Optimal revascularization strategies for multivessel coronary artery disease

The aim of this article is to review the current status of optimal revascularization strategies in patients presenting with multivessel coronary artery disease.

Coronary artery bypass surgery is the gold standard for patients with multivessel disease. Recent developments in the interventional field, like drug-eluting stents, which significantly reduced restenosis and the need for repeat revascularizations, have cut back one of the largest limitations of percutaneous coronary intervention.

There is currently little evidence to believe that in a general population, opting for either coronary artery bypass surgery or percutaneous coronary intervention would imply a better long-term survival. Coronary artery bypass surgery is still associated with higher rates of complete revascularization and a higher durability than percutaneous coronary intervention, resulting in lower rates of repeat revascularization. The current evidence, however, is based on sub-optimal inconclusive data from single center or multicenter registries. Until the results of several dedicated ongoing randomized trials are presented, the choice for a revascularization strategy should be made not only on the basis of feasibility but also by taking into account each patient's co-morbidities and risk factors. Careful monitoring of glycemic control and lipid concentrations and an optimal pharmacological treatment are at least as important in achieving an optimal outcome.
