In 302 patients, CHD was verified by angiography, including one branch 196 cases,two braches 51 cases,three branches 35 cases, and 20 cases with left main coronary artery narrowing respectively, whose age were 35～74 years.

CHD患者302例，年龄35～74岁，均经冠状动脉造影证实至少一支冠状动脉狭窄＞50％，其中单支病变196例，双支病变51例，3支病变35例，左主干病变20例。

During the guide wire operation, the following cares should be taken:(1) The head of guide wire needs to be bent to a certain degree and the degree of bend depends on the track of the lesion and diameter and characteristics of the vessel;(2) Insert the guide wire gently through the opening of coronary artery and ensure to deliver the guide wire into the vessel without any resistance;(3) Rotate the guide wire while delivering it across the stenosis lesion;(4) Once the guide wire is delivered to the place, no further operation should be performed before it is confirmed by angiography that the wire is in the true lumen of the vessel.

在引导钢丝的操作中应注意以下几点：(1)引导钢丝头部需弯成一定的弯度，弯度的大小应根据病变的走行、血管直径和特点来决定；(2)引导钢丝进入冠状动脉开口时，动作要轻柔，在确保推送引导钢丝无任何阻力情况下将其送入血管内；(3)引导钢丝通过狭窄病变时要边转动钢丝边推送；(4)引导钢丝到位后要造影确认其在血管真腔内，再行操作。

Methods Using the already exist coronary artery angiography as chief source,manual or auto detect the track and configuration,express themas coordinates,line,curve,ri mand modified image,then spliced them with the X-ray video as a transparent referenced matter,supply an more intuitionistic direction of Road Map to the selectivity intubatton.
