ABSTRACT
BACKGROUND: Exact benefits of currently recommended close monitoring in intermediate high risk acute pulmonary embolism (PE) patients are unknown. METHODS: This prospective observational cohort study determined clinical characteristics, and disease course of intermediate high risk acute PE patients in an academic hospital setting . Frequency of hemodynamic deterioration, use of rescue reperfusion therapy and PE related mortality, were outcomes of interest. RESULTS: Of 98 intermediate high risk PE patients included for analysis, 81 patients (83%) were closely monitored. Two deteriorated hemodynamically and were treated with rescue reperfusion therapy. One patient survived after this. CONCLUSIONS: In these 98 intermediate high risk PE patients, hemodynamic deterioration occurred in three patients and rescue reperfusion therapy of two closely monitored patients led to survival of one. Underlining the need for better recognition of patients benefitting from and research in the optimal way of close monitoring.
