ABSTRACT
@#Objective To evaluate the feasibility and the value of videodensitometric scale(VDS)assessing myocardial microperfusion.Methods The small coronary arteries of 11 dogs were embolized by ejecting polystyrene microbubble(dm= 100 μm),six embolized at left anterior descending branch(LAD)and five embolized at left circumflex branch(LCX).Coronary angiography was performed before and after the embolization.The myocardial contrast echocardiography(MCE)was performed in 12th hour after embolization.VDS was calculated according to coronary angiography.MCE scales were calculated.Results Among the eleven experimental dogs,VDS before embolization was 24.4±4.9 and that after embolization was 15.2±3.8.VDS after embolization was obviously lower than before embolization(P<0.05).VDS between LAD and LCX at the same stage was no difference;MCE scores after embolization were 7.6±2.4.VDS was negatively dependent with MCES after embolization(γ=-0.78,P<0.05).Conclusion As a newly quantitative index and keeping a closely correction with MCE,VDS can be used as a quantitative index to assess myocardial microperfusion in clinic.
