|
Objectives of Study: |
To explore the efficacy and safety of of different doses of rivaroxaban in the treatment of left ventricular thrombus caused by coronary heart disease in the real world. And to evaluate the relationship between different doses of rivaroxaban and death and MACE. |

|
药物成份或治疗方案详述: |
药物成份:利伐沙班及华法林钠 给药方案: 正常剂量利伐沙班组:利伐沙班 15mg qd或20mg qd 小剂量利伐沙班组:≤10mg/天(用法包括2.5mg bid;5mg qd;5mg bid;10mg qd) 华法林组:在开始服用华法林时,应用低分子肝素进行桥接,并每3-4天监测一次INR,待INR控制在2-3时,停用低分子肝素,并继续定期监测INR,真实世界中,由于多方面原因,可能导致INR未及时监测,药物剂量未及时调整,导致INR不达标的情况。 无抗凝组:未使用上述口服抗凝药物。 注:抗血小板药物(如阿司匹林,氯吡格雷,替格瑞洛等)的使用,由医生自行决定采用单联抗血小板或双联抗血小板或无抗血小板药物的应用。 |

Description for medicine or protocol of treatment in detail: |

|
纳入标准: |
冠心病所致的LVT患者(左室血栓的形成发生于低流速、低剪切力环境中)。 有两次以上TTE随访的患者。 病人未在住院期间发生死亡。 |
||||||||||||||||||||||
|
Inclusion criteria |
Patients with LVT caused by coronary heart disease (The formation of LVT occurring in a low-flow and low-shear environment). Patients with more than two TTE follow-ups. Patients discharged alive. |
||||||||||||||||||||||
|
排除标准: |
非冠心病所致的LVT患者。 涉及机械循环辅助装置的LVT患者(此类患者LVT的形成主要是通过接触途径介导的,这与冠心病的LVT的形成发生在低流量和低剪切力的环境中不同)。 患者在此次住院期间死亡或在口服抗凝血药生效之前死亡。 失访、拒绝随访或经胸超声心动图随访≤两次的患者(院外死亡者除外)。 LVT在患者仅接受皮下注射低分子肝素时消失。 使用其他口服抗凝剂如达比加群、阿哌沙班等的患者。 患有严重肾功能衰竭[肌酐清除率(CrCl)<15 ml/min]和严重肝病(转氨酶超过参考值3倍以上)的患者,一过性原因导致的严重肝肾功能损害除外。 由于2D-TTE技术有限,无法准确评估LVT存在的患者。 妊娠和确诊的血液系统疾病(轻度或中度贫血除外)。 |
||||||||||||||||||||||
|
Exclusion criteria: |
Patients with LVT caused by non-coronary heart disease. Patients with LVT involving mechanical circulatory assist devices (The formation of LVT is predominantly in contact pathway but not mediated in a low-flow and low-shear environment ). Patients died during the index hospitalization or died before oral anticoagulants taking effect. Patients who were lost to follow up, refused to follow up or followed up with less than two times of TTE. Patients with LVT disappeared during only subcutaneous LMWH injection. Patients with other oral anticoagulants such as dabigatran, apixaban. Patients with severe renal failure [creatinine clearance (CrCl) < 15 mL/min] and severe liver diseases (transaminase exceeded the reference value by more than 3 times).However, severe liver and kidney function damage caused by transient reasons were not excluded. Patients with technically limited 2D-TTE, which prevented assessment of the presence of thrombus. Pregnancy and confirmed hematologic diseases (except mild or moderate anemia). |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
研究开始之前对每一位研究员进行培训,确保每位研究者理解和接收研究方案,并严格按照研究方案进行临床研究。 我们应用excel表记录病人的人口学信息、临床资料(血尿便、心脏超声、手术信息等,如果病人进行了超声左室造影、延迟心脏强化CT或核磁,也一并记录)、用药信息及药物调整信息。并记录病人超声随访结果、随访过程中发生的出血、栓塞、死亡及MACE信息。为保证录入数据的准确性及一致性,我门对excel表中每个数据的录入进行了“有效性/分类”限制。 每一个词条的录入需要经两位研究员进行核查校正以保证数据录入的准确性。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Before the start of the study, training should be provided to each researcher to ensure that they understand and accept the research protocol, and strictly follow the protocol for clinical research. We use Excel spreadsheets to record patients' demographic information, clinical data (blood, urine, stool, cardiac ultrasound, procedure information, etc. If the patient has undergone left ventricular contrast imaging, delayed cardiac enhanced CT or MRI, they will also be recorded), medication information, and medication adjustment information. We will also record the patient's ultrasound follow-up results, bleeding, embolism, death, and MACE information that occurred during the follow-up process.To ensure the accuracy and consistency of the entered data, we have imposed "validity/classification" restrictions on the entry of each data in the Excel spreadsheet. Each entry needs to be verified and corrected by two researchers to ensure the accuracy of data entry. |
