- W2371033401 abstract "Objective:To assess the clinic value of 40-slice CT coronary artery angiographies in diagnosing and following up coronary artery disease.Methods:897 patients,who were suspected or suffered from coronary artery disease in clinic,were examined by 40-slice CT coronary angiography with image post-processing,among them,207 cases underwent X-ray coronary artery angiography,135 cases were examined repeatedly by 40-slice CT coronary angiography after one year. The image was analyzed with its influencing factor such as age,gender,hypertension,diabetes,and hyperlipidemia. The sensitivity,specificity,positive predicted value,negative predicted value and accuracy were determined by catheter coronary artery angiography as the golden standard. Results:The good image quality rate of multi-slice CT coronary artery angiography was 94% in 897 patients. The total rate of significant stenosis of coronary artery (≥50%) was 60.88%. For the suspected patients with coronary artery disease,the rate of no plaques or plaques with mild stenosis of coronary artery (≤50%)was 56.70%(200/351)in female,and 45.18% in male respectively,χ2=7.72,P0.01. Increasing along with the age,the rate of multiple coronary stenosis raised gradually. Compared with the results of conventional coronary angiography in 207 cases,the sensitivity,specificity,positive predicted value,negative predicted value and accuracy were 84.5%,97.3%,87.8%,96.5% and 94.9% respectively for significant stenosis of coronary artery with 40-slice CT coronary angiography. Some of the calcified and non-calcified plaques were disappeared,and others occurred after one year. Conclusion:Multi-slice (40) spiral CT coronary angiography is an effective and non-invasive method to screen for suspected coronary artery disease especially in female person and follow up coronary artery plaques with significant stenosis." @default.
