This single-center prospective observational study aims to evaluate differences in metabolomic pathways between patients with ischemic and non-ischemic cardiomyopathy with reduced left ventricular ejection fraction and documented ventricular tachycardia. Patients followed at Istanbul University-Cerrahpasa Cardiology Institute Hospital will be included if they meet predefined eligibility criteria. Participants will be categorized into two cohorts according to the etiology of cardiomyopathy: ischemic and non-ischemic. Biospecimens will be collected for metabolomic analyses to identify alterations in metabolic pathways and individual metabolites. The study also aims to explore associations between metabolomic profiles and clinical characteristics, including arrhythmia burden and cardiac function parameters. The findings may provide insights into the underlying pathophysiological mechanisms of ventricular arrhythmias in heart failure and contribute to improved risk stratification and personalized management strategies.
