简要总结
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.
详细描述
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.

入选标准
- •(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.
排除标准
- •(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).
