Abstract:
Objective To study the coronary artery stenosis and its myocardial function by multi-slice spiral CT coronary angiography.
Methods Sixty-eight patients with coronary artery stenosis admitted in our hospital from October 2016 to August-2017 were selected as the subjects.A total of 476(580 segments)coronary arteries were evaluated.Selective coronary angiography and multi-slice spiral CT coronary angiography were performed in patients with coronary artery stenosis.The results of coronary angiography and myocardial function were observed.
Results Two hundred thirty-two segments were detected by selective coronary angiography, including 172 mild stenosis, 46 moderate stenosis and 14 severe stenosis, 230 segment stenosis, 171 mild stenosis, 45 moderate stenosis, 14 severe stenosis and 98.74%sensitivity(P>0.05). The cardiac output(CO)(3.24±0.79)L/min, stroke output(SV)(46±11.7)ml.
Conclusion Multislice spiral CT coronary angiography is of high sensitivity in the diagnosis of coronary artery stenosis and can accurately assess the myocardial function of patients.
