Pharmacotherapy of pulmonary embolism.
Pulmonary embolism (PE) and deep vein thrombosis are common causes of illness and death. The pharmacological approach to pulmonary embolism includes the use of anticoagulants, unfractionated heparin for the acute phase, and oral anticoagulants for prophylaxis. In massive PE, the use of thrombolytic agents is suggested to reduce systemic hypotension and right ventricular failure and increase cardiac output. Thrombolytic agents act on pulmonary vascular obstruction. In clinical practice, thrombolytic therapy is recommended in case of massive embolism with haemodynamic failure. Recent studies suggest the use of thrombolytic drugs in patients with normal systemic blood pressure who show right ventricular dysfunction at echocardiographic examination. A large randomised trial on lytic agents in submassive PE is therefore needed. Anticoagulants were primarily indicated for prevention of recurrences. Due to the development of low molecular weight heparin, the role of anticoagulants needs to be re-evaluated.
