Abstract

Objective To evaluate the value of 64-slice spiral computed tomography angiography(CTA)for the assessment of coronary artery disease with hypertension.Methods Both 64-slice spiral CTA and conventional coronary angiography(CAG) were performed in 90 patients who were suspected of having coronary artery disease with hypertension.Results The sensitivity of 64-slice CT for detecting stenosis ≥50%,≥70% and 50% were 93.8%,87.5%,85.6%respectively.The specificity were 94.8%,97.6%,93.7%respectively.The positive predictive value were 91.6%,83.2%,77.2%respectively,and negative predictive value were 96.2%,98.3%,96.3%respectively.Conclusion This study suggests that 64-slice spiral computed tomography may be used as a reliable diagnostic tool for coronary artery disease with hypertension.
