This disease is determined by several factors, however, according to the head of the Department of Pulmonology of the Kaunas Clinics of the Health Sciences Hospital of the University of Lithuania, prof. Miliauskas transparent, there is no presumption that vaccines against COVID-19 infection are associated with pulmonary embolism.
Teacher. S. Miliauskas explains that all the blood in the human body flows from the venous system through the lungs, emitting carbon dioxide and saturating it with oxygen. When blood clots form in the veins due to certain health problems (damage to the blood vessel wall, blood composition, increased blood clotting), they can break off and travel to the lungs with blood.
These mobile clots that block various blood vessels in the lungs are called emboli. The larger the blood clot in the blood vessel, the larger the embolus travels to the lungs and blocks a larger portion of the blood vessels in the lungs. Although inhaled air enters the part of the human lungs affected by emboli, the body does not get oxygen from there. Clogged blood vessels in the lungs increase blood pressure, overload the right ventricle, and in particularly severe cases, obstructive shock can kill a person.
Small clots that enter the lungs usually dissolve on their own, so a person may not feel any symptoms. However, if the blood vessels in the lungs are blocked by large emboli and the state of the cardiovascular system is not good due to other diseases, the person begins to lack of air. Shortness of breath, chest pain, increased heart rate, possible coughing up blood, loss of consciousness. If these symptoms occur, you should contact your healthcare provider immediately.
“There is currently no presumption that vaccines against COVID-19 infection can cause pulmonary embolism and we do not have that data. We see blood clotting problems when a person has a severe form of COVID-19 disease. Below , patients are given prophylactic anticoagulants. All the COVID-19 vaccines used in Lithuania are safe and cannot cause the disease itself, they create immunity that protects the body “, emphasizes Professor S. Miliauskas.
Referring to the risk factors for pulmonary embolism, remember that deep vein thrombosis and pulmonary embolism are clinical manifestations of a vascular disease called venous thromboembolism. However, the biggest risk factor for this disease is the various orthopedic surgeries and injuries. Also, the chances of pulmonary embolism are increased due to oncological diseases, some chemotherapeutic drugs, myocardial infarction, hormone replacement therapy, oral contraceptives, chronic heart and lung diseases, etc.
To protect yourself against pulmonary embolism, the most important thing is to stay physically active and get enough fluids. People who are at high risk of developing or who already have a pulmonary embolism are given medications to reduce blood clotting. In case of pulmonary embolism, these drugs are usually prescribed for three months to a year, but some patients must take blood clotting inhibitors for life, says the head of the Kaunas Pulmonology Clinic. S. Miliauskas.
