Web22 de nov. de 2024 · Basic principles. Myocardial strain describes the deformation of the myocardium from an unwound to a tense or contracted condition and can be expressed by a mathematical principle with the following formula 1-3:. ɛ = (L-L 0)/L 0 . ɛ is strain, L 0 is the baseline length and L is the length in systole. In strain imaging left ventricular … WebFor the increased wall thickness group, a score of > 5 had corresponding sensitivity and specificity values of 82% and 72%, respectively. 9 Two additional measures used were the left atrial area and the LV ejection fraction/global strain ratio that were useful to quantify the disease burden based on extracellular volume estimation by MRI.
