A cost analysis of coronary stenting without anticoagulation versus stenting with anticoagulation using warfarin
1Division of Cardiovascular Diseases, University of Alabama of Birmingham 35294, USA.
Insights
Antiplatelet therapy after coronary artery stenting is more cost-effective than warfarin anticoagulation. Patients on antiplatelet therapy alone experienced shorter hospital stays and lower hospitalization costs.
Area of Science:
- Cardiology
- Pharmacology
- Health Economics
Background:
- Coronary artery stenting necessitates antithrombotic therapy to prevent stent thrombosis.
- Current guidelines offer various antithrombotic strategies, including antiplatelet therapy and anticoagulation.
Purpose of the Study:
- To compare hospitalization costs and length of stay between antiplatelet therapy and warfarin anticoagulation post-coronary artery stenting.
Main Methods:
- A case-controlled study design was employed.
- Two groups of patients were compared: one managed with antiplatelet therapy only, and another treated with warfarin anticoagulation.
- Hospitalization costs and length of hospital stay were the primary outcome measures.
Main Results:
- Patients receiving antiplatelet therapy alone demonstrated significantly lower total hospitalization costs.
- The average hospital stay was significantly reduced in the antiplatelet therapy group compared to the anticoagulation group.
Conclusions:
- Antiplatelet therapy alone appears to be a more cost-effective strategy post-coronary artery stenting.
- This approach is associated with reduced healthcare resource utilization, specifically shorter hospital stays and lower costs.
Abstract:
A case-controlled study was performed comparing hospitalization costs and length of hospital stay in a group of patients managed with antiplatelet therapy only, versus a group treated with anticoagulation using warfarin after coronary artery stenting. The patients managed with antiplatelet therapy alone had significantly reduced total hospitalization costs and a significantly reduced average hospital stay than patients managed with anticoagulation.
