Echocardiographic Evaluation of Left Ventricular Diastolic Function in Patients with Acute Pulmonary Embolism
The pathophysiological changes of acute pulmonary embolism are due to the reduction of anatomical pulmonary
vascular bed caused by embolism, and pulmonary vasospasm caused by nerve, humoral factors and hypoxemia,
resulting in a reduction in functional pulmonary vascular area, which leads to increased vascular resistance,
Eventually, the pulmonary artery pressure rises. The emergence of three-dimensional echocardiography is
another major breakthrough in ultrasound technology. It is based on the matrix probe technology. The steering
of the sound beam, the formation of the three-dimensional image database, and the matrix transducer are all
controlled by the computer. According to the multi-directional sound beam rapid scanning Works on principle.
This article discusses the evaluation of left ventricular diastolic function in patients with acute pulmonary
embolism by echocardiography. In this study, PASP, TAPSE and 3D echocardiographic measurements RVEF
and PER have a good correlation (P <0.01), and RVEF and PER have a good correlation (P <0.01) 3D
echocardiography It can early and accurately evaluate the changes of left ventricular diastolic function in
patients with acute pulmonary embolism. Provide an objective basis for clinical monitoring of the severity of
APE patients and evaluation of efficacy.
