Clinical and anamnestic characteristics and risk factors in patients with acute pulmonary embolism among residents of Kharkiv

Background. The purpose was the analysis of the features of the course and the leading factors in the development of pulmonary embolism. Materials and methods. During the period from November 1, 2019, to December 2020, inclusive, 188 patients with acute pulmonary embolism (PE), aged 46 to 80 years old, were hospitalized at the City Clinical Hospital 8 of the Kharkiv City Council; the average age was 62.9 ± 16.7 years. In-hospital mortality was 12.2 % (23 patients). The criterion for inclusion in the study was acute PE, which was diagnosed based on the results of multislice computed tomographic angiography of the pulmonary arteries (MCT angiography of the pulmonary arteries). All patients underwent a general clinical examination, the risk and prognosis were assessed based on the generally accepted scales, standard transthoracic echocardiography (EchoCG), and Doppler ultrasound examination of the veins of the lower extremities were performed. Results. The disease was diagnosed with the same frequency in men and women; there was no difference in age. Among the most significant and important risk factors for the development of pulmonary embolism are the history of venous thrombosis/embolism and active malignant oncological disease (43 and 35 %, respectively), while the less significant ones were advanced age, varicose veins of the lower extremities and arterial hypertension 47.9, 31.4 and 52.1 %, respectively. The vast majority (57.4 %) had a combination of 2 or more risk factors. Signs of right ventricular dysfunction according to MCT angiography of the pulmonary arteries and/or echocardiography were recorded in 45.7 % of patients. A high and medium-high risk of early death associated with acute PE was found in a significant percentage (71.8 %) of patients, which required the inclusion of a thrombolytic agent in the treatment strategy.
