ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the application of two-dimensional ultrasound speckle tracking imaging (STI) in assessment of myocardial torsion and left ventricular function for patients with chronic pulmonary heart disease (CPHD).</p><p><b>METHODS</b>Thirty six patients with CPHD and 38 normal subjects were enrolled in the study,and STI examinations were performed. The left ventricular short-axis views (mitral level,apical level) were observed,the rotation angles of the standardized time point were measured at each short-axis views and the corresponding left ventricular torsion angles were calculated. Simultaneously, the basal rotation peak, apical rotation peak, left ventricular twist peak, end-systolic basal rotation value, end-systolic apical rotation value and end-systolic left ventricular twist value were recorded. The correlations of left ventricular ejection fraction (LVEF) with left ventricular torsion peak, end-systolic left ventricular twist value in patients were analyzed.</p><p><b>RESULTS</b>Compared to normal controls, the basal rotation peak, apical rotation peak, left ventricular twist peak, end-systolic basal rotation value, end-systolic apical rotation value and end-systolic left ventricular twist value were significantly lower (P<0.01) in CPHD patients. The LVEF was highly correlated with left ventricular twist peak and end-systolic left ventricular twist value in CPHD patients (r=0.967, 0.952,P<0.001).</p><p><b>CONCLUSION</b>STI is sensitive to detect left ventricular myocardial torsion change; left ventricular torsion peak and end-systolic left ventricular twist value can be used to assess the left ventricular function in patients with CPHD.</p>
