“…113) which was newer than these listed in the guidelines [13]. Castel et al reported that upgrades of speckle tracking software were associated with significant changes in GLS values [38]. It is worth to mention that sample sizes in HUNT and Tromsø studies were much larger than in the other studies.…”

The early detection of subclinical myocardial dysfunction can contribute to the treatment and prevention of heart failure (HF). The aim of the study was to (i) describe myocardial global longitudinal strain (GLS) patterns in a large general population sample from Norway and their relation to established cardiovascular disease (CVD) risk factors; (ii) to determine its normal thresholds in healthy individuals and (iii) ascertain the relation of myocardial GLS to stage A subclinical heart failure (SAHF). Methods: Participants (n=1855) of the 7 th survey of the population-based Tromsø Study of Norway (2015-2016) with GLS measurements were studied. Linear and logistic regression models were used for assessment of the associations between CVD risk factors and GLS. Results: Mean GLS (SD) in healthy participants was-15.9 (2.7)% in men and-17.8 (3.1)% in women. Among healthy subjects, defined as those without known cardiovascular diseases and comorbidities, GLS declined with age. An increase of systolic blood pressure (SBP) of 10 mm Hg was associated with a 0.2% GLS reduction. Myocardial GLS in individuals with SAHF was 1.2% lower than in participants without SAHF (p<0.001). Conclusion: Mean myocardial GLS declines with age in both sexes, both in a general population and in the healthy subsample. SBP increase associated with GLS decline in women. Our findings indicate high sensitivity of GLS for early subclinical stages of HF.

“…Echocardiograms obtained with the use of Philips echocardiography machines were excluded because of reservations about intervendor variability of the STE measures, especially of regional measurements. 16,17 STE analysis was performed on the first available 4-chamber images with adequate image quality and a frame rate of ! 40 Hz (median frame rate 56 [interquartile range (IQR) 47-65] Hz).…”

“…Regardless of the efforts invested in the development of STE methods, further work is still needed to increase its inter-vendor and inter-observer repeatability as well as spatial and temporal resolution in order to broaden its range of applications. 5–8 The conducted research has shown that strain values obtained clinically are a subject to observer 9 and manufacturer 10,11 dependency, which poses a visible problem in the field. 12 Available methods offer estimations of longitudinal, circumferential, and radial strains—LS, CS, and RS respectively, for the entire wall, for predefined segments of the ventricle, or even for separate layers of the segments: endocardial, midwall, and epicardial.…”

Segmentation Enhanced Elastic Image Registration for 2D Speckle Tracking Echocardiography—Performance Study In Silico

Although the two dimensional Speckle Tracking Echocardiography has gained a strong position among medical diagnostic techniques in cardiology, it still requires further developments to improve its repeatability and reliability. Few works have attempted to incorporate the left ventricle segmentation results in the process of displacements and strain estimation to improve its performance. We proposed the use of mask information as an additional penalty in the elastic image registration based displacements estimation. This approach was studied using a short axis view synthetic echocardiographic data, segmented using an active contour method. The obtained masks were distorted to a different degree, using different methods to assess the influence of the segmentation quality on the displacements and strain estimation process. The results of displacements and circumferential strain estimations show, that even though the method is dependent on the mask quality, the potential loss in accuracy due to the poor segmentation quality is much lower than the potential accuracy gain in cases where the segmentation performs well.

Global longitudinal strain software upgrade: Implications for intervendor consistency and longitudinal imaging studies

Abstract: Upgrades of speckle tracking software may be associated with significant changes in GLS values, which could affect intersoftware and intervendor consistency. This finding has important clinical implications for the longitudinal follow-up of patients with speckle tracking echocardiography.
