Conclusions
All in all, LV function is closely related to the degree of coronary
artery stenosis. If there is no timely intervention in the early stage
of myocardial ischemia, the LV function will further deteriorate. As a
new technique, 3D-STE can detect the changes of myocardial function
earlier in patients with TVD without myocardial infarction, and
quantitatively evaluate the global LV function through multiple global
strain parameters. This may provide a more effective method for
monitoring the change of LV systolic strain and evaluating LV systolic
function of TVD without myocardial infarction.
