目的 探讨严重冠脉病变侧支循环影响因素。 方法 对 79例冠脉狭窄≥ 90 %和 (或 )闭塞病变血管造影进行分析。 结果 79例严重冠脉病变有 68例见侧支循环建立 ,其中右冠病变 47例 ,伴侧支循环 44例 ,占 93 61% (44/47) ,前降支病变 5 1例 ,伴侧支循环 2 9例 ,占 5 6 86% (2 9/5 1) ,回旋支病变 2 6例 ,伴侧支循环 2 0例 ,占 76 92 % (2 0 /2 6)。合并糖尿病 39例 ,37例伴侧支循环 ,非糖尿病 40例 ,31例伴侧支循环 (P <0 0 5 ) ,合并高血压组 49例 ,46例伴侧支循环 ,非高血压组 30例 ,2 2例伴侧支循环 (P <0 0 1)。 结论 严重冠脉慢性病变多数建立侧支循环 ,以右冠病变显著 ,糖尿病和 (或 )高血压促进侧支循环建立。
Objective To investigate the influencing factors of collateral circulation in patients with severe coronary artery disease. Methods 79 cases of coronary stenosis ≥ 90% and / or occlusion angiography were analyzed. Results Seventy-nine cases of severe coronary artery disease were established in 68 cases. Among them, 47 cases of right coronary artery disease, 44 cases of collateral circulation, accounting for 93.61% (44/47), 51 cases of anterior descending coronary artery disease, There were 29 cases of bronchial branches, accounting for 566% (29 of 51 cases), 26 cases of mesenchymal lesions and 20 cases of collateral circulation, accounting for 76 92% (20/26). There were 39 cases with diabetes mellitus, 37 cases with collateral circulation, 40 cases without diabetes mellitus, 31 cases with collateral circulation (P <0.05), 49 cases with hypertension, 46 cases with collateral circulation and 30 cases with non-hypertension Cases, 2 2 cases with collateral circulation (P <0 0 1). Conclusions The majority of severe chronic coronary lesions establish collateral circulation, and the right coronary artery lesions are significant. Diabetes and / or hypertension promote collateral circulation.
