【摘要】肺动脉栓塞(Plumonary Embolism, PE)是指内源性或外源性栓子堵塞肺动脉及其分支引起肺循环和呼吸功能障碍的临床和病理生理综合征。近年来临床实践证明PE是危害人类健康的常见病、多发病之一。我国目前尚无确切的PE流行病学资料，但现有资料表明其发病率不低。如果不及时进行抗凝治疗，PE死亡率可高达30%～36%，及时有效的抗凝治疗可使死亡率降至2.5%～8.0%，因此早期诊断是降低死亡率、改善预后的关键。

    【Abstract】Pulmonary artery embolism (Plumonary Embolism, PE) is refers to the endogenous or the exogenetic embolus jamming pulmonary artery and the branch causes the pulmonary circulation and the breath function barrier clinical and the pathology physiology syndrome. In recent years the clinical practice proved PE is harms the human health common disease, frequently-occurring diseases one. Our country at present still not accurate PE epidemiology material, but the existence information indicated that its disease incidence rate is not low. If is not prompt carries on the antifreeze treatment, the PE mortality rate may reach as high as 30%~36%, the prompt effective antifreeze treatment may cause the mortality rate to drop to 2.5%~8.0%, therefore the early diagnosis is cuts the mortality rate, the improvement prognosis key. ......
