2019-09-02 · Peak systolic strain was defined as the maximum value of peak negative strain (myocardial shortening) or peak positive strain (myocardial lengthening) during systole. GLS by speckle tracking echocardiography was measured manually in a 18-segments LV model as the average segmental value based on three apical imaging planes.

Global longitudinal strain (GLS) measured by echocardiography is increasingly The segmental strain values are displayed on an 18-segment Figure 6 LA strain measurements with reference time point at ED (left) and at PreA (right) fo

The HUNT study by Dalen and coworkers ( 16 ) in 2009 looked at 1266 healthy subjects and gave a normal value −17.4 ( sd 2.3) for females and −15.9 ( sd 2.3) for males and showed a decrease with age. Request PDF | Age- and sex-based normal values of layer-specific longitudinal and circumferential strain by speckle tracking echocardiography: the Copenhagen City Heart Study | Aims: Technical longitudinal myocardial systolic strain by 2D speckle tracking showed far more significant LV dysfunction. Global longitudinal strain (GLS) measured 11.5% (nor-mal GLS= 18.6%)1, and regional strain values were greatly reduced in the basal and mid LV, yet preserved at the LV apex (see Figure 3). Left ventricular diastolic function measurements were 2021-04-07 · Global radial strain ranged from 35.1% to 59.0% (mean, 47.3%; 95% CI, 43.6% to 51.0%). There was significant between-study heterogeneity and inconsistency. The source of variation was sought between studies using meta-regression. Blood pressure, but not age, gender, frame rate, or equipment, was associated with variation in normal GLS values.

Gls strain normal values

Normal values for SR using STE are less well studied and therefore there is no clear clinical consensus for these values. Normal resting values of between 1.0/s and 1.4/s (SD 0.5–0.6/s) have been suggested by leading experts for longitudinal deformation . Lowest normal values of global longitudinal strain (GLS) is -17.8% in women and -16.7% in men. Strain rate: rate of myocardial deformation in time. Units are expressed in number/second or %/second. Diastolic myocardial deformation can be assessed more clearly in this way. Normal values of longitudinal LV deformation are 1 - 1.5/s or higher.

We included 147 healthy subjects (age 44.6±13.7 years, 50% female, GLS −20.8±2.0%). Men had significantly lower GLS than women (−20.1±1.8% vs −21.5±2.0%, P<.001).

Global longitudinal strain (GLS) is the most studied among strain parameters and its prognostic value has been demonstrated in several clinical scenarios. GLS was widely adapted by cardio-oncology and some studies showed that less negative GLS values at completion of chemotherapy predicted future LV dysfunction, despite normal LVEF.

Home Clinical examples Normal example 5 key points Normal value for global longitudinal strain± Reported normal values of GLS varies from -15.9% to -22.1% (mean, -19.7%; 95% CI, -20.4% to -18.9%). 2020-05-14 · In a large meta-analysis including more than 2500 healthy volunteers (mean age 47±11 years, 51% male), the normal values of LV GLS ranged from –15.9% to –22.1% (mean 19.7%, 95% CI −20.4% to −18.9%). 7 Although all were healthy individuals, clinical characteristics (eg, age, gender, body mass index and blood pressure), as well as the vendor-specific software used for longitudinal strain analysis, may explain the variation in LV GLS. The aim of this study was to assess age- and sex-based normal values for layer-specific peak systolic GLS and GCS parameters (GLS Endo,Sys, GLS Epi,Sys, GCS Endo,Sys, and GCS Epi,Sys). Additionally, we wanted to assess normal values of regional strain of the LV. Methods Population This goal has been achieved for transmural GLS, 10, 11 for which normal ranges have also been promoted in the 2016 American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) chamber quantification recommendations.

in the 3 views. For this study, we defined a normal GLS as an abso-lute value of >16%.12 All GLS measurements were performed by a single investigator, with a subset of ≈50% of the images reviewed and validated by a second reader. The intraobserver variability in GLS measurements was <10%. Statistical Analysis All data are reported as mean±SD.

proposed that a GLS value >-12% (less negative values) indicates severe systolic dysfunction or adverse prognosis; whereas a value > -15–16% indicates risk in patients with preserved LVEF.
