Dyslipidemia as a long-term marker for survival in pulmonary embolism

Abstract

Objectives: To analyse survival rate after 24 months in consecutive patients with a diagnosis of PE as well as associated factors. Methods: Prospective cohort study during a follow-up period of two years in a series of consecutive patients with PE. Results: During the follow-up period, 34 out of 148 patients died (23%). Factors independently associated with reduced survival rate were: creatinine levels > 2 (OR, 8.8; 95% CI, 1.1 - 70.87), previous neoplasm (OR, 8.8; 95% CI, 3.69 - 20.98), dementia (OR, 6.85; 95% CI, 2.1 - 22.33) and dyslipidemia (OR, 5.07; 95% CI, 1.92 - 13.44). Forty four percent of the patients with dyslipidemia died vs. 20.8% of patients without this condition. Conclusions: In our study dyslipidemia shows as a long-term negative prognostic marker for survival in patients with EP. Resumo: Objetivos: Analisar a taxa de sobrevivência após 24 meses, em pacientes consecutivos com diagnóstico de PE, bem como fatores associados. Métodos: Estudo prospectivo durante um período de seguimento de dois anos em uma série consecutiva de pacientes com PE. Resultados: Durante o período de acompanhamento, 34 dos 148 pacientes morreram (23%). Fatores independentemente associados à reduzida taxa de sobrevivência foram: os níveis de creatinina> 2 (OR, 8,8; 95% CI, 1,1-70,87), neoplasia anterior (OR, 8,8; IC 95%, 3,69-20,98), demência (OR, 6,85; 95% CI, 2,1-22,33) e dislipidemia (OR, 5,07; IC 95%, 1,92-13,44). Quarenta e quatro por cento dos pacientes com dislipidemia morreram contra 20,8% dos pacientes sem essa condição. Conclusões: No nosso estudo, a dislipidemia mostra-se um marcador prognóstico negativo de longo prazo na sobrevida de pacientes com EP.
