Comparative StudyReversible left ventricular regional non-uniformity quantified by speckle-tracking displacement and strain imaging in patients with acute pulmonary embolism.
The aim of this study was to investigate the impact of acute right ventricular pressure overload (RVPO) on left ventricular (LV) function and regional uniformity using speckle-tracking displacement and strain analyses in patients with acute pulmonary embolism (PE). ⋯ Acute RVPO induces reversal LV regional uniformities, which are closely associated with reduced LV function and abnormal geometry of the left ventricle, and radial LV wall motion coordination plays a key role in the short-term regulation of cardiac output in patients with acute PE.
