Abstract:
Objective To evaluate the effect of direct percutaneous transluminal coronary angioplasty (PTCA) in early stage in acute myocardial infarction (AMI) by acoustic densitometry (AD) technique Methods 40 patients with AMI were divided into 2 groups: 18 patients with direct PTCA (group A),22 patients with medical treatment (group B) The results of 2 D echocardiography and AD examination were studied on both groups at 7 days after admission Results There was no statistical difference in routine echocardiography between the two groups The results of AD examination showed: cyclic variation of integrated backscatter (CVIB) in group A was (4 2?1 3)dB, it was significantly higher than that in group B (2 5?2 4)dB ( P 0 05) Conclusion AD technology can reflect the changes of tissue characteristics in reperfused myocardia early It is a new technology for evaluating the effect of interventional therapy, predicting the improvement of cardiac function, and assessing the myocardia viability
