研究目的:

本研究旨在探究心肌组织中R loop水平与心力衰竭的临床表型之间的关联,为心力衰竭(特别是HFpEF)提供R loop相关分子通路的新颖的治疗靶点。  

Objectives of Study:

This study aims to explore the association between R loop levels in cardiac tissue and the clinical phenotype of heart failure, providing novel therapeutic targets for heart failure (especially HFpEF) related to R loop molecular pathways.

Inclusion criteria

Inclusion Criteria for HFpEF Group: 1. previous or current clinical symptoms or signs of heart failure; 2. an echocardiogram within 12 months prior to myocardial biopsy or cardiac surgery showing LVEF >= 50%; 3. objective evidence of left ventricular diastolic dysfunction or elevated filling pressure, meeting at least two of the following: echocardiographic structural abnormalities (left ventricular hypertrophy or left atrial enlargement) or diastolic dysfunction (E/e’ > 9), elevated serum natriuretic peptides (BNP >= 35 pg/mL or NT-proBNP >= 125 pg/mL in sinus rhythm; BNP >= 105 pg/mL or NT-proBNP >= 365 pg/mL in atrial fibrillation), or hemodynamic evidence of elevated left ventricular filling pressure (resting PAWP >= 15 mmHg or post-exercise PAWP >= 25 mmHg); 4. at least one of the following: age > 60 years, hypertension, coronary artery disease, atrial fibrillation, pulmonary hypertension (PASP > 35 mmHg), obesity (BMI > 28 kg/m2), diabetes, chronic kidney disease, or chronic obstructive pulmonary disease. Inclusion Criteria for HFrEF Group: 1. previous or current clinical symptoms or signs of heart failure; 2. an echocardiogram within 12 months prior to myocardial biopsy or cardiac surgery demonstrating a documented LVEF < 40%; 3. at least one of the following: age > 60 years, hypertension, coronary artery disease, atrial fibrillation, pulmonary hypertension (PASP > 35 mmHg), obesity (BMI > 28 kg/m2), diabetes, chronic kidney disease, or chronic obstructive pulmonary disease. Inclusion Criteria for the National Brain Bank Control Group: Control samples were provided by the National Human Brain Bank for Development and Function (Chinese Academy of Medical Sciences & Peking Union Medical College). 1. under 70 years of age (due to the high prevalence of comorbid diastolic dysfunction and HFpEF in advanced age), 2. whose cause of death was non-cardiac (specifically excluding sudden cardiac death, myocardial infarction, heart failure, or cardiac arrest; priority was given to cases of accidental death).

HFpEF组排除标准: 1.有LVEF <40%的临床病史。 2.经临床评估或心肌活检病理确诊如下特殊类型病因所致心衰:浸润性心肌病(心肌淀粉样变、糖原贮积病、含铁血黄素沉着症等)、心肌炎(如感染性心肌炎、自身免疫性心肌炎、炎性肌病、嗜酸粒细胞性心肌炎、免疫治疗相关心肌炎等)、限制性心包炎、其他特殊类型心肌病(肥厚型梗阻性心肌病、致心律失常性右心室发育不良/右心室心肌病、遗传性心肌病)等。 3.心脏移植史。 HFrEF组排除标准: 1.经临床评估明确心力衰竭由全身系统性疾病引起:严重的全身感染、自身免疫疾病高度活动、未控制的甲状腺功能亢进、严重贫血等。 2.经临床评估或心肌活检病理确诊如下特殊类型病因所致心衰:浸润性心肌病(心肌淀粉样变、糖原贮积病、含铁血黄素沉着症等)、心肌炎(如感染性心肌炎、自身免疫性心肌炎、炎性肌病、嗜酸粒细胞性心肌炎、免疫治疗相关心肌炎等)、限制性心包炎、其他特殊类型心肌病(肥厚型梗阻性心肌病、致心律失常性右心室发育不良/右心室心肌病、遗传性心肌病)等。 3.心脏移植史。 对照组排除标准: 1.排除生前简要临床病史中合并心力衰竭、心肌病变诊断的患者。 2.排除严重全身系统性高炎症状态疾病(如感染性休克、脓毒症、自身免疫性疾病活动)、血管性疾病(动脉粥样硬化性脑梗死),或经临床评估不适宜作为对照组的患者。

Exclusion criteria:

Exclusion Criteria for HFpEF Group: 1. a clinical history of LVEF < 40%; 2. heart failure caused by specific etiologies as confirmed by clinical evaluation or myocardial biopsy pathology, including infiltrative cardiomyopathies (such as cardiac amyloidosis, glycogen storage disease, or hemosiderosis), myocarditis (e.g., infectious, autoimmune, inflammatory myopathy, eosinophilic myocarditis, or immune therapy-related myocarditis), constrictive pericarditis, or other specific cardiomyopathies (such as hypertrophic obstructive cardiomyopathy, arrhythmogenic right ventricular dysplasia/cardiomyopathy, or hereditary cardiomyopathies); 3. a history of heart transplantation. Exclusion Criteria for HFrEF Group: 1. heart failure determined by clinical evaluation to be caused by systemic conditions, including severe systemic infection, highly active autoimmune disease, uncontrolled hyperthyroidism, or severe anemia; 2. heart failure due to specific etiologies confirmed clinically or by myocardial biopsy, such as infiltrative cardiomyopathies (e.g., cardiac amyloidosis, glycogen storage disease, hemosiderosis), myocarditis (including infectious, autoimmune, inflammatory myopathy, eosinophilic, or immune therapy-related myocarditis), constrictive pericarditis, or other specific cardiomyopathies (such as hypertrophic obstructive cardiomyopathy, arrhythmogenic right ventricular dysplasia/cardiomyopathy, or hereditary cardiomyopathies). 3. a history of heart transplantation. Exclusion Criteria for control group: 1. a documented clinical history of heart failure or cardiomyopathy prior to death, 2. severe systemic inflammatory conditions (such as septic shock, sepsis, or active autoimmune diseases), cerebrovascular disease (e.g., atherosclerotic cerebral infarction), or any other condition deemed clinically inappropriate for inclusion as controls upon medical evaluation.
