Introduction. Heart failure with preserved left ventricular ejection fraction (HFPEF) is an epidemiologically serious disease. Noninvasive diagnosis of HFPEF remains challenging. The current diagnosis is based on evidence of diastolic dysfunction, albeit systolic dysfunction is also present but not included in the diagnostic algorithm. The aim of this study was to analyze the longitudinal (long), circumferential (circ) and radial (rad) component of systolic left ventricular (LV) function in patients with exertional dyspnea of unexplained etiology and normal left ventricular ejection fraction (LVEF). Methods. One hundred and twenty-two patients with exertional dyspnea of unexplained etiology and normal LVEF and 21 healthy controls, underwent echocardiography examination at rest and at the end of symptom-limited exercise. We analysed the longitudinal, circumferential and radial deformation of myocardium using two dimensional speckle tracking echocardiography in all subjects. Results. Patients with exertional dyspnea and preserved LVEF were divided into group A1 (46 patients meeting the criteria for the diagnosis HFPEF) and group A2 (76 patients without HFPEF). Group A1 had significantly worse longitudinal and circumferential systolic LV function than group A2. Subjects in group A1 compared to group A2 showed significantly different strain rates during atrial contraction (SR A), circ and ratio of peak early trans-mitral flow velocity (E) and strain rate E wave (E / SR E) circ. Multivariate logistic regression analysis showed that the SR parameter A circ is an independent predictor of HFPEF (odds ratio 0.550, 95% confidence interval: 0.370 -0.817, P value 0.003). Conclusion. Longitudinal and circumferential LV deformation was significantly more impaired in patients with HFPEF than in patients with exertional dyspnea without HFPEF. In patients with exertional dyspnea and normal LVEF, the value of SRA circ appears to be a significant and independent predictor of HFPEF. This parameter may, in the future complement the diagnostic algorithm for HFPEF.

Оце-ниваемый с ее помощью показатель глобальной продольной деформации миокарда более чувствителен к ранним изменениям сократимо-сти левого желудочка, чем фракция выброса. Диагностические возможности speckle tracking эхокардиографии нашли отражение в клини-ческих рекомендациях и согласительных документах Европейского общества кардиологов (ESC), Европейской ассоциации специалистов по методам визуализации сердечно-сосудистой системы (EACVI) и Американского общества эхокардиографии (ASE). Целью данной статьи яв-ляется изложение основных принципов speckle tracking эхокардиографии и возможностей клинического применения этой новой техноло-гии. Уделено внимание использованию speckle tracking эхокардиографии при сердечной недостаточности, коронарной патологии и инфаркте миокарда, гипертрофии левого желудочка при артериальной гипертензии, гипертрофической кардиомиопатии и амилоидозе сердца, кла-панных пороках сердца, констриктивном перикардите и эффекте кардиотоксичности при лечении онкопатологии.Ключевые слова: speckle tracking, эхокардиография, деформация миокарда, дисфункция миокарда, заболевания сердца. Speckle-tracking echocardiography is promising modern technique for evaluation of structural and functional changes in the myocardium. It evaluates the indicator of global longitudinal myocardial deformation, which is more sensitive than ejection fraction to early changes of left ventricular contractility. The diagnostic capabilities of speckle tracking echocardiography are reflected in clinical recommendations and consensus statements of European Society of Cardiology (ESC), European Association of Cardiovascular Imaging (EACVI) and American Society of Echocardiography (ASE). The aim of this paper is describe basic principles of speckle tracking echocardiography and clinical applications of this new technology. Attention is paid to the use of speckle tracking echocardiography in such heart pathologies as heart failure, coronary heart disease and myocardial infarction, left ventricular hypertrophy in arterial hypertension, hypertrophic cardiomyopathy and amyloidosis of the heart, valvular heart disease, constrictive pericarditis and cancer therapy-induced cardiotoxicity.Keywords: speckle tracking, echocardiography, myocardial strain, myocardial dysfunction, heart diseases. ВведениеСерьезные успехи в развитии сердечно-сосудистой визуализации с помощью ультразвука в последние десятилетия способствовали не только формированию интереса кардиологов к оценке функции миокарда, но и расширению представлений о физиологии сердца.

“…Recent studies using speckletracking echocardiography have reported that LV contraction is first impaired in the longitudinal direction in patients with cardiovascular risk factors [13][14][15][16]. Therefore, strain is a measure reflecting regional systolic function and has been used to detect subclinical myocardial dysfunction in a number of cardiac conditions.…”

Background: Strain ST-T changes on Electrocardiography (ECG) is a well-recognized marker of the presence and severity of Left Ventricular (LV) hypertrophy, which is usually associated with subendocardial dysfunction. However, the relationship between ST-T change and subendocardial dysfunction in hypertensive patients is unknown. Recently, two-dimensional speckle-tracking echocardiography has been used to define myocardial deformation parameters of the LV segment. Herein, we assessed subendocardial dysfunction patients with strain ST-T changes on electrocardiogram using two-dimensional speckle-tracking echocardiography.
