Insights
Ischemic left ventricular dysfunction (iLVD) management is evolving. This review clarifies coronary revascularization benefits for heart failure patients and guides percutaneous coronary intervention (PCI) decisions.
Area of Science:
- Cardiology
- Heart Failure Research
- Interventional Cardiology
Background:
- Ischemic left ventricular dysfunction (iLVD) is a leading cause of heart failure with reduced ejection fraction.
- iLVD is linked to higher mortality rates compared to nonischemic cardiomyopathy.
- Historically, coronary revascularization was standard for iLVD, but recent trials challenge this practice.
Purpose of the Study:
- To review the pathophysiology of iLVD.
- To analyze randomized trial evidence regarding coronary revascularization in iLVD.
- To define patient selection criteria for coronary artery bypass grafting and percutaneous coronary intervention (PCI) in iLVD.
Main Methods:
- Comprehensive literature review of pathophysiology and clinical trials.
- Analysis of randomized evidence for coronary revascularization strategies.
- Development of a practical guide for PCI in iLVD patients.
Main Results:
- The review synthesizes current understanding of iLVD pathophysiology.
- Evidence from recent randomized trials is critically examined.
- Guidelines are provided for selecting iLVD patients who benefit from revascularization.
Conclusions:
- Coronary revascularization decisions for iLVD require careful patient selection.
- Percutaneous coronary intervention (PCI) planning and execution are detailed.
- Shared decision-making and complete revascularization are emphasized, with future mechanical circulatory support trials noted.
Abstract:
Ischemic left ventricular dysfunction (iLVD) is the most prevalent cause of heart failure with reduced ejection fraction and is associated with higher mortality than nonischemic cardiomyopathy. Coronary revascularization was once considered routine for patients with iLVD, yet recent randomized trials have questioned this approach. This state-of-the-art review examines the pathophysiology of iLVD, explores the randomized evidence around coronary revascularization, and outlines which patients with iLVD should still be offered coronary artery bypass grafting or percutaneous coronary intervention (PCI). Finally, a step-by-step guide for planning and performing PCI in this population is provided. Attention is given to shared decision-making, nontechnical factors, and considerations for achieving complete revascularization, with a specific focus on upcoming trials of mechanical circulatory support.
