摘要
目的 对影响冠心病冠状动脉侧支循环形成的相关因素进行评估。方法 回顾性分析 142例经冠状动脉造影证实管腔狭窄≥ 75 %的冠心病人的侧支循环开放情况 ,以及与高血压、冠状动脉病变部位及左室后壁厚度的关系。结果 在高血压组侧支循环为Ⅱ～Ⅲ级形式的占 70 .3% ,而在非高血压组占44 .35 % ,差异有显著性 ( R =0 .36 2 ,P <0 .0 1) ;右冠状动脉病变的Ⅱ～Ⅲ级形式占 6 1.91% ,而在左冠脉病变中仅占 40 .5 1% ,差异有显著性 ( R =0 .40 0 ,P <0 .0 1) ;侧支循环开放程度与左室后壁厚度呈显著正相关。结论 冠状动脉侧支循环开放数量在高血压和右冠状动脉病变患者中明显增加 ,左心室后壁厚度与侧支循环开放成正相关。
Objective To explore the relationship between coronary collateral circulation and relative factors such as hypertension, right coronary disease, left ventricular wall thickness. Methods Analysed retrospectively coronary collateral circulation in 142 patients with coronary heart disease, which arteriostenosis were more than 75% confirmed by coronary angiography. Results Ⅱ and Ⅲgrades collateral circulation was 70.38% in hypertentive group and 44.34% in control . Ⅱ and Ⅲ grades collateral circulation in right and left coronary artery disease (CAD) were 61.91% and 40.51% respectively. There was significantly different of left ventricular wall thickness in patients with class 0 and Ⅰ collateral circulation compared with class Ⅱ and Ⅲ. Conclusion Coronary collateral circulation is increased in patients with hypertension or CAD, and is positively correlative to left ventricular wall thickness.
