title: [Clinical picture of acute pulmonary embolism. Relations to the degree of vascular obstruction].
abstract: In 132 consecutive patients treated for pulmonary embolism, duration of symptoms, number of embolic episodes before the diagnosis, circulatory affection (stable circulation (n = 61), reversible shock (n = 60), circulatory collapse (n = 11), electrocardiographic findings and systolic pulmonary pressure (n = 60) were analysed in relation to 1) underlying diseases (orthopedic surgical patients (n = 43), gynecological-abdominal surgical patients (n = 22), preembolic healthy patients (n = 42), miscellaneous medical patients (n = 25)), and 2) the obstruction of the pulmonary vascular bed quantified by a scintigraphic or angiographic score. While embolic score did not differ between the groups of underlying diseases, preembolic healthy patients with deep vein trombosis (n = 30) had longer mean duration of symptoms (14 days), more embolic episodes, (1.7 episode) and higher pulmonary pressure (72 mmHg) than the material on an average with values of 7 days, 0.9 episodes and 57 mmHg, respectively (p less than 0.001). Among patients with reversible shock or circulatory collapse, half had at least one previous embolic episode, one fifth from two to four. Embolic score correlated well with the circulatory affection (p less than 0.001). A high pulmonary pressure correlated with long duration of symptoms and a high number of embolic episodes (p less than 0.002). Sinus tachycardia and electrocardiographic signs of acute right ventricular strain (complete and incomplete right bundle branch block, SIQIIITIII-pattern and inverted T-waves in V2-4) correlated positively to the circulatory affection and inversely to duration of symptoms and number of embolic episodes (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
