Aim: to assess the results of speckle tracking echocardiography (STE) in patients of working age with acute inferior wall myocardial infarction (MI) in the early period after coronary stenting. Patients and Methods: STE was performed using EPIQ-7 Ultrasound Machine (Philips, USA) in 55 patients with acute inferior wall MI one week after percutaneous coronary intervention and 29 healthy individuals of working age. Patients with acute inferior wall MI were divided into two subgroups, i.e., with (n=45) or without (n=10) areas of local contractile impairment (dyskinesia, akinesia, hypokinesia). Results: the most common cause of MI was the occlusion of the right coronary artery (82.4% in subgroup 1 and 60% in subgroup 2) in multivascular involvement (84.4% and 90%. respectively). In patients with local contractile impairment, reduced left ventricular ejection fraction (EF) was reported in 28.9%, global longitudinal strain in 86.7%, and global circular strain in 76.7%. Meanwhile, in patients without local contractile impairment, left ventricular ejection fraction (LV EF) was within normal ranges, global longitudinal strain was reported in 100% and global circumferential strain in 70%. The presence and severity of local dysfunction did not affect the reduction in segmental strain (median varied from -9% to -15%). In inferior wall MI, the abnormal regional longitudinal strain of 6 LV segments (basal and mid inferoseptal, inferior, and inferolateral) was reported in both hypokinesia and normokinesia. Conclusions: ultrasound evaluation of systolic LV function using STE is characterized by greater diagnostic value compared to the measurement of EF only and objectifies the efficacy of surgery. Quantitative assessment of the recovery of both global and local systolic contractility is another advantage of STE allowing for personalized treatment.

All over the world cardiovascular diseases are one of the main reason of morbidity and mortality in the structure of non-communicable diseases, and myocardial infarction has a leading role. Markers of modern advanced ultrasound techniques, speckle tracking echocardiography, play significant role in the detection and assessment of cardiovascular disease. Deviation of them can detect myocardial ischemia, hypertrophy, dystrophy and infiltration, severe systemic diseases, cardiotoxicity of the drugs, etc. This technology significantly improves diagnostic capabilities of transthoracic echocardiography, it allows to assess myocardial function in all three planes (longitudinal, circumferential and radial), in which myocardium moves during cardiac cycle. Speckle tracking echocardiography can determine the volume of myocardial damage, differentiate subendocardial and transmural myocardial infarction, identify viable and fibrous areas of the myocardium, that is confirmed by the results of magnetic resonance imaging. Besides, this method helps to detect and assess mechanical dyssynchrony and also predict the risk of pathological left ventricular remodeling and life-threatening adverse cardiovascular events (arrhythmias, increasing of heart failure, recurrent myocardial infarction, stroke, death, etc.), that is important for patients with acute myocardial infarction to identify high-risk patients. The most studied markers of this technique are longitudinal, circumferential and radial strain, mechanical dispersion and postsystolic shortening. Markers of this ultrasound technique significantly complete other markers of transthoracic echocardiography, such as left ventricular ejection fraction, to assess risk stratification of cardiovascular complications. The value of speckle-tracking echocardiography markers has been demonstrated alone or in combination with other markers.

The aims of this study were i) to evaluate mitral and aortic annuli excursion, and aortomitral angle (AMA) during the cardiac cycle in healthy adults using two-dimensional speckle tracking echocardiography, ii) to assess two annuli dynamics and coupling behaviors as an integral, and iii) to detect the relation between two annuli and left ventricular ejection fraction (LVEF). A total of 74 healthy adults underwent transthoracic echocardiography. In the parasternal long-axis view, a number of points were extracted, including right coronary aortic annular, aortomitral fibrous junction, and posterior mitral annular points. The annuli excursion and AMA were measured using a speckle tracking-derived software during the cardiac cycle. During the isovolumic contraction and the isovolumic relaxation phase, annuli excursion and AMA remain stable for a short time. During the systole, annuli excursion increased sharply to the maximum, while AMA narrowed quickly to the minimum value. During the diastole, there are three patterns of decrease in annuli excursion and AMA expansion in different phases. The annuli excursion of three points correlates well with the LVEF (right coronary aortic annulus excursion, r=0.71, P<0.05; non-coronary aortic annulus excursion, r=0.70, P<0.05; posterior mitral annulus excursion, r=0.82, P<0.05). Moreover, there are positive correlations between annuli excursion and the variation of AMA (r=0.60, P<0.05). The annuli excursion and AMA have various regular patterns in healthy adults. The interactions of mitral and aortic annuli correlate with the left ventricular function. Our findings may have relevance to the evaluation of left ventricular function and presurgical planning of patients with valvular diseases.
