Aim To evaluate the diagnosis value of 64-row spiral CT in follow-up investigation of patients after coronary artery revascularization. Methods 28 patients underwent coronary artery bypass graft (CABG) and 114 patients underwent percutaneous coronary intervention (PCI) were performed with 64-row spiral CT coronary angiography and left ventricular function analysis. The restenosis of the grafts or stents and the variation of left ventricular function were evaluated, in the purpose of comparison of CABG and PCI. Results Patients underwent CABG and PCI got an evident increase of left ventricular ejection fraction (LVEF) and left ventricular stroke volume (LVSV). Follow-up investigation showed patients underwent CABG got a lower rate of restenosis and a better long-term curative effect. Conclusion 64-row spiral CT is of great clinic value in follow-up investigation of patient underwent revascularization.
