| Summary: | Ischemic cardiomyopathy remains a leading cause of heart failure, yet the optimal revascularization approach for patients with reduced left ventricular function remains uncertain. This review synthesizes current evidence on coronary revascularization strategies, emphasizing real-world applicability and individualized treatment. It critically evaluates the benefits and limitations of coronary artery bypass grafting [CABG] and percutaneous coronary intervention [PCI], highlighting key knowledge gaps. Findings from the STICH trial demonstrate that CABG improves long-term survival despite an elevated early procedural risk, particularly in patients with extensive multivessel disease. In contrast, the REVIVED-BCIS2 trial suggests that PCI enhances quality of life but does not significantly reduce mortality compared to optimal medical therapy, making it a viable alternative for high-risk patients ineligible for surgery. This review underscores the role of advanced imaging techniques in myocardial viability assessment and emphasizes the importance of comprehensive risk stratification in guiding revascularization decisions. Special attention is given to managing high-risk patients unsuitable for CABG and the potential benefits of PCI in symptom relief despite uncertain survival benefits. A stepwise algorithm is proposed to assist clinicians in tailoring revascularization strategies, reinforcing the need for a multidisciplinary Heart Team approach to optimize outcomes. |
