PDFAbstract
Objective To analyze the value of dual source CT (DSCTA) coronary angiography in the diagnosis of PCI in-stent restenosis (ISR) in patients with coronary heart disease (CHD). Methods The clinical data of patients undergoing PCI in the hospital from July 2013 to March 2015 were retrospectively analyzed. 67 patients undergoing DSCTA and coronary angiography were selected as the subjects. The image quality of two examination methods was compared with coronary artery segment as unit, and the diagnostic value of DSCTA was identified. Results There were 70 stents in 67 patients, and 268 segments were scanned. There was no difference in image quality rank distribution between DSCTA and coronary angiography with coronary artery segment as unit (P>0.05). At the end of follow-up, 15 patients were diagnosed as ISR by coronary angiography. The sensitivity, specificity, accuracy rate, positive predictive value, negative predictive value and Kappa value of DSCTA in the diagnosis of ISR were 94.11%, 92.45%, 92.85%, 80.00%, 98.00% and 0.816, respectively. Conclusion The diagnostic efficiency of DSCTA for ISR is good and the consistency with results of coronary angiography is good, with safety.
