The results of the morphological and functional evaluation of the left ventricular in athletes of different sports disciplines are presented in this paper. The aim of the study was to assess morphological and functional condition of the left ventricular in athletes with the emphasis on the evaluation of the diastolic function including the use of tissue Doppler. Methods: 231 athletes of different sports disciplines were examined. All athletes included in this study underwent comprehensive transthoracal echocardiography by means of Doppler study and tissue Doppler. Results: This study revealed the difference in heart morphology between athletes of different sports disciplines. Parameters of the diastolic function of the left ventricular are not significantly differ between athletes of different sports disciplines. The diastolic function was not impaired in athletes with mild hypertrophy of the left ventricular. Violation of diastolic function occur in athletes with complaints of extreme fatigue after exercise. Method of tissue Doppler allows to detect signs of diastolic function impairment in athletes with formally "normal" mitral blood flow. Conclusions: 1. In athletes with small and border myocardial hypertrophy of the left ventricle is not observed violations of diastolic function of the left ventricular myocardium, which indicates the adaptive nature of the appearance of a small hypertrophy. 2. The authors suggest that the impairment of the diastolic function of the left ventricular is linked with the chronic overload of cardiovascular system. 3. The use of tissue Doppler allows to determine the signs of diastolic function impairment in athletes with visually normal mitral blood flow. 4. The authors consider enough check tissue Doppler imaging speed of displacement of the lateral part of the mitral annulus, since the check in other segments rarely gives new information, significantly extending the time of the study. 5. The authors also suggest that it is necessary to assess diastolic function by means of tissue Doppler in athletes with the E/A ratio less than 1.5.

Abstract Background Malnourished children endure many changes in body composition and lose heart and skeletal muscle mass. Diastolic dysfunction is one of the major causes of heart failure with preserved ejection fraction. Aim To assess left ventricular systolic and diastolic functions in children with severe acute malnutrition using tissue Doppler imaging technique and to evaluate the effect of nutritional rehabilitation. Patients and Methods A follow-up case-control study conducted on 60 severely malnourished children (WHZ < -3SD) and 120 age and sex-matched healthy children as a control group. Tissue Doppler imaging (TDI) was done for all included malnourished children at admission and for control to measure left ventricular systolic and diastolic functions. Nutritional rehabilitation was done according to WHO protocol and tissue doppler was repeated after rehabilitation when (WHZ > -2SD) to detect any changes in systolic or diastolic functions. Results Systolic function was normal in malnourished children and control. Grade I diastolic dysfunction was detected in 40% and grade II in 30% of severely malnourished children in comparison to 100% normal diastolic function in control group. No correlations between diastolic dysfunction and either anthropometric measurements, electrolyte disturbances or Hb% in malnourished children before nutritional rehabilitation. Mortality from sepsis with associated ventricular dysfunction grade II documented in 3.3% of malnourished children. After nutritional rehabilitation diastolic function improved significantly as 65.6% of children attained normal diastolic function, 31% grade1 and 3.4% grade II. Positive correlations between diastolic function and WAZ, HAZ, WHZ and MUAC after rehabilitation. Conclusion Severe acute malnutrition affects diastolic function in children which is reversible in most of these cases with rehabilitation. TDI is an easy and practical method for detection and follow-up of ventricular function in malnourished children.

The evaluation of diastolic function in patients with reduced (HFREF) or preserved (HFPEF) left ventricular (LV) ejection fraction is important as it carries both diagnostic and prognostic information. In daily practice, this is most frequently done by standard echocardiographic techniques, including the evaluation of LV mass and LA volumes, as well as transmitral and pulmonary venous PW Doppler, CW Doppler for evaluation of the IVRT, and tissue Doppler imaging of the septal and lateral annular velocities. This permits grading the severity of diastolic dysfunction, which is related to outcome and may be used to estimate LV filling pressures. The latter needs further validation, especially in patients with HFPEF. Newer echocardiographic and cardiac magnetic resonance techniques, including myocardial deformation measurements during diastole, LV twist and untwisting, and parameters of left atrial function, are promising and will hopefully in the future help clinicians to make a more precise evaluation of diastolic function and filling pressures in heart failure patients.

Left atrial (LA) functional analysis has an established role in assessing left ventricular diastolic function. The current standard echocardiographic parameters used to study left ventricular diastolic function include pulsed-wave Doppler mitral inflow analysis, tissue Doppler imaging measurements, and LA dimension estimation. However, the above-mentioned parameters do not directly quantify LA performance. Deformation studies using strain and strain-rate imaging to assess LA function were validated in previous research, but this technique is not currently used in routine clinical practice. This review discusses the history, importance, and pitfalls of strain technology for the analysis of LA mechanics.

Deposits of myocardial fibrosis are the principal cause of myocardial dysfunction and poor prognosis in the patients with systemic sclerosis. Our aim was to assess whether there are changes in regional function of the left ventricular myocardium in female patients with systemic sclerosis without clinical signs and symptoms of cardiovascular disease. The study included 23 female patients with systemic sclerosis (without cardiovascular disease and with normal global systolic and diastolic function of the left ventricle) and 21 healthy female controls. In both groups, pulsed wave tissue Doppler imaging was done at rest and during exercise stress test echocardiography. The myocardial function was assessed from the basal segments in systola and diastola. The level achieved and duration of exercise tests were significantly reduced in the patients with systemic sclerosis compared to the controls (P<0.001 for both). The patients had significantly lower baseline regional systolic (P<0.02) and diastolic (P<0.001) myocardial functions, which became even more evident after the exercise test. During the test, those with systemic sclerosis demonstrated a smaller increase of systolic (20.6%) and diastolic (6.5%) function compared to the controls (systolic by 32.3% and diastolic by 25.0%). Quantification of regional function of the left ventricular myocardium using pulsed wave tissue Doppler imaging demonstrated an impaired systolic and diastolic myocardial function in the female patients with systemic sclerosis who had no clinical signs and symptoms of a cardiovascular disease.
