概括
复发性血栓事件在男性和那些具有特异性初始事件的人中更为常见. 血栓过血症测试对治疗策略的影响有限,临床因素对抗凝血决定更为关键.
科学领域:
- 心血管医学 心血管医学
- 血液学 血液学 血液学
- 临床流行病学临床流行病学
背景情况:
- 辩论的是静脉血栓事件 (VTE) 的复发率和血栓友爱等危险因素的影响.
- 血栓过敏查对指导预防策略和抗凝药治疗持续时间的临床有用性仍然不清楚.
研究的目的:
- 为了确定第一个VTE之后的血栓事件的复发率.
- 确定复发的决定因素,包括血栓性异常,患者人口统计和治疗因素.
主要方法:
- 一项前性随访研究 (莱登血栓友爱症研究) 涉及474名连续患者 (18-70岁) 首次客观确认的血栓事件.
- 患者的平均随访时间为7.3年,评估基于血栓性风险因素,性别,初始事件类型和口服避孕药的使用的复发事件.
主要成果:
- 整体复发率为每1000个患者年25.9,在事件发生后的前两年发生率最高.
- 男性的复发风险比女性高2.7倍. 异常发病的初始事件增加了复发风险 (HR,1.9).
- 妇女使用口服避孕药增加了复发率. 血栓型异常显示出与复发风险的不同,往往不显著的关联 (例如,XI因子升高HR0.6;抗凝剂缺乏HR1.8).
结论:
- 血栓前异常似乎在VTE复发风险中发挥着有限的作用.
- 对血栓形成症的查对当前的预防策略的影响很小.
- 临床因素,而不是实验室异常,在指导抗凝治疗的持续时间方面更为重要.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Disorders of Hemostasis
2.8K
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Venous Thrombosis I: Introduction
834
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
470
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Venous Thrombosis III: Interprofessional Care
482
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Venous Thrombosis IV: Nursing Management
418
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...
