Pulmonary embolism outcome: a prospective evaluation of CT pulmonary angiographic clot burden score and ECG score.

Objective: The purpose of this study was to establish whether a correlation exists between the CT pulmonary angiographic clot burden score, the ECG score at diagnosis, and the 12-month mortality rate among patients diagnosed with pulmonary embolism.

Subjects And Methods: A total of 523 consecutive patients who underwent CT pulmonary angiography for a suspected moderate to high pretest probability of pulmonary embolism were recruited from March 2003 to October 2004. There were 105 patients with positive CT pulmonary angiography examinations.
