Precision Subtyping and Prognostic Study of Heart Failure Based on Multi-Omics Integration and Clinical Indicators: A Prospective Single-Center Cohort Study

This is a prospective single-center cohort study conducted at The First Affiliated Hospital of Xinjiang Medical University, aiming to enroll 400 patients with chronic heart failure (including HFrEF, HFmrEF, HFpEF) and 200 healthy controls.We will collect clinical data (e.g., NYHA class, NT-proBNP), multi-omics samples (genome, proteome, metabolome, gut microbiome), and imaging indicators (e.g., EAT density, myocardial strain) from participants at baseline. For patients treated with SGLT2 inhibitors, we will also track dynamic changes in multi-omics during follow-up.The main purpose is to build a composite risk prediction model (integrating multi-omics and clinical indicators) to predict the 1-year composite endpoint (heart failure rehospitalization or all-cause death). Secondary goals include identifying specific molecular profiles related to heart failure phenotypes, exploring the "gut-heart axis" mechanism, and finding early biomarkers for SGLT2 inhibitor response.All participants will be followed up for at least 12 months, and the study will strictly comply with ethical norms and protect the privacy of participants.
