Precision Subtyping and Prognostic Study of Heart Failure Based on Multi-Omics Integration and Clinical Indicators: A Prospective Single-Center Cohort Study
Chronic Heart FailureHeart Failure With Reduced Ejection Fraction (HFrEF)Heart Failure With Preserved Ejection Fraction (HFPEF)Heart Failure With Mildly Reduced Ejection Fraction (HFmrEF)
Study 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.

Inclusion Criteria:(1)For chronic heart failure (CHF) patients:1.Meet the 2022 European Society of Cardiology (ESC) diagnostic criteria for CHF, classified into heart failure with reduced ejection fraction (HFrEF), heart failure with mildly reduced ejection fraction (HFmrEF), and heart failure with preserved ejection fraction (HFpEF) per ESC guidelines;2.Aged 18 to 80 years (inclusive);3.Able to provide written informed consent independently (or via a legal guardian if cognitively impaired, with a Mini-Mental State Examination \[MMSE\] score ≥ 24).
(2)For healthy controls:1.No history of cardiovascular disease, confirmed by medical history review and baseline echocardiography;2.Aged 18 to 80 years (inclusive), matched 1:2 with CHF patients by age and gender;3.Able to provide written informed consent.
Exclusion Criteria:(1)Acute decompensated heart failure (admitted for acute HF exacerbation within 72 hours prior to enrollment);(2)End-stage renal disease, defined as an estimated glomerular filtration rate (eGFR) \< 15 mL/min/1.73m² (confirmed by serum creatinine testing);(3)Active malignancies (receiving systemic treatment within 6 months prior to enrollment) or severe systemic diseases (e.g., severe liver failure, active autoimmune diseases);(4)Antibiotic use within 2 weeks prior to enrollment (may interfere with gut microbiome analysis);(5)Inability to complete 12-month follow-up (e.g., planned long-term overseas residence) or provide required biological samples (e.g., venous blood, fecal samples).
Primary outcome measure(s)
1-Year Composite Endpoint by HF Subtype (Heart Failure Rehospitalization or All-Cause Death) — 12 months Occurrence of heart failure-related rehospitalization or all-cause death within 12 months after enrollment, stratified by heart failure subtypes (HFrEF, HFmrEF, HFpEF).Subtype stratification is based on the 2022 ESC HF classification criteria; endpoints are confirmed by the study's clinical endpoint adjudication committee.
