Multicenter Study Clinical Trial
Clinical characteristics of patients with acute pulmonary embolism stratified according to their presenting syndromes.
The purpose of this investigation is to determine the characteristics of the history, physical examination, chest radiograph, and ECG, and the ventilation/perfusion (V/Q) lung scan probability in patients with pulmonary embolism (PE) stratified according to their presenting syndrome. ⋯ Many of the findings in the various syndromes of PE can be understood in terms of the severity of PE as it increases from mild with the pulmonary infarction syndrome to moderate with the isolated dyspnea syndrome to severe with circulatory collapse. The prevalence of various clinical and laboratory characteristics of patients with the syndrome of pulmonary infarction, isolated dyspnea, or circulatory collapse may give clues to the diagnosis or suggest characteristics that may reduce the likelihood of inadvertently discarding the diagnosis of PE.
