| Popis: | Transthoracic echocardiography is the most frequently used method for detection of impaired contractility of the left ventricle. In most cases, assessment of contractility is carried out visually “by eye”, what increases its subjectivity, is operator-dependent in nature and requires a high level of clinical training and experience of the researcher. Currently in the arsenal of a specialist in echocardiography for quantification of left ventricular contractility sometimes is used tissue Doppler echocardiography, however, this method requires special settings of the image (high frame rate, the allocation of zones of interest), depends on the scanning angle and on operator qualification, has high intra – and inter-operator variability, and significantly increases the duration of the study. Therefore, this method has not received wide clinical application. In the 2000s years an innovative technique of speckle tracking emerged, which, unlike tissue Doppler echocardiography is efficient, does not burden a researcher with time costs, has a low intra – and inter- operator variability, does not depend on scan angle. In recent years, this technology is actively implemented in clinical practice for detection of subclinical impairment of the functional state of the myocardium in different diseases and syndromes: arterial hypertension, ischemic heart disease, valvular defects, and congenital heart disease, heart failure, cardiomyopathy of different etiology. |
