OBJECTIVES/SPECIFIC AIMS: To investigate the prognostic value of left ventricular mitral annular longitudinal displacement (LD) measured with color tissue Doppler imaging (TDI) in a large population suffering from acute coronary syndrome (ACS). METHODS/STUDY POPULATION: In total, 501 ACS patients underwent an echocardiography within 9 days after a percutaneous coronary intervention. Regional LD was obtained from the 6 mitral annular regions with TDI and GLD was calculated as an average. RESULTS/ANTICIPATED RESULTS: During a median follow-up time of 4.4 years 46 ACS patients suffered CVD. Mean value of GLD in the population was 8.11mm (±2.4). GLD and LD obtained from the inferior wall remained significant independent predictors after multivariate adjustment for clinical parameters, GLD (HR: 1.43, 95% CI: 1.12–1.82, p=0.014, per 1mm decrease), inferior LD (HR: 1.38, 95% CI: 1.14–1.66, p=0.001). Furthermore, inferior wall LD was the primary source of prognostic information in GLD since only inferior LD remained significant when both measures were included in the same model: GLD (HR: 0.95, 95% CI: 0.64–1.40, p=0.781); inferior LD (HR: 1.60, 95% CI: 1.15–2.22, p=0.005). Of all walls, only inferior wall LD remained as an independent predictor after multivariate adjustment. DISCUSSION/SIGNIFICANCE OF IMPACT: GLD provides independent prognostic information in ACS patients over and beyond all conventional echocardiographic measures. Regional inferior LD was the primary source of prognostic information gained from GLD. GLD proved to be a better predictor of cardiovascular events than conventional echocardiographic measures. This could lead to better risk stratification in the clinical setting and open up for earlier intervention in high-risk individuals.

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.

And Function

Right ventricular (RV) performance plays an important role in the morbidity and mortality of patients with left ventricular dysfunction, congenital heart disease, and pulmonary hypertension. Assessment of RV size, function, and haemodynamics has been challenging because of its complex geometry. Conventional two-dimensional echocardiography is the modality of choice for assessment of RV function in clinical practice. Recent developments in echocardiography have provided several new techniques for assessment of RV dimensions and function, include tissue Doppler imaging, speckle-tracking imaging, and volumetric three-dimensional imaging. However, specific training, expensive dedicated equipment, and extensive clinical validation are still required. Doppler methods interrogating tricuspid inflow and pulmonary artery flow velocities, which are influenced by changes in pre- and afterload conditions, may not provide robust prognostic information for clinical decision-making. This chapter addresses the role of the various echocardiographic modalities used to assess the RV and pulmonary circulation. Special emphasis has been placed on technical considerations, limitations, and pitfalls of image acquisition and analysis.

Objective: Tissue tracking (TT), obtained by tissue Doppler imaging (TDI), can be utilized to assess the mitral annular longitudinal displacement (LD) during systole. However, the prognostic utility of regional LD in patients with heart failure with reduced ejection fraction (HFrEF) is unknown. Methods: Transthoracic echocardiographic examinations from 911 patients with HFrEF were retrieved from a heart failure clinic’s database. The exams were performed from 2005 to 2013. The echocardiographic images were subsequently analyzed obtaining conventional echocardiographic measurements. Regional LD was obtained from the three apical TDI projections with sampling at six mitral annular sites located at the anterior, lateral, posterior, inferior, septal and anteroseptal myocardial walls. Results: During a median follow-up period of 40 months 150 (16.4 %) patients died. Patients that died had significantly lower LVEF (23.3% vs 28.3%, p<0.001) and lower regional LD in all six mitral annular sites (Figure). Many conventional echocardiographic parameters presented as predictors of mortality (LVEF, LVMI, LAVI, E, E/e’, deceleration time and TAPSE). However, only LD at the septal and inferior annular sites remained independent predictors of mortality in cox proportional-hazards models after adjusting for age, gender, BMI, total cholesterol, heart rate, atrial fibrillation, non-independent diabetes mellitus and the aforementioned conventional echocardiographic predictors (Figure). In addition, the septal and the inferior sites had the highest Harrell’s C-statistic of all the echocardiographic predictors (0.70 and 72, respectively). Conclusion: In patients with severe heart failure, septal and inferior LD are independent predictors of all-cause mortality. Furthermore, septal and inferior LD proved to be superior prognosticators when compared to all the conventional echocardiographic parameters.

