Answer

Anticoagulant treatment decreases mortality to less than 5%. At 5 days of anticoagulant therapy, 36% of lung scan defects are resolved; at 2 weeks, 52% are resolved; and at 3 months, 73% are resolved. Most patients treated with anticoagulants do not develop long-term sequelae upon follow-up evaluation. The mortality in patients with undiagnosed pulmonary embolism is 30%.
