The aim – to determine the risk factors of an unfavorable prognosis in patients with pulmonary embolism (PE) depending on gender.
Materials and methods. A retrospective analysis of the data of 635 patients with a verified diagnosis of PE according to multispiral computed tomographic angiography (MSCT-angiography) of pulmonary vessels and/or according to autopsy results, who were consecutively hospitalized at Kharkiv City Clinical Hospital No. 8 for the period from January 1, 2017 to January 1, 2023. Patients were divided into two groups: IA group included patients with high-risk acute PE who were discharged from the hospital, IВ group – patients with high-risk acute PE who died during the hospital period. Clinical and anamnestic, laboratory and instrumental indicators were analyzed, statistical processing of data depending on gender was carried out.
Results and discussion. When analyzing the obtained data, it was established that in the group of deceased patients with a high risk there was probably a higher proportion of women (72 % at p=0.014). Deceased males had more severe clinical manifestations than deceased females, as evidenced by significantly lower SpO2 values (p=0.022) and larger right ventricular dimensions on echocardiography (p=0.036). In turn, such a risk factor of PE as obesity was more common in women than in men (61.1 % vs. 28.6 % at p=0.039). In order to determine independent factors associated with in-hospital mortality in high-risk PE patients in women, we conducted uni- and multifactorial logistic regression analysis of the influence of the studied factors. Since the small number of deceased men in the sample (n=14) does not allow us to draw reasonable conclusions, the analysis of factors affecting mortality is given only for the group of women. Factors associated with in-hospital death were the presence of arterial hypertension in the anamnesis (p=0.043), a decrease in systolic blood pressure (p=0.0003) in the acute period, and the localization of a thrombus at the bifurcation of the pulmonary arteries (p=0.012). After performing the regression analysis, we derived a formula for individual prediction of the risk of in-hospital death for gender with high-risk PE. Using the ROC analysis, it was established that the sensitivity of the obtained prognostic formula is 75.0 %; specificity – 83.9 (area under the ROC curve 0.867; 95 % confidence interval 0.762–0.938, p<0.0001). The formula developed by us includes available general clinical indicators and allows specifying the individual risk of in-hospital mortality for female patients with high-risk PE.
Conclusions. The results of a comparative analysis of two subgroups of patients with high-risk PE who died, depending on gender, showed that men were more likely to have lower SpO2 values and larger right ventricular sizes according to echocardiography. In turn, such risk factors as obesity were more common in women than in men. According to multivariate logistic regression analysis, additional independent factors that are associated with the development of death during the hospital period in women with high-risk PE are the presence of arterial hypertension in the anamnesis, a decrease in systolic blood pressure in the acute period, and the localization of a thrombus at the bifurcation of the pulmonary arteriesof. Proposed formula, according to which Y>0.5 establishes an additional high risk of in-hospital death in women with high-risk PE.
