[1] . In this study, the authors have compared the parameters such as age, sex, comorbidities, laboratory findings, use of anticoagulants and radiological findings in Covid-19 patients with and without acute pulmonary embolism. It has been emphasized that increased levels of D-dimer, worsening in clinical symptoms and abnormal blood levels during the follow-up should alert the clinician. Active smoking is known as a major risk factor in venous thromboembolism [2] . In addition, it has been shown that obesity increases the risk of venous thromboembolism [3] . In this study, we did not seen any information about smoking and obesity status of the patients. We believe that these factors may greatly affect the results of the study.
