Venous thromboembolism in patients with COVID-19.A prevalent and a preventable complication of the pandemic

摘要

Coronavirus disease 2019 or most commonly known as COVID-19 is a trending global infectious disease which a few months ago was affirmed as a global health emergency or a pandemic by the WHOEmergency Committee.The common symptoms manifested in this pandemic disease are high grade fever,cough,fatigue,shortness of breath and flu like symptom which can evolve into severe respiratory disorders such as pneumonia,acute respiratory distress syndrome(ARDS)and/or end-organ failure.Factors that contribute to the severity or high mortality rate in COVID-19 include old age,comorbidities like hypertension,diabetes,hyperlipidaemia,neutrophilia,and organ and coagulation dysfunction.Disseminated intravascular coagulation and other various coagulopathies including Venous thromboembolism have known to become a major contributing factor to high mortality rate.Venous thromboembolism is a disease which is a combination of deep vein thrombosis and pulmonary embolism.Prophylactic anticoagulation in patients prone to or with a pre-existing history of venous thromboembolism is associated with decreased mortality in severe COVID-19 pneumonia.This review article focuses upon COVID-19 and increased incidence of venous thromboembolism in patients infected by COVID-19 along with the role it has in high mortality rate in COVID-19 patients.
