Mortalidad y recurrencia de la enfermedad tromboembólica venosa en pacientes adultos: cohorte prospectiva

INTRODUCTION Venous thromboembolic disease (VTE) is a pathology that increases with age. RESULTS: 446 patients were included, 63% (292) were older than 65 years. Survival was lower in the elderly compared to the young (p 0.007), at 3 months 87% vs. 95% and at one year 73% vs. 87%, respectively. The elderly had a HRc1.71 and HR at 1.68. The overall recurrence was 5% (95% CI 3-8) at one month, 6% (95% CI 4-9) at 3 months, 8% (95% CI). 6-11) at one year and 13% (95% CI 9-18) at two years. No association was found between age and recurrence sub hazard 0.8 (CI 0.34-1.86). Bleeding occurred in 9% (39) of the patients. OBJECTIVE to compare the survival of the elderly and the young with a first episode of acute and symptomatic VTE. MATERIALS AND METHODS Prospective cohort of incident VTE cases included in the Institutional Registry of Venous Thromboembolic Disease (NCT01372514) of the Italian Hospital of Buenos Aires between 2012-2014, divided into young groups (17-64 years old) and elderly (65 years old). All the patients were followed annually to assess the time to recurrence (progression or new symptomatic event of VTE) as competitive events in the context of death and major bleeding. Raw (c) and adjusted (a) risks were presented. CONCLUSIONS The overall mortality in patients with confirmed VTE is higher in the elderly population. There were no differences in relation to the recurrence of VTE, or bleeding, and neither with age.
