Abstract:
Objective To compare the accuracy of real-time myocardial contrast echocardiography (RT-MCE) with DISA-SPECT in detecting hibernating myocardium. Methods Fourteen hospitalized patients with regional wall motion abnormalities (RWMA) underwent RT-MCE, DISA-SPECT, coronary angiography and percutaneous coronary intervention(PCI). Every left ventricular myocardial segment image was acquired and evaluated according 16-segment model of American Society of Echocardiography. The Motion of every segment was observed by echocardiography after 1,3,6 months. The gold standard is that the motion of ventricular segment get better after PCI. The images of RT-MCE and DISA-SPECT were analyzed semi-quantitatively. Results The sensitivity,specificity,accuracy of RT-MCE and DISA-SPECT in detecting hibernating myocardium were 74.60%, 91.7%, 81.3% and 93.3%, 75.0%, 86.2%, respectively. RT-MCE had more value in specificity while DISA-SPECT had more value in sensitivity. The correlation between two methods was good in detecting hibernating myocardium. Conclusions RT-MCE and DISA-SPECT can be used as valuable methods to detect hibernating myocardium, the correlation between two methods is good and they have more value in specificity and sensitivity respectively.
