P2Y12 inhibitors thereafter.
  • Propensity score-stratified analysis was used with historical controls (XIENCE V USA).

Main Results:

  • A total of 3,652 patients were enrolled.
  • 1-month and 3-month DAPT were noninferior to 6-month and 12-month DAPT for ischemic outcomes (all-cause mortality or myocardial infarction).
  • While not significantly reducing BARC types 2-5 bleeding, both abbreviated DAPT durations reduced BARC types 3-5 bleeding; stent thrombosis rates were low (0.2%-0.3%).

Conclusions:

  • Abbreviated DAPT durations of 1 or 3 months are noninferior to longer durations for ischemic outcomes in HBR patients treated with cobalt-chromium everolimus-eluting stents.
  • These shorter DAPT regimens may be associated with reduced major bleeding and maintain a low incidence of stent thrombosis.

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...

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
