Management of pulmonary embolism at a large academic hospital.

The initial management of patients presenting with acute pulmonary embolism (PE) is individualized based on hemodynamic status and other prognostic factors. Patients at low risk of adverse outcomes are treated conservatively with anticoagulation, whereas high-risk and selected intermediate-risk patients should be considered for advanced interventions. Seeking to better understand local practice patterns, we retrospectively reviewed 196 cases of acute PE diagnosed in the emergency department of Baylor University Medical Center over a 12-month period. Given the available data, we classified 86 cases as low risk, 101 as intermediate risk, and 9 as high risk for early mortality. Four patients with high-risk PE and 11 patients with intermediate-risk PE were treated with thrombolytic therapy. Central embolus location, right ventricular dilation on computed tomography, and right ventricular strain on electrocardiogram were associated with the use of thrombolytic therapy in the intermediate-risk group. In total, 9 patients died and 11 suffered major bleeding. Patients with acute PE are a remarkably heterogeneous group with wide variations in workup, treatment, and outcomes.
