Insights
Coronary stenting offers improved outcomes over balloon angioplasty, with initial higher costs often offset by reduced complications. Economic evaluations suggest stenting is cost-effective, especially for single-vessel disease.
Area of Science:
- Cardiovascular Medicine
- Health Economics
Background:
- Coronary stenting improves clinical outcomes and reduces restenosis compared to balloon angioplasty.
- Economic appraisals of coronary stenting are limited, with most conducted in the US.
- Early studies indicated higher medical costs for stenting due to longer hospital stays and complications.
Purpose of the Study:
- To review and summarize major economic evaluations comparing intracoronary stenting and balloon angioplasty.
- To assess the cost-effectiveness of coronary stenting procedures.
Main Methods:
- Review of existing economic appraisals and clinical trials.
- Analysis of cost data, including procedural costs, length of stay, and complication rates.
- Examination of long-term follow-up studies and modeling techniques.
Main Results:
- Initial costs associated with stenting were often higher but recovered through complication avoidance.
- Modeling studies suggest stenting is more cost-effective than balloon angioplasty, particularly in single-vessel disease.
- Advancements in stenting techniques may further justify procedural costs and healthcare resource consumption.
Conclusions:
- Coronary stenting is a clinically effective intervention with evolving cost-effectiveness.
- Long-term outcomes and newer techniques support the economic viability of stenting.
- Further large-scale studies are needed to confirm the economic benefits of advanced stenting techniques.
Abstract:
Elective coronary stenting has been shown to reduce restenosis and improve clinical outcomes compared with balloon angioplasty. Despite the availability of numerous large-scale randomised and controlled clinical trials, few economic appraisals have been performed and reported. The majority of these were conducted in the US. Nonetheless, early studies have suggested that medical care costs remain higher with stenting, in part due to the prolonged length of stay and frequent vascular complications related to early periprocedural anticoagulation regimens. Recent long-term follow-up studies have demonstrated that initial costs are often recovered by avoiding complications. Some studies mainly built on modelling techniques even suggest that stenting is more cost-effective than balloon angioplasty, chiefly in single-vessel disease. If advances in newer stenting techniques can be confirmed by large randomised controlled studies, the additional procedural costs and health care resource consumption might be even more justified. This paper reviews and summarises the major economic evaluations comparing intracoronary stenting and angioplasty.