Objective. The aim of the research under consideration was to study the dynamics of a local systolic-diastolic function of patients with various ischemic heart disease (IHD) progressions after survival of an acute coronary syndrome (ACS) provided there are residual stenoses of coronary arteries.Materials and Methods. There were 112 patients suffering from ACS who took part in the research. The diagnosis was verified (acute myocardial infarction or unstable angina) in accordance with the recommendations of European Society of Cardiology (ESC). All patients were divided into two groups depending on the occurrence of major acute cardiac events (MACE): 59 patients with aggravated IHD progression and 152 patients with non-aggravated course. Echo-cardiography was performed on a scanner Philips iE33 (the Netherlands) with a consideration to systolic and diastolic functions parameters of a left ventricle. Quantitative analysis of the left ventricle was executed in the mode of Tissue Doppler Imaging (TDI) and according to the method of tracing the patches of the ultra-sound image gray scale (ST).Results. In the course of the aggravated IHD a decrease in systolic-diastolic function of left ventricle has been discovered. It has been found out that the amount of the systolic peak of longitudinal strain of the left ventricle anteroseptal wall less than 12% is associated with a greater extent of coronary atherosclerosis and aggravated progression of IHD. TDI and ST methods have enabled to reveal that in the course of non-aggravated IHD the contractility and the diastolic function of the left ventricle anteroseptal wall improve in combination with the increase in the contractility of the left ventricle inferolateral wall. During an aggravated IHD progression the contractility and diastolic function of the left ventricle anteresoptal wall decreases without an increase in contractility and diastolic function of the inferior and inferolateral walls of the left ventricle. The reason for such results might be a progressing myocardial ischemia of the left ventricle anteroseptal wall despite the sufficient anterior interventricular artery stenting. The presence of the relevant residual stenoses of the circumflex and right coronary arteries increases the possibility of the aggravated IHD progressing especially by the end of the fourth year of observation.Conclusion. The disbalance of the local contractility of anterior, inferior and inferolateral left ventricle walls in the course of aggravated IHD is connected with the CA residual stenoses presence and forwards the decrease in global systolic-diastolic function of the left ventricle. The final results can serve as a foundation for optimization of recommendations for performing PCI on the patients with multivessel disease of CA.

BackgroundTissue Doppler imaging (TDI) can be used to measure the mitral annular longitudinal displacement (LD) during systole. However, the prognostic utility of global and regional LD in patients with heart failure with reduced ejection fraction (HFrEF) is unknown.MethodsEchocardiographic examinations from 907 patients with HFrEF were analysed obtaining conventional echocardiographic measurements. Regional LD was obtained from colour TDI projections in six mitral annular regions and global LD was calculated as an average.ResultsMean age was 67 years, 26.9% were women and mean left ventricular ejection fraction was 27%. During a median follow-up period of 40 months, 150 (16.5 %) patients died. The risk of dying increased with decreasing tertile of global LD and was approximately five times higher for patients in the lowest tertile compared with the highest (1. tertile vs 3. tertile, HR 4.9, 95% CI: 3.0 to 7.9, p<0.001).Global LD was a significant independent predictor of mortality after adjusting for age, gender, body mass index, pacemaker, heart rate, atrial fibrillation, diabetes and conventional echocardiographic measures and global longitudinal strain: HR 1.16 (95% CI: 1.00 to 1.34, p=0.044) per 1 mm decrease.For regional measures, inferior LD was also a significant independent predictor in the multivariable model: HR 1.16 (95% CI: 1.04 to 1.29, p=0.006) and adding inferior LD to the conventional measures yielded a significant increase in Harrell’s C-statistic (95% CI: 0.75 to 0.78, p=0.009).ConclusionIn patients with HFrEF, global and inferior LD are independent predictors of all-cause mortality. Furthermore, inferior LD proved to be a significant prognosticator when compared with all the conventional echocardiographic parameters.
