Diagnostic Value of 8-slice Coronary Angliography in Comparison with Invasive Coronary Angiography

Objective To observe the diagnostic value of non-invasive 8-slice computed tomography coronary angiography(CTA)in comparison with invasive coronary angiography. Methods clinical acute coronary syndrome(unstable angina,non ST-segment elevation of their minds and infarction and ST-segment elevation myocardial infarction)of the non-selective 54 consecutive patients with 8-slice spiral CT coronary artery imaging,there is one of two patients with coronary stent implantation or to. Selective coronary angiography results as the evaluation criteria to explore my house at 8 row MSCT diagnostic value of coronary artery disease and misdiagnosis. Results Based on segmental analysis of coronary angiography,598 coronary artery segments in 592 segments(96.7%)entered the statistical analysis,8-slice spiral CT diagnosis of coronary artery disease 81% sensitivity,the false positive rate of 13%,false-negative rate of 13%,19% misdiagnosis rate. Conclusion 8-slice spiral CT coronary angiography for coronary artery disease diagnosis and evaluation of stent restenosis have a higher value,but should not be completely replaced by coronary angiography.
