研究目的: |
1.主要目的:为接受心脏手术的患者开发和验证个体化平均动脉压 (MAP) 目标预测框架,并评估其在降低主要不良心脑血管事件 (MACCE) 风险和改善术后预后方面的有效性。 2.次要目标: (1) 比较临床实践中个性化 MAP 靶向引导管理与常规血压管理的依从性水平。 (2) 评估个性化 MAP 目标与临床结果之间的关联,包括 ECMO/IABP 使用、术后急性肾损伤、心力衰竭、中风和全因死亡率。 (3) 评估基于模型的血液动力学管理对 ICU 住院时间、再入院率和血管活性药物使用的影响。 3.探索性目标: (1) 探讨临床亚组 (如慢性高血压患者、射出分率降低的患者和老年患者) 对个体化 MAP 目标反应的差异。 (2) 评估模型预测的个体化 MAP 与实时生理参数 (如心率、卒中量和全身总外周阻力) 之间的动态耦合关系。 (3) 探讨在未来临床决策支持系统 (CDSS) 中应用这种动态精确血液动力学管理框架的可行性和潜在价值。 |

Objectives of Study: |
1. Primary Objective: To develop and validate an individualized mean arterial pressure (MAP) target prediction framework for patients undergoing cardiac surgery, and to evaluate its effectiveness in reducing the risk of major adverse cardiovascular and cerebrovascular events (MACCE) and improving postoperative outcomes. 2. Secondary Objectives: (1) Compare the adherence levels between personalized MAP-targeted guided management and routine blood pressure management in clinical practice. (2) Assess the association between individualized MAP targets and clinical outcomes, including ECMO/IABP use, postoperative acute kidney injury, heart failure, stroke, and all-cause mortality. (3) Evaluate the impact of model-based hemodynamic management on ICU length of stay, readmission rates, and vasoactive drug use. 3. Exploratory Objectives: (1) Explore the differences in responses to individualized MAP targets among clinical subgroups (such as patients with chronic hypertension, reduced ejection fraction, and elderly patients). (2) Assess the dynamic coupling between model-predicted individualized MAP and real-time physiological parameters (such as heart rate, stroke volume, and systemic total peripheral resistance). (3) Explore the feasibility and potential value of applying this dynamic precision hemodynamic management framework in future clinical decision support systems (CDSS). |
