Revascularization in coronary artery disease. A review of randomized trial data
1University of California School of Medicine, San Francisco, USA.
Insights
Coronary artery disease revascularization strategies vary globally, often influenced by economics over evidence. This review analyzes randomized trials and meta-analyses to guide evidence-based clinical decisions for patient subgroups.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Health Services Research
Background:
- Coronary artery disease (CAD) treatment has evolved significantly since the introduction of bypass surgery and catheter-based interventions.
- Current practice patterns for CAD revascularization show global and domestic inconsistencies, often prioritizing economic factors and availability over evidence-based data.
- Technological advancements in CAD treatment modalities, including medical therapy, angioplasty, atherectomy, stenting, and bypass surgery, outpace the available comparative study data.
Purpose of the Study:
- To review and synthesize data from randomized trials and meta-analyses comparing different revascularization modalities for coronary artery disease.
- To provide a framework for evidence-based clinical decision-making in CAD management.
- To offer a revascularization strategy for specific patient subgroups based on current clinical evidence.
Main Methods:
- Systematic review of randomized trials and meta-analyses comparing revascularization strategies for coronary artery disease.
- Analysis of comparative data for medical therapy, balloon angioplasty, atherectomy, coronary stenting, and bypass surgery.
- Framework development for clinical decision-making based on synthesized evidence.
Main Results:
- Inconsistent global and US practice patterns in coronary artery disease revascularization, often driven by non-clinical factors.
- Significant lag in comparative studies for revascularization modalities relative to technological advancements.
- Identification of specific patient subgroups for whom evidence supports particular revascularization strategies.
Conclusions:
- Clinical decision-making for coronary artery disease revascularization requires a framework grounded in evidence from randomized trials and meta-analyses.
- Addressing practice pattern inconsistencies and aligning treatment with evidence are crucial for optimal patient care.
- The optimal revascularization strategy for coronary artery disease is evolving and should be tailored to patient subgroups based on robust clinical data.
Abstract:
Since the advent of bypass surgery in the late 1960s and catheter-based intervention in the late 1970s, the treatment of coronary artery disease has been revolutionized by the concept of revascularization. Surveys have demonstrated that the practice patterns around the world and within the US are inconsistent for these important treatment options and are often driven by availability and economics rather than evidence-based data. In addition, the studies examining the use of medical therapy, balloon angioplasty, atherectomy, coronary stenting, and bypass surgery are consistently lagging behind the technological advances in this field. This article reviews the data that randomized trials and meta-analyses provide to compare these modalities. We attempt to provide a framework for reasoned clinical decision making to help guide patient care. While the breakpoints between the medicine bottle, cath lab, and operating room will continue to evolve, we offer a revascularization strategy for patient subgroups based on what clinical data supports.
