  • Title: [The traps of pulmonary embolism].
    Author: Morpurgo M.
    Journal: Ann Cardiol Angeiol (Paris); 1998 Nov; 47(9):633-6. PubMed ID: 9864559.
    Abstract:
    The clinical diagnosis of pulmonary embolism (PE), even massive, remains difficult and perplexing. In our hospital, the percentage of exact clinical diagnoses has not significantly changed over recent years, with a false-negative rate of 78%, and a false-positive rate of 2%. In approximately 20% of cases, autopsy showed several emboli and pulmonary infarctions of various ages, indicating recurrent embolic episodes. The diseases most frequently associated were cardiac diseases (51%) and tumours (24%). Pneumonia considerably decreases the probability of an exact diagnosis of PE; hospitalisation in the Cardiology department or Intensive Care Unit increased the probability of this diagnosis. While the numerous diagnostic algorithms recently proposed have a limited value, the process integrating clinical and instrumental data in order to establish a prospective clinical probability, should facilitate identification of acute PE in live patients.
