Changes of Cardiopulmonary Function After Thrombolysis in Patients With Pulmonary Embolism

Study Overview
=================
Brief Summary
-----------------
The investigators expect to enroll 50 acute pulmonary embolism patients treated with thrombolysis in two hospitals. Dynamic changes of cardiopulmonary function after thrombolysis are detected to evaluate which indicators can quickly reflect the effectiveness of thrombolysis.

Detailed Description
-----------------
About 50 acute pulmonary embolism(APE) patients treated with thrombolysis are enrolled in the First Affiliated Hospital with Nanjing Medical University and Nanjing Drum Town Hospital from January 1, 2020, to December 31, 2021. According to the 2019 ESC guideline, the standards for thrombolysis in APE patients are as follows: within 2 weeks of onset; high-risk pulmonary embolism; medium-high-risk pulmonary embolism with symptoms of aggravation. Investigators dynamically monitor cardiopulmonary function of participants after thrombolysis, including blood pressure, heart rate, respiratory rate, blood gas analysis, 2-dimensional echocardiography (left and right ventricular diameter, pulmonary artery pressure, interventricular septum) and laboratory tests (cTnT,pro-BNP).participants are divided into two groups: thrombolytic success group and thrombolytic failure group according the previously reported criterion which is evaluated 48h after thrombolysis. Cardiopulmonary characteristics are analyzed to seek accurate and rapid index to reflect success of thrombolysis.
