Different therapeutic proportion of patients undergone coronary angiography in the era of development in MSCT

Objective To study the different therapeutic proportion of the patient populations undergone coronary angiography (CAG) in the era of development in multislice spiral computed tomography(MSCT).Methods Two hundred and fifty four consecutive patients(mean age 59.24±10.65),who underwent CAG at Daxing Hospital from February 2007 through October 2007,were enrolled,160 patients were male and 94 were female.By evaluating from the coronary angiogram,the patients were not diagnosed to have coronary heart disease(CHD) with less than 50% diameter stenosis of coronary artery;the patients to have CHD with more than or equal to 50% stenosis of coronary artery;the patients were performed the procedure of percutaneous coronary intervention(PCI) with more than or equal to 70% stenosis;the patients were proposed to have coronary aortic bypass graft(CABG) surgery with left main coronary artery lesions or diffuse triple coronary artery lesions.Results In the 254 consecutive patients,59 patients(23.2%) had not been diagnosed to have CHD;195(76.8%)to have CHD,of these patients with CHD,49 patients(19.3%)were not indicated for PCI (including the patients receiving follow-up coronary angiography after stenting),81(31.9%)had been performed the procedure of stent implantation,57(22.4%)proposed to have CABG,8(3.1%)the procedure of PCI had not been successful,or had not been performed because of patients opposing to this therapy.Conclusion Multislice spiral computed tomography can be applied as a non-invasive screening tool to exclude the presence of CHD,to increase the positive proportion of the populations with CHD in all patients receiving coronary angiograhpy,to avoid the use of CAG in a subset of patients.
