Brief Summary

Stroke is an independent risk factor for venous thrombosis (VTE), which leads to a significant increase in the mortality and disability rate after stroke. For patients with high risk factors for VTE such as advanced age, paralysis, infection, dehydration, etc., the incidence of death and disability is higher. Studies have shown that the incidence of deep vein thrombosis in bedridden ischemic stroke patients is about 20%, and the incidence of pulmonary embolism is about 2%, and causes 10% of post-stroke deaths. In order to prevent the occurrence of VTE, the American Heart Association, the American Stroke Association, the Cerebrovascular Disease Group of the Neurology Branch of the Chinese Medical Association, etc. pointed out in the guidelines that heparin or low molecular weight heparin should be used for stroke patients with "restricted mobility" or "incapable mobility" to prevent VTE. For patients with evidence of thrombosis or symptoms of DVT, antithrombotic therapy should be initiated immediately. Paradoxically, ischemic stroke significantly increases the risk of cerebral hemorrhage. Besides There is an increased risk of primary intracerebral hemorrhage (ICH) associated with aspirin or antiplatelet agent monotherapy and it is difficult to achieve a balance between preventing blood clots and reducing the risk of bleeding complications. In addition, stroke patients are elderly and have speech and intellectual impairment, and the non-specific symptoms and signs of intracranial hemorrhage caused by improper antithrombotic therapy make the rate of misdiagnosis and missed diagnosis extremely high. Therefore, clarifying the clinical characteristics of stroke patients with VTE and launching targeted interventions to effectively balance the risk of anti-thrombosis and bleeding have become the key to improving the prognosis of patients.

This study is based on real-world data to study the bleeding risk and antithrombotic treatment options in VaS (1) the risk factors associated with hemorrhage in patients with VTE after stroke; and (2) the characteristics and pharmacotherapeutics regimen of high-risk populations with VTE after stroke; and(3) the Optimal antithrombotic treatment regimen for patients with VTE after stroke, including the timing of starting and stopping the antithrombotic treatment, selection of varieties, dosage, and course of treatment, etc.
