The prognosis of patients with PE depends on two factors: the underlying disease state and appropriate diagnosis and treatment. Approximately 10% of patients who develop pulmonary embolism die within the first hour, and 30% die subsequently from recurrent embolism. Mortality for acute pulmonary embolism can be broken down into two categories: massive pulmonary embolism and nonmassive pulmonary embolism.
