研究目的: |
主要研究心脏瓣膜置换术后患者华法林桥接低分子肝素是否获益更高,次要初步探索经过血栓风险分层,高血栓风险人群是否桥接治疗获益更高。心脏瓣膜术后是否存在抗凝血酶缺乏症. |

Objectives of Study: |
Primary Objective: To investigate whether bridging therapy with low-molecular-weight heparin (LMWH) during warfarin initiation yields greater clinical benefits for patients after cardiac valve replacement surgery.Secondary Objective: To preliminarily explore, based on thrombotic risk stratification, whether high-thrombotic-risk populations derive greater benefit from such bridging therapy.Additional Exploratory Focus: To examine the presence of antithrombin deficiency in patients following cardiac valve surgery. |
