Disease monitoring in the 2-year period following the incident pulmonary embolism event. CTA = computed tomographic angiography; ECHO = echocardiogram; ICD-9-CM = International Classification of Disease, Ninth Revision, Clinical Modification; PAG = pulmonary angiography; PH = pulmonary hypertension; RHC = right heart catheterization; VQ = ventilation/perfusion scan. *The 10 prespecified PH symptoms (with ICD-9-CM codes in parenthesis) include syncope (780.2), malaise and fatigue (780.7), dyspnea (786.0), hemoptysis (786.3), chest pain (786.5), dizziness/ vertigo (780.4), gait abnormality (781.2), cardiomegaly (429.3), ascites (789.3), and peripheral edema (782.3).
