Title: Cooperative Investigation Plan for Home Treatment of Pulmonary Embolism
Brief Summary: The best management in selected patients of pulmonary Embolism (PE) should be at home. The efficacy and safety treatment´s at home versus at hospital should be similar and quality of life should be better. Our purpose is to demostrate that Low weight molecular heparin (LWMH) at home for PE is at least as effective and safe at home as at hospital
