[The relation between acute embolism and thromboembolic pulmonary hypertension]

The author analyzes the natural course of acute pulmonary embolism and its progression. Treated acute pulmonary embolism has a favourable long-term prognosis which is negatively influenced only by further diseases. While acute pulmonary embolism is the third most frequent cardiovascular disease--the incidence of chronic thromboembolic pulmonary hypertension is very rare and accounts only for 0.38% in necroptic material.
