Insights
Revascularization may improve outcomes for heart failure patients with ischemic cardiomyopathy. Choosing between coronary artery bypass grafting and percutaneous coronary intervention depends on individual patient factors and ejection fraction.
Area of Science:
- Cardiology
- Cardiac Surgery
- Interventional Cardiology
Background:
- Coronary artery disease is a leading cause of heart failure.
- The role of revascularization in ischemic cardiomyopathy lacks consensus.
- Myocardial viability is key to revascularization benefits.
Purpose of the Study:
- To review the role of revascularization in ischemic cardiomyopathy.
- To discuss the selection of patients for revascularization.
- To compare coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI).
Main Methods:
- Review of observational studies and registry data.
- Discussion of pathophysiologic principles of myocardial recovery.
- Consideration of clinical decision-making in heart failure management.
Main Results:
- Observational data suggest improved outcomes with revascularization (CABG or PCI) versus medical therapy.
- Viability testing may identify patients who benefit most.
- Registry data favor CABG over PCI in reduced ejection fraction patients.
- PCI is a reasonable option for focal disease, comorbidities, or prior surgery if complete revascularization is achievable.
Conclusions:
- Revascularization is a potential strategy for heart failure with ischemic cardiomyopathy.
- Patient selection using viability testing is important.
- CABG and PCI are complementary approaches, with choices guided by patient-specific factors.
Abstract:
Coronary artery disease is the most common underlying cause of heart failure, yet there is little consensus on the role of revascularization in the management of patients with ischemic cardiomyopathy. The concept of recovery of dysfunctional but viable myocardium forms the pathophysiologic basis for the benefit of revascularization. Data from observational studies suggest that patients with coronary disease and left ventricular dysfunction may have improved outcomes after surgical revascularization or percutaneous coronary intervention (PCI) compared to medical treatment. Viability testing may be useful in selecting a population of patients who will receive differential benefit. In the clinical management of patients with heart failure, clinicians face challenging decisions about whether to recommend revascularization especially in patients who do not have angina. As data from randomized trials are awaited, PCI and coronary artery bypass grafting may be considered as complimentary revascularization approaches. Registry data suggest a benefit of coronary artery bypass grafting over PCI in patients with reduced ejection fraction; however, in patients with focal disease and comorbidities including previous surgery, PCI is reasonable, especially if complete revascularization is possible.
