To the editor： The prognosis of in-hospital and out-of-hospital cardiac arrest （CA） is awfully poor. Most causes are reported tothromboembolism diseases, i.e. massive pulmonary embolism （MPE） and acute myocardial infarction （AM1）. Systemic thrombolysis during cardiopulmonary resuscitation （CPR） is still controversial, for tear of potentially lethal hemorrhage.
