Abstract:
Based on 2D speckle tracking imaging (2D-STI), myocardium layer-specific strain can be used for quantitative assessment of myocardial function, but is load dependent. Added after-load (blood pressure) measurement to myocardium layer-specific strain, pressure strain loops (PSL) technique can effectively restrict load dependence and quantitatively analyze the work of whole and segmental myocardium. The research progresses of PSL in evaluation of myocardial work were reviewed in this article.
