Pulmonary embolism: assessment of the severity and prognosis of the outcome of the disease

Predicting and preventing the development of death and chronic thromboembolic hypertension in patients with pulmonary embolism is one of the urgent problems of modern medicine. The introduction into clinical practice of stratification of the risk of early death from pulmonary embolism has made it possible to optimize the treatment of these patients in many ways. However, uncertainty remains in the choice of the volume of therapy in patients with moderate risk of early death. What underlies the often incorrect choice of treatment tactics and, as a result, the development of chronic thromboembolic pulmonary hypertension in these patients, more often than in other patients. Many researchers see ways to solve this problem in establishing new echocardiographic criteria for the severity of pulmonary embolism. This article analyzes modern literary data and the results of their own research. The superiority of determining the pressure gradient on the pulmonary artery valve, calculated on the basis of measuring the volume of the heart ejected into the aorta in one systole during echocardiography, over most widely used parameters is shown
