Summary

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.

Detailed description

This prospective single-center cohort study focuses on chronic heart failure (CHF) patients (HFrEF, HFmrEF, HFpEF) and healthy controls, with the core objective of establishing a precision risk stratification model for CHF via multi-omics-clinical integration. Study Design \& Enrollment Participants: 400 CHF patients (meeting 2022 ESC HF guidelines) and 200 age/gender-matched healthy controls (no cardiovascular disease history). Exclusion criteria include acute decompensated HF, end-stage renal disease, active malignancies, and recent antibiotic use (to avoid gut microbiome interference). Recruitment: Conducted at The First Affiliated Hospital of Xinjiang Medical University over 12 months; eligible participants will provide written informed consent prior to enrollment. Data \& Sample Collection Baseline: Clinical data: NYHA functional class, NT-proBNP, echocardiography (LVEF, LVGLS), cardiac CT (EAT density/volume); Multi-omics samples: Plasma (proteome via Olink, metabolome via LC-MS), blood (genome via microarray), feces (gut microbiome via 16S rRNA sequencing; shotgun metagenomics for 200 patients); Follow-up: 3/6/12-month visits to collect clinical outcomes (rehospitalization, mortality), KCCQ quality-of-life scores, and dynamic multi-omics samples (only for SGLT2 inhibitor-treated patients). Key Analyses Multi-omics characterization: Identify phenotype-specific molecular signatures (e.g., HFpEF-related metabolic profiles) via differential expression and correlation network analysis; Mechanistic exploration: Link gut microbiome composition to circulating metabolites/inflammatory proteins to clarify the "gut-heart axis" in CHF; Model construction: Integrate multi-omics and clinical/imaging indicators to build 4 prediction models (clinical-only, single-omics, multi-omics, integrated), with validation via Harrell's C-statistic and time-dependent ROC. Quality Control Biological samples: Labeled with unique IDs, stored at -80°C; Imaging data: Independent review by 2 cardiologists (third-party arbitration for discrepancies); Data management: REDCap platform for electronic data capture; independent Data Monitoring Committee (DMC) reviews progress/safety every 6 months.
