肺栓塞(pulmonarye mbodism,PE)是一种较常见的危害人类健康的重要肺血管疾病,也是引起突然呼吸困难的典型疾患,有时可伴有咳嗽、胸膜性胸痛。估计美国每年约60万以上的人发生肺栓塞,造成约10万人死亡,其发病率仅次于冠心病和高血压,死亡率仅次于肿瘤和心肌梗塞,已居临床死亡原因的第三位[1]。近年来的流行病学资料表明,在我国,PE已成为一种常见病[2]。 Pulmonary embolism (PE) is a common and important pulmonary vascular disease that is endangering human health. It is also a typical condition that causes sudden breathing problems, sometimes associated with cough and pleural chest pain. It is estimated that about 600,000 or more people in the United States will develop pulmonary embolism each year, resulting in about 100,000 deaths. The incidence is second only to coronary heart disease and hypertension, the second leading cause of death after cancer and myocardial infarction, ranking the third in the cause of clinical death Bit [1]. Epidemiological data in recent years show that in our country, PE has become a common disease [2].
