研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

1. 高龄PE患者DOACs药物浓度与临床结局(出血、血栓复发)的相关性及安全有效浓度范围。 2. DOACs浓度与常规凝血指标(如PT、APTT)的关联性,以及用于疗效监测的敏感指标。 3. 结合患者个体特征(年龄、肾功能、基因多态性)建立高龄PE患者DOACs剂量调整预测模型。  

Objectives of Study:

1. Correlation between DOACs plasma concentrations and clinical outcomes (bleeding, thrombosis recurrence) in elderly patients with pulmonary embolism (PE), and the safe and effective concentration range.2. Association between DOACs concentrations and routine coagulation parameters (e.g., PT, APTT), and identification of sensitive indicators for therapeutic monitoring.3. Development of a predictive model for dose adjustment of DOACs in elderly PE patients by integrating individual patient characteristics (age, renal function, genetic polymorphisms).

纳入标准:

Inclusion criteria

排除标准:

1. 预期寿命<3个月; 2. 存在活动性大出血或明显出血倾向(如近期消化道出血、颅内出血史未评估稳定等),或研究者判断抗凝风险不可接受者; 3. 重度肝功能不全(如Child-Pugh C)或伴凝血功能明显异常且非抗凝所致者; 4. 重度肾功能不全(如eGFR<15 mL/min/1.73m^2或需透析)导致DOAC使用不适宜者; 5. 血小板显著减少(如<50×10^9/L)或其他严重血液系统疾病影响出血/凝血评估者; 6. 妊娠或哺乳期; 7. 无法按研究要求完成固定时间服药与采血(依从性差、无法随访等)者。

Exclusion criteria:

1. Life expectancy < 3 months; 2. Presence of active major bleeding or obvious bleeding tendency (e.g., recent gastrointestinal bleeding, history of intracranial hemorrhage not assessed as stable, etc.), or judged by the investigator to have unacceptable risk of anticoagulation; 3. Severe liver dysfunction (e.g., Child-Pugh Class C) or significant coagulation abnormalities not attributed to anticoagulation; 4. Severe renal dysfunction (e.g., eGFR < 15 mL/min/1.73m^2 or requiring dialysis) making the use of direct oral anticoagulants (DOACs) inappropriate; 5. Significant thrombocytopenia (e.g., platelet count < 50 × 10^9/L) or other severe hematological disorders affecting bleeding/coagulation assessment; 6. Pregnancy or breastfeeding; 7. Inability to adhere to fixed medication and blood sampling schedules as required by the study (e.g., poor compliance, inability to follow up, etc.).
