VTE is a common cardiovascular disorder with significant morbidity and mortality. [3] [4] [5] VTE can present with various symptoms, such as painful leg swelling, chest pain, dyspnea, hemoptysis, syncope, and even death, depending on the location and extent of the thrombus.
In 2021, the American College of Chest Physicians offered one testing-related recommendation in its venous thromboembolism guidelines. [40] They recommended to consider positive D-dimer in the decision to continue or discontinue anticoagulation. Positive D-dimer may suggest that the ongoing thrombotic tendency has not fully resolved.
American evidence-based clinical guidelines were published in 2016 for the treatment of VTE. [42] In the UK, guidelines by the National Institute for Health and Care Excellence (NICE) were published in 2012, updated in 2020. [43] These guidelines do not cover rare forms of thrombosis, for which an individualized approach is often needed. [5]
A 2021 review found that low molecular weight heparin (LMWH) was superior to unfractionated heparin in the initial treatment of venous thromboembolism for people with cancer. [3] There are medication-based interventions and non-medication-based interventions. [4]
Venous thromboembolism (VTE), a common risk factor, is present at much higher rates in those over the age of 70 (three times higher compared to those aged 45 to 69). [27] This is likely due to there being a generally lower level of activity among the elderly, resulting in higher rates of immobility and obesity. [27]
A 2005 article concluded that heterozygous carriers who take combined birth control pills are at a 15-fold increased risk of venous thromboembolism, [12] while carriers also heterozygous with factor V Leiden have an approximate 20-fold higher risk. [2]

In 2021 a condition resembling HIT but without heparin exposure was described to explain unusual post-vaccination embolic and thrombotic events after the Oxford–AstraZeneca COVID-19 vaccine. [20] [21] [22] It is a rare adverse event (1:1 million to 1:100,000) resulting from COVID-19 vaccines (particularly adenoviral vector vaccines). This is ...
