Abstract:
Objective To investigate whether non-critical coronary stenosis can be detected by coherent contrast imaging(CCI) at rest without stress.Methods Three degrees of stenosis were made in left anterior descending of 12 dogs.Myocardial contrast echocardiography(MCE) was performed with CCI and the correlation among the variables of MCE curve and the degrees of stenosis were analyzed by cubic regression.Results The time to peak was significantly prolonged with progressive coronary stenosis (P＜0.01) and related to the degree of stenosis (R~2=0.991,P＜0.001).Conclusions CCI could be used to detected non-critical coronary stenosis at rest without stress.
