Prevalence of Venous Thromboembolism

  • Common disorder, associated with high morbidity and mortality
  • VTE occurs at an annual incidence of ~1 in 1000 adults
  • Clinical manifestations are deep vein thrombosis (DVT) and its major complication pulmonary embolism (PE)
  • 2/3 of episodes manifest as DVT and 1/3 as PE with or without DVT
  • Rates increase sharply after age 45
  • Rates are slightly higer in men than in women
  • Different incidences among ethnic groups (higher rates in Caucasians than in Asians or Hispanics)
  • Major outcomes: death, recurrence, post-thrombotic syndrome and major bleeding due to anticoagulation
  • Death occurs within one month of an episode in about 6% of those with DVT and 10% of those with PE
