The primary therapy for acute pulmonary embolism is anticoagulation with heparin and warfarin to prevent additional thromboembolism. Traditional teaching relegates the use of thrombolysis to the rare situation in which massive pulmonary embolism causes cardiogenic shock. Thrombolytic agents such as alteplase (recombinant tissue plasminogen activator) act on plasminogen by cleaving the peptide bond between arginine at position 560 and valine at position 561, thereby converting plasminogen to plasmin, which dissolves the embolus. Should we expand the indications for thrombolysis to encompass pulmonary embolism in patients with right ventricular dysfunction, even in the presence of normal systemic arterial pressure (see Figure. . .
