Insights
Dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) now balances ischemic and bleeding risks. New strategies aim to reduce bleeding in high-risk patients without worsening ischemic events.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Dual antiplatelet therapy (DAPT) post percutaneous coronary intervention (PCI) historically prioritized preventing ischemic events over bleeding.
- Emerging evidence indicates major bleeding complications carry risks comparable to ischemic events.
- Patients at high bleeding risk (HBR) are often underrepresented in DAPT trials and face elevated ischemic event risk.
Purpose of the Study:
- To review pharmacotherapeutic strategies for reducing bleeding risk in HBR patients undergoing PCI.
- To evaluate methods that minimize bleeding without compromising ischemic protection.
Main Methods:
- Review of current evidence on novel pharmacotherapeutic strategies.
- Analysis of approaches including shortened DAPT duration, early aspirin withdrawal, and P2Y12 inhibitor de-escalation.
Main Results:
- Discusses strategies to mitigate bleeding risk in HBR patients post-PCI.
- Highlights the importance of balancing antithrombotic and antihemorrhagic effects.
Conclusions:
- New strategies are crucial for optimizing outcomes in HBR patients undergoing PCI.
- Reducing bleeding risk is essential for improving overall prognosis in this population.
Abstract:
Historically, prevention from ischemic events with dual antiplatelet therapy (DAPT) post percutaneous coronary intervention (PCI) took precedence over protection from bleeding. However, increasing data suggest that major bleeding complications are as detrimental as ischemic events. Awareness about the prognostic impact of bleeding prompted the search for new strategies aimed at maximizing both ischemic and bleeding protection. This is noteworthy because patients at high bleeding risk (HBR) have generally been underrepresented in clinical trials on DAPT and they often are at increased risk of ischemic events as well. The present review discusses the evidence base for new pharmacotherapeutic strategies to decrease bleeding risk without compromising ischemic protection among HBR patients undergoing PCI, including shortening DAPT duration, early aspirin withdrawal, and inhibitor de-escalation.
