Dyspnea After an Acute Intermediate-Risk Pulmonary Embolism: A Case-Based Approach to Evaluation and Treatment.

Exercise intolerance after acute pulmonary embolism may be caused by residual pulmonary vascular obstruction, which presents as chronic thromboembolic pulmonary disease with or without pulmonary hypertension. We present a case highlighting a systematic approach to evaluating functional limitations due to residual pulmonary vascular obstruction, emphasizing the utility of cardiopulmonary exercise testing.
