Relationship of prognostic criteria of pulmonary embolism

The establishment of prognostic criteria for the outcome of pulmonary embolism is an important aspect for creating an algorithm for optimal tactics of treatment of patients. Aims: to determine the relationship of prognostic criteria of pulmonary embolism in order to establish the most significant of them. Materials and methods: the study included 428 patients with pulmonary embolism, of whom 21 died, and 50 developed chronic thromboembolic pulmonary hypertension in the long-term follow-up period. An analysis was carried out to establish the most significant criteria for adverse outcomes and their relationship. Results: the significance of adverse outcomes of pulmonary embolism for criteria such as the presence of hypotension with a decrease in systolic blood pressure of less than 90 mm Hg, an increase in the plasma concentration of troponin, echocardiography signs of overload of the right ventricle was confirmed. At the same time, the presence of right ventricular overload criteria in echocardiography is more significant than an increase in the level of plasma troponin concentration, the most common of them are an increase in the ratio of the size of the right ventricle to the left more than 0.9 and an increase in systolic pressure in the pulmonary artery more than 50 mm Hg. Conclusions: the most significant echocardiography prognostic criterion in patients with pulmonary embolism is an increase in the ratio of the size of the right ventricle to the left more than 0.9.
