"Optimal treatment of PE is still poorly understood and there is a need for a coordinated institutional approach to this complex, life-threatening problem," said Kenneth Rosenfield, M.D., study co-lead principal investigator and section head, Vascular Medicine and Intervention, Division of Cardiology, Massachusetts General Hospital, Boston. "The lead investigators of the trial are pleased to collaborate with the PERT Consortium, which is committed to evidence-driven therapy and is proud to take part in the HI-PEITHO study, aiming to advance the care of patients with PE."
