It represents the advanced stage of many cardiovascular diseases and remains a major global health challenge. Despite progress in medical and interventional therapies, patients with chronic heart failure continue to experience high rates of death, hospitalization, and long-term disability.\n\nIschemic heart failure, which develops as a result of coronary artery disease and prior myocardial infarction, is the most common form of chronic heart failure. Current treatment strategies, including guideline-directed medical therapy and revascularization procedures, can improve symptoms and outcomes but do not fully address the residual risk of adverse cardiovascular events. Therefore, additional therapeutic approaches are needed to further improve long-term prognosis in this population.\n\nAbnormal myocardial energy metabolism is a key pathological feature of heart failure. Mitochondria play a central role in energy production, and impaired mitochondrial function contributes to disease progression. Previous studies by our group have identified mitochondrial aldehyde dehydrogenase 2 (ALDH2) as an important regulator of myocardial metabolic homeostasis and cardiac protection under ischemic and stress conditions.\n\nAlpha-lipoic acid is a vitamin B-related compound with antioxidant properties and has been widely used in clinical practice for other indications. Increasing evidence suggests that alpha-lipoic acid may also exert protective effects in cardiovascular diseases, potentially through modulation of mitochondrial function. Experimental studies have shown that alpha-lipoic acid can restore ALDH2 activity and improve cardiac function in models of heart failure.\n\nBased on these findings, we conducted an exploratory randomized controlled trial between 2019 and 2023 to evaluate the safety and potential efficacy of alpha-lipoic acid in patients with ischemic heart failure. In this multicenter study, patients receiving alpha-lipoic acid showed favorable trends toward reduced risk of death and heart failure-related hospitalization, as well as significant improvements in left ventricular ejection fraction and exercise capacity, without an increase in adverse events.\n\nTaken together, prior mechanistic research and early clinical evidence support the hypothesis that alpha-lipoic acid may provide additional benefit when used as adjunctive therapy in patients with chronic ischemic heart failure. The present study is designed to further evaluate whether long-term supplementation with alpha-lipoic acid can reduce major adverse cardiovascular events and improve clinical outcomes in this population.",[341],"Heart Failure Due to Coronary Artery Disease",[343,344,345],"alpha lipoic acid","major adverse cardiovascular events","Ischemic heart failure","NOT_YET_RECRUITING","2026-08-04",{"date":349,"type":350},"2026-08-05","ACTUAL",{"date":352,"type":335},"2026-11-01",{"date":354,"type":335},"2030-12-01",{"name":5,"class":6},21]
