研究目的: |
本研究旨在利用真实世界电子病历数据,首先识别接受指南指导药物治疗(GDMT)的射血分数降低的心力衰竭(HFrEF)患者中左心室逆向重构(LVRR)的典型纵向轨迹,进而量化分析影响其重构速率的关键临床特征与治疗因素。 |
||||||||||||||||||||||
|
Objectives of Study: |
This study aims to use real-world electronic medical record data to first identify the typical longitudinal trajectories of left ventricular reverse remodeling (LVRR) in patients with heart failure with reduced ejection fraction (HFrEF) who are receiving guideline-directed medical therapy (GDMT), and then quantitatively analyze the key clinical characteristics and therapeutic factors that affect the rate of such remodeling. |

纳入标准: |
1.年龄 ≥ 18周岁; 2.经临床明确诊断为心力衰竭(诊断符合《2022 AHA/ACC/HFSA心力衰竭管理指南》标准); 3.本次住院期间首次启动,或经评估为首次优化指南指导的药物治疗,并至少包含以下四联药物中的两类:β受体阻滞剂、肾素-血管紧张素系统抑制剂、盐皮质激素受体拮抗剂、SGLT2抑制剂; 4.基线经超声心动图检查(GDMT启动/优化前或同期完成)经规范测量(优先采用Simpson双平面法),确认左心室射血分数 < 40%; 5.具备可用于左心室逆向重构轨迹分析的纵向核心数据:GDMT治疗稳定后(定义为启动/优化GDMT并出院后≥30天),拥有至少两次规范性超声心动图随访检查记录,且两次检查均在随访起点(治疗稳定后3个月)后,检查间隔 ≥1个月; |
||||||||||||||||||||||
|
Inclusion criteria |
1.Age >= 18 years; 2.Clinical diagnosis of heart failure meeting the criteria of the *2022 AHA/ACC/HFSA Heart Failure Management Guideline; 3.Initiation or first optimization of Guideline-Directed Medical Therapy during the index hospitalization, including at least two drug classes among: beta-blockers, renin-angiotensin system inhibitors, mineralocorticoid receptor antagonists, and SGLT2 inhibitors; 4.Baseline echocardiography (performed prior to or concurrently with GDMT initiation/optimization) with standardized measurement (preferably Simpson‘s biplane method) confirming a left ventricular ejection fraction (LVEF) < 40%; 5.Availability of longitudinal core data for LVRR trajectory analysis: at least two standardized echocardiographic follow-up records after achieving stable GDMT (defined as >=30 days after initiation/optimization and discharge), with both examinations occurring after the efficacy observation start point (3 months post-stabilization) and an inter-examination interval of >=1 month; |
||||||||||||||||||||||
|
排除标准: |
1.基线或随访期超声心动图数据缺失或质量不佳,无法准确测量LVEF及左心室内径; 2.存在严重干扰心脏结构与功能评估的疾病(包括但不限于:重度瓣膜病未干预、入组前3个月内发生急性心肌梗死、缩窄性心包炎、既往有心脏移植或左心室辅助装置植入史); 3.临床随访资料严重缺失,无法判断GDMT治疗依从性; 4.终末期肾病长期依赖肾脏替代治疗; 5.妊娠期或哺乳期女性; |
||||||||||||||||||||||
|
Exclusion criteria: |
1.Missing or poor-quality echocardiographic data at baseline or during follow-up precluding accurate measurement of LVEF and left ventricular dimensions; 2.Conditions severely interfering with cardiac structure and function assessment (including but not limited to: severe valvular disease without intervention, acute myocardial infarction within 3 months prior to enrollment, constrictive pericarditis, history of heart transplantation or left ventricular assist device implantation); 3.Severely missing clinical follow-up data, preventing assessment of GDMT adherence; 4.End-stage renal disease with long-term dependence on renal replacement therapy; 5.Pregnancy or lactation |
