Abstract：Objective To analyze the safety and feasibility of guard wire technology during percutaneous coronary intervention (PCI) in patients with coronary ostial lesions.Methods The patients undergone PCI (n=41, male 23 and female 18) were chosen from the First People’s Hospital of Pingdingshan City from Oct. 2011 to Nov. 2015, and then randomly divided into group A (n=21) and group B (n=20). Other patients not undergone PCI (n=52, male 27 and female 25) were chosen, and then randomly divided into group C (n=28) and group D (n=24). Group A and group C were given PCI after using guard wire technology, and group B and group C were given balloon dilation and stenting after placing guide wire through target lesion vessel. X-ray exposure time, contrast agent dosage, total PCI duration, pressure incarceration times, cases of malignant arrhythmia and cases of failed PCI were detected respectively.Results X-ray exposure time, contrast agent dosage, total PCI duration and percentage of pressure incarceration increased in group B compared with group A (allP<0.05). There were no cases of malignant arrhythmia and cases of failed PCI in group A, and there were 5 of malignant arrhythmia and 4 of failed PCI. Contrast agent dosage and cases of failed PCI increased in group D compared with group C (allP<0.01). Conclusion The guard wire technology has higher safety and feasibility in the patients with coronary ostial lesions undergone PCI.
