Comparative analysis of cases of embolic lesions of the systemic circulation
AbstractThe aim - comparative analysis of known and potential risk factors for arterial embolism of the systemic circulation of various localizations.
Materials and methods. Retrospective cohort study of risk factors for development of embolic stroke by continuous sampling according to the materials of the case histories and autopsy protocols autopsy 10 254 deaths in hospitals in Tomsk from 01.01.2008 to 31.12.2016. Identified 340 (3.3%) cases of embolism of the systemic circulation, which were divided according to the localization of embolic occlusion to 2 groups. The 1st group amounted to 228 (68%) deaths, embolism of cerebral vessels. The 2nd group were included 107 (32%) deaths embolism of the abdominal cavity and retroperitoneal space. In all cases embolic lesions of the cerebral vessels is verified ischemic cerebral infarction.
The results. According to the findings, a significant effect on the risk of embolic ischemic stroke provided by a number of factors. Thus, the presence of arterial hypertension of II degrees to 7 times increased likelihood of embolic stroke, the presence of permanent atrial fibrillation - 2 times. In addition, it is discovered that the patient has chronic heart failure stage 2A almost 3 times increased risk of cerebral thromboembolic complications. Anemia was also a statistically significant factor in the development of cerebral embolism.
Conclusion. The majority of deaths in the group with cerebral embolism were multiple potential risk factors of embolic complications. Identified a serious impact on the risk of arterial embolism permanent form of atrial fibrillation, chronic heart failure phase 2, hypertension, and anemia.
