概括
患有心房动 (AF) 和癌症的患者面临类似的中风风险,但出血风险更高. 恶性病症不应降低AF患者的抗凝血治疗建议.
科学领域:
- 心脏病学 心脏病学
- 在瘤学瘤学.
- 流行病学 流行病学
背景情况:
- 恶性瘤对心房患者中风风险的独立影响尚不清楚.
- 了解这种关联对于管理患有癌症的AF患者至关重要.
研究的目的:
- 在被诊断为AF的个体中调查恶性瘤与中风和出血风险之间的关系.
- 为有癌症史的AF患者提供基于证据的抗凝管理指南.
主要方法:
- 一项基于人口的队列研究使用了66岁及以上的新诊断AF的个人管理数据集.
- 在AF诊断前五年内诊断出恶性瘤的患者与基于关键临床因素的无癌症对照组相匹配.
- 使用因果特异回归分析来确定中风和出血的危险比率,并根据抗凝状态进行调整.
主要成果:
- 在近20万名AF患者中,12.5%的患者先前患有恶性瘤.
- 在一个超过43,000名患者的匹配队列中,恶性瘤与类似的中风风险相关 (HR:1.01),但与无癌症对照组相比,出血风险明显更高 (HR:1.45).
- 亚组分析显示,肺癌患者中风风险增加,乳腺癌或淋巴瘤患者的出血风险没有增加.
结论:
- 与没有癌症的人相比,患有AF和恶性瘤的人通常会经历类似的中风风险,但患有高出血风险.
- 这些发现表明,恶性瘤的存在不应降低AF患者启动或继续抗凝治疗的推值.
- 对特定癌症类型的进一步研究可能会完善风险分层和治疗策略.

Disorders of Hemostasis
686
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.

Anticoagulant Drugs: Low-Molecular-Weight Heparins

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...
