Revascularization in coronary artery disease. A review of randomized trial data.

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.
