The following are key points to remember from this review on the management of pulmonary embolism (PE): PE is a major contributor to global disease burden, including.In rare cases, arranging for placement of a venous filter may be appropriate if the patient is not a candidate for thrombolytic therapy.Current guidelines for patients with acute. pulmonary embolism,.Thrombolytic therapy should be used in patients with acute PE associated with hypotension (systolic BP.Current guidelines for patients with acute PE recommend LMWH over IV UFH (grade 2C) and over SC UFH (grade 2B).
A prothrombin time ratio is expressed as an INR and is monitored to assess the adequacy of warfarin therapy.Posteroanterior and lateral chest radiograph findings are normal, which is the usual finding in patients with pulmonary embolism.Thrombolytic therapy is not recommended for most patients with acute PE not associated with hypotension.The value of ischemia-modified albumin compared with d-dimer in the diagnosis of pulmonary embolism.

Few patients with venous thromboembolism require large doses of heparin for achieving an optimal activated partial thromboplastin time (aPTT).Because warfarin therapy results in bleeding, future studies should determine whether less intense warfarin therapy is effective in preventing recurrences of pulmonary embolism.Prognostic importance of hyponatremia in patients with acute pulmonary embolism.
Hyperosmolar Therapy for Increased Intracranial Pressure (Review).Data from a pooled analysis of the EINSTEIN-PE and EINSTEIN-DVT studies in the treatment of DVT or pulmonary embolism suggest that rivaroxaban is as effective in preventing VTE recurrence as administration of enoxaparin followed by a vitamin-K antagonist.Pulmonary arterial hypertension (PAH), updated medical therapy guideline ACCP 2007.Apixaban, dabigatran, rivaroxaban, and edoxaban are alternatives to warfarin for prophylaxis and treatment of PE.
