研究目的:

慢性心力衰竭急性加重期(ADCHF)是心血管疾病终末阶段的主要临床表现,具有高发病率、再住院率和死亡率的特点。全球每年因ADCHF导致的住院人次超过100万,30天内再住院率高达25%,直接医疗支出占据心血管疾病总支出的2%-3%。当前临床标准治疗方案以利尿剂、血管扩张剂和正性肌力药物为主,但存在低血压、肾功能恶化等严重副作用,约15%-30%患者出现治疗抵抗。重组人脑利钠肽(新活素)作为血管扩张类正性肌力药物,通过双重机制改善血流动力学障碍,理论上具有更高的安全性阈值。但现有临床证据存在明显局限性:国际多中心研究样本量不足(如ASCEND-HF研究仅纳入7000例)、国内研究多为回顾性分析(累计样本<2000例)、缺乏生物标志物动态监测数据,导致循证医学证据等级偏低(IIb类推荐)。本研究采用单中心前瞻性对照设计,通过纳入104例符合ESC诊断标准的ADCHF患者,系统评估新活素对NT-proBNP水平、淤血评分、左室射血分数等核心指标的改善作用,同时监测肾功能、电解质等安全性指标。预期成果将指导临床用药选择。研究成果可直接转化为缩短住院周期(预计减少1.8天)、降低30天再住院率(目标值<18%),每年可为三级医院节省医疗成本约120万元,具有显著的卫生经济学价值。此外,通过动态监测Nt-proBNP等新型生物标志物,可揭示新活素改善心室重构的作用机制,为后续药物研发提供理论依据。  

Objectives of Study:

Acute exacerbation of chronic heart failure (ADCHF) is the main clinical manifestation in the terminal stage of cardiovascular diseases, characterized by high incidence, rehospitalization rate and mortality. Each year, the number of hospitalizations worldwide due to ADCHF exceeds one million, with a readjustment rate within 30 days as high as 25%. Direct medical expenses account for 2% to 3% of the total expenditure on cardiovascular diseases. The current clinical standard treatment plan mainly consists of diuretics, vasodilators and positive inotropic drugs, but there are serious side effects such as hypotension and deterioration of renal function. About 15% to 30% of patients develop treatment resistance. Recombinant human brain natriuretic peptide (Xinhuosu), as a vasodilator positive inotropic drug, improves hemodynamic disorders through dual mechanisms and theoretically has a higher safety threshold. However, the existing clinical evidence has obvious limitations: the sample size of international multi-center studies is insufficient (for example, the ASCEND-HF study only included 7,000 cases), most domestic studies are retrospective analyses (cumulative samples < 2,000 cases), and there is a lack of dynamic monitoring data of biomarkers, resulting in a relatively low level of evidence-based medical evidence (Class IIb recommendation). This study adopted a single-center prospective controlled design. By including 104 ADCHF patients who met the diagnostic criteria for ESC, the improvement effect of Xinhuosu on core indicators such as NT-proBNP level, congestion score, and left ventricular ejection fraction was systematically evaluated, while safety indicators such as renal function and electrolytes were monitored. The expected outcomes will guide the selection of clinical medications. The research results can be directly translated into shortening the hospitalization period (expected to be reduced by 1.8 days) and lowering the 30-day readmission rate (target value <18%), which can save about 1.2 million yuan in medical costs for tertiary hospitals each year, and have significant health economic value. In addition, by dynamically monitoring novel biomarkers such as Nt-proBNP, the mechanism by which Xinhuosin improves ventricular remodeling can be revealed, providing a theoretical basis for subsequent drug development.

干预措施:

在给予人重组脑利钠肽抗心衰的同时,给予限制入量的液体摄入方案干预:根据《中国心力衰竭诊断和治疗指南2018》,肺淤血、体循环淤血及水肿明显者应严格限制饮水量和静脉输液速度,无明显低血容量因素(如大出血、严重脱水、大汗淋漓等)者,摄入液体量控制在<1.5ml/d,保持每天出入量负平衡约500 ml,严重肺水肿者水负平衡为1000-2000 ml/d,甚至可达3000-5000ml/d,以减少水钠潴留,缓解症状。A组给予重组人脑利钠肽基础上,严格限制入量,液体摄入量严格控制在 <=1.5 ~2 L/天,钠摄入量严格控制在<2g/天。

干预措施代码:

Intervention:

While administering recombinant human brain natriuretic peptide for heart failure treatment, a fluid intake restriction protocol is implemented: According to the 2018 Chinese Guidelines for the Diagnosis and Treatment of Heart Failure, patients with obvious pulmonary congestion, systemic venous congestion, or edema should strictly limit oral water intake and intravenous infusion rates. For patients without evident hypovolemic factors (such as massive hemorrhage, severe dehydration, or profuse sweating), total daily fluid intake should be controlled to less than 1.5 L/day, aiming for a daily negative fluid balance of approximately 500 mL. In cases of severe pulmonary edema, the daily negative fluid balance should be 1000–2000 mL/day, and may even reach 3000–5000 mL/day, in order to reduce sodium and water retention and alleviate symptoms. Group A receives recombinant human brain natriuretic peptide along with strict fluid restriction, limiting total daily fluid intake to ≤1.5–2 L/day and sodium intake to <2 g/day.

干预措施:

在给予人重组脑利钠肽抗心衰的同时,给予宽容容量的液体摄入方案干预。对患者施以宽松容量管理的液体摄入方案,患者入组后,给予重组人脑利钠肽,用法:首先给予rhBNP 1.5 μg/kg,负荷剂量静脉推注 3~5 min,随后以 0.01-0.015 μg/kg/min速度静脉泵入维持72 h;联合宽松容量管理方法:维持总液体入量>35ml/kg/d,热量>25kcal/kg/d,前5天基础静脉补液为0.9%氯化钠注射液400ml+50%葡萄糖注射液100ml+氯化钾注射液1.5g,10%葡萄糖注射液1000ml+氯化钾1g,10%葡萄糖注射液250ml+葡萄糖酸钙2.0g+维生素c 2g;同时鼓励患者自主摄入,以纠正患者存在的高代谢所导致入量以及能量摄入不足

干预措施代码:

Intervention:

While administering recombinant human brain natriuretic peptide (rhBNP) for the treatment of heart failure, a liberal fluid management strategy is implemented. Upon enrollment, patients receive rhBNP as follows: an initial loading dose of 1.5 μg/kg administered by intravenous bolus over 3–5 minutes, followed by a continuous infusion at a rate of 0.01–0.015 μg/kg/min for 72 hours. This is combined with a liberal fluid management protocol: total daily fluid intake is maintained above 35 mL/kg/day, and caloric intake exceeds 25 kcal/kg/day. During the first five days, baseline intravenous fluid regimens include: 400 mL of 0.9% sodium chloride injection + 100 mL of 50% glucose injection + 1.5 g potassium chloride; 1000 mL of 10% glucose injection + 1 g potassium chloride; 250 mL of 10% glucose injection + 2.0 g calcium gluconate + 2 g vitamin C. Patients are also actively encouraged to increase oral intake to address inadequate fluid and energy intake resulting from hypermetabolism.
