Abstract
BACKGROUND: Pulmonary embolism is a frequent cause of intra-hospital mortality. The survival of patients depends not only on the speed of diagnosis but also on the treatment initiated. OBJECTIVE: to evaluate the intra-hospital survival of patients with pulmonary embolism in the city of Kinshasa. METHODOLOGY: analytical cross-sectional study based on non-probability convenience sampling carried out in the city of Kinshasa; three hospitals selected for convenience on the basis of their technical platforms. The patients were judged to have had a pulmonary embolism after a chest CT angiography proved it. The data recorded on the Kobocollect site were exported in Excel format and analyzed with SPSS software version 23. The comparison of the means was made using the Student test and that frequencies with the Yates Chi-square test. The association was attributed by the calculation of the odds ratio and the survival presented according to the Cox regression. RESULTS: Eighty-nine cases or 63 women and 26 men were analyzed, the mean age was 64.4 ± 15.6 years. Individuals over 65 died more (ß=0.043 and p-Value of 0.01) the female sex multiplied by 1.38 the risk of death (DNS, p-Value = 0.478). Approximately 80% of patients were classified as PESI stage II or III. Starting Rivaroxaban from the outset does not show any difference with enoxaparin in terms of intra-hospital survival. CONCLUSION: Pulmonary embolism is a real problem in our environment, the age of more than 65 years and the female sex are factors of poor prognosis and predicted survival.
