Abstract
Ischemic cardiomyopathy (ICM) is the most prevalent cause of heart failure (HF) in developed countries, with significant morbidity and mortality, despite constant improvements in the management of coronary artery disease. Current literature on this topic remains fragmented. Therefore, this review aimed to summarize the most recent data on ICM, focusing on its definition, epidemiology, outcomes, and therapeutic options. The most widely accepted definition is represented by a left ventricular dysfunction in the presence of significant coronary artery disease. The prevalence of ICM is largely influenced by age and sex, with older individuals and males being more affected. Its pathophysiology is characterized by plaque buildup, thrombus formation, hypoperfusion, ischemic cell death, and left ventricular remodeling. Despite improvements in therapy, ICM still represents a public health burden, with a 1-year mortality rate of 16% and a 5-year mortality rate of approximately 40% in the USA and Europe. Therefore, optimization of cardiovascular function, prevention of progressive remodeling, reduction of HF symptoms, and improved survival are the main goals of treatment. Therapeutic options for ICM include lifestyle changes, optimal medical therapy, revascularization, device therapy, mechanical circulatory support, and cardiac transplantation. Personalized management strategies and tailored patient care are needed to improve the outcomes of patients with ICM.

Treatment Strategies for Chronic Coronary Heart Disease with Left Ventricular Systolic Dysfunction or Preserved Ejection Fraction-A Systematic Review and Meta-Analysis. PATHOPHYSIOLOGY 2023; 30:640-658. [PMID: 38133147 PMCID: PMC10747738 DOI: 10.3390/pathophysiology30040046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 12/11/2023] [Accepted: 12/13/2023] [Indexed: 12/23/2023] Open
Abstract
In this meta-analysis, we examine the advantages of invasive strategies for patients diagnosed with chronic coronary heart disease (CHD) and preserved left ventricular (LV) function, as well as those with significant LV systolic dysfunction (LV ejection fraction (EF) < 45%). MATERIAL AND METHODS We conducted a systematic search to identify all randomized trials directly comparing invasive strategies with optimal medical therapy (OMT) in patients diagnosed with chronic CHD. Data from these trials were pooled using a random-effects meta-analysis. The primary outcome assessed was the all-cause mortality, while secondary endpoints included cardiovascular (CV) death, stroke, myocardial infarction (MI), and unplanned revascularization. This study was designed to assess the benefits of both invasive strategies and OMT in patients with preserved LV function and in those with LV systolic dysfunction. The statistical analysis of the data was conducted using the Review Manager (RevMan) software, version 5.4.1 (The Cochrane Collaboration, 2020). RESULTS Twelve randomized studies enrolling 13,912 patients were included in the final analysis. Among the patients with chronic CHD and preserved LV systolic function, revascularization did not demonstrate a reduction in all-cause mortality (8.52% vs. 8.45%, p = 0.45), CV death (3.41% vs. 3.62%, p = 0.08), or the incidence of MI (9.88% vs. 10.49%, p = 0.47). However, the need for unplanned myocardial revascularization was significantly lower in the group following the initial invasive approach compared to patients undergoing OMT (14.75% vs. 25.72%, p < 0.001). In contrast, the invasive strategy emerged as the preferred treatment modality for patients with ischemic LV systolic dysfunction. This approach demonstrated lower rates of all-cause mortality (40.61% vs. 46.52%, p = 0.004), CV death (28.75% vs. 35.82%, p = 0.0004), and MI (8.19% vs. 10.8%, p = 0.03). CONCLUSIONS In individuals diagnosed with chronic CHD and preserved LV EF, the initial invasive approach did not demonstrate a clinical advantage over OMT. Conversely, in patients with ischemic LV systolic dysfunction, myocardial revascularization was found to reduce the risks of CV events and enhance the overall outcomes. These findings hold significant clinical relevance for optimizing treatment strategies in patients with chronic CHD, contingent upon myocardial contractility status.

Abstract
Coronary artery disease (CAD) is the most common cause of heart failure with reduced ejection fraction (HFrEF). Advances and innovations in medical therapy have been shown to play a crucial role in improving the prognosis of patients with CAD and HFrEF; however, mortality rate in these patients remains high, and the role of surgical and/or percutaneous revascularization strategy is still debated. The Surgical Treatment for Ischemic Heart Failure (STICH) trial and the Revascularization for Ischemic Ventricular Dysfunction (REVIVED) trial have attempted to provide an answer to this issue. Nevertheless, the results of these two trials have generated further uncertainties. Their findings do not provide a definitive answer about the ideal clinical phenotype for surgical or percutaneous coronary revascularization and dispute the historical dogma on myocardial viability and the theory of myocardial hibernation, raising new questions about the proper selection of patients who are candidates for coronary revascularization. The aim of this review is to provide an overview on the actual available evidence of coronary artery revascularization in patients with CAD and left ventricular dysfunction and to suggest new insights on the proper selection and management strategies in this high-risk clinical setting.
