Chronic Thromboembolic Pulmonary Hypertension (CTEPH) Diagnosis Algorithm Defined as pulmonary hypertension (mPAP > 25) > 6 months after initial PE. The typical flow of diagnosis is that patients with symptoms of exercise intolerance, dyspnea get an echo which shows pulmonary hypertension, and then eventually get CTPE or V/Q scan to evaluate. Note that this diagnosis is often overlooked given there may be no overt history of PE #CTEPH #Diagnosis #Algorithm #Pulmonary #Hypertension
