Antithrombotic Therapy in Acute Coronary Syndrome Patients with End-Stage Renal Disease: Navigating Efficacy and Safety

Cardiovascular disease is the primary cause of mortality and morbidity in patients with chronic kidney disease (CKD), particularly those with end stage renal disease (ESRD) undergoing hemodialysis. This paper examines the challenges of managing acute coronary syndrome (ACS) in ESRD patients, focusing on the delicate balance between thrombotic and bleeding risks. The review explores the mechanisms underlying the increased thrombotic risk in ESRD, including elevated platelet aggregation, endothelial dysfunction, and alterations in coagulation factors. Paradoxically, ESRD patients also exhibit higher bleeding tendencies due to platelet dysfunction and other uremia-related factors. The efficacy and safety of various antiplatelet therapies, including aspirin and P2Y12 inhibitors, are evaluated in this population. While potent P2Y12 inhibitors such as ticagrelor and prasugrel have demonstrated potential in reducing ischemic events, they are associated with an increased bleeding risk. The optimal duration of anti-platelet therapy (DAPT)in ESRD patients remains controversial, with studies suggesting potential benefits of prolonged DAPT but also increased bleeding risk. This review underscores the necessity for further research and patient inclusion in clinical trials to establish evidence-based guidelines for tailoring antithrombotic therapy in this high-risk population.
