本文总结了21例无其它心肺疾患肺栓塞患者的临床特点。发现：（1）患者发病平均年龄41±12岁。（2）病程在一个月以内者6例（29％），一个月以上者15例（71％）。（3）呼吸困难是最常出现的症状（81％），呼吸困难和／或胸痛发生率为95％。（4）动脉血氧分压低于60mmHg占47％。（5）T波倒置是最常出现的心电图异常。（6）超声心动图异常发生率为93％。（7）胸部X线检查示肺不张和／或肺实质异常发生率为40％。（8）43％的患者有下肢静脉血栓证据。所有这些发现，虽然并非确诊肺栓塞的必不可少的要素，但应视为通过合理的分析，可以提高诊断肺栓塞敏感性和特异性的基础。
This article summarizes the clinical features of 21 patients with pulmonary embolism without other cardiopulmonary diseases. Found: (1) the average incidence of patients aged 41 ± 12 years old. (2) There were 6 cases (29%) with disease course within one month and 15 cases (71%) with more than one month. (3) Dyspnea was the most common symptom (81%), and dyspnea and / or chest pain was 95%. (4) arterial partial pressure of oxygen below 60mmHg accounted for 47%. (5) T wave inversion is the most common ECG abnormalities. (6) The incidence of echocardiography was 93%. (7) chest X-ray examination showed atelectasis and / or parenchymal abnormality rate was 40%. (8) 43% of the patients had evidence of venous thrombosis of the lower extremities. All of these findings, while not an essential element in the diagnosis of pulmonary embolism, should be considered as a basis for rational and sensitive diagnosis of pulmonary embolism.
