The aim of this work was to study dynamics of new cases of hospital
thromboembolism of pulmonary artery branches (
TEPA) based on the registry data of Tomsk hospitals for 2003-2010 and to estimate applicability of recommendations of European Society of Cardiologists (2008) on diagnostics and treatment of
TEPA. Case records and autopsy protocols were available for analysis. The data were treated using Statistica for Windows 6.0 package. 5.04% of the deceased patients had
TEPA according to autopsy data. The discrepancy between clinical and pathoanatomical findings averaged 57.6%. In 2010,
TEPA was not diagnosed in 35.6% patients. The number of new cases of submassive
TEPA and
TEPA of small branches with the fatal outcome decreased to 40.7 and 48% since 2007 while the incidence of lethal massive
thromboembolism amounted to 68%. Its increase was especially notable among men after 2008. In 2003, 73.3% of the patients who died from
TEPA were women while it was the cause of death in 54.8% of men in 2010. The duration of
hospital stay was 0-16 (mean 8/1 +- 7.8) bed-days. Most patients (60.3%) had 3 or more risk factors. The frequency of TRPA relapses correlated with the presence of pericardial fluid (p = 0.039) and acute
myocardial infarction (p = 0.023). In 24.2% of the cases.
TEPA originated in heart chambers.
