摘要
目的:探讨冠脉病变特点,影响冠脉侧支循环(CCC)形成的因素。方法:连续收录2013年9月至2014年7月在本院心内科住院治疗择期行冠脉造影术,任一支冠脉主要分支狭窄程度≥50%的患者268例。根据冠脉造影结果分为CCC组(70例)和无CCC组(198例)。对冠脉病变特点、冠心病危险因素与侧支循环形成的关系进行统计分析。结果:(1)与无CCC组比较,CCC组的吸烟率明显降低(54.5%比35.7%),冠状动脉多支病变率(23.7%比52.9%)及重度(≥95%)狭窄率(32.3%比100%)明显升高(P<0.05或<0.01);(2)左前降支(LAD)、左回旋支(LCX)和右冠状动脉(RCA)作为供血支的比例基本相等,作为受血支RCA所占比例明显高于LAD和LCX(48.7%比32.1%比23.1%,P=0.004)。结论:1吸烟抑制侧支循环的形成;2冠脉狭窄程度及病变支数与侧支循环形成有密切关系,冠脉重度狭窄,病变支数多易形成侧支循环;3右冠闭塞几率较高也易形成侧支循环。
Objective：To explore coronary lesion characteristics and influence factor of coronary collateral circulation（CCC）formation in coronary heart disease（CHD）.Methods：A total of 268 patients,who were hospitalized in our department of cardiology from Sep 2013 to Jul 2014 and received selective coronary angiography（CAG）,and stenotic degree of any major coronary branch was≥50%,were continuously selected.They were divided into CCC group（n=70）and no CCC group（n=198）.The relationship among coronary lesion characteristics,CHD risk factors and collateral circulation formation were statistically analyzed.Results：（1）Compared with no CCC group,there was significant reduction in smoking rate（54.5% vs.35.7%）,and significant rise in incidence rate of multivessel coronary disease（23.7% vs.52.9%）and severe（≥95%）stenotic rate（32.3% vs.100%）in CCC group,P〈0.05or0.01;（2）Percentages of left anterior descending artery（LAD）,left circumflex artery（LCX）and right coronary artery（RCA）were approximately equal as blood-supplying vessel;but compared with LAD and LCX,there was significant rise in percentage of RCA（32.1% vs.23.1%s.48.7%,P=0.004）as blood-receiving vessel.Conclusion：1Smoking inhibits collateral circulation formation;2There is closely relation among coronary stenotic degree,number of diseased vessels and collateral circulation formation,the severity of stenotic degree,the more number of diseased vessels,the easily formation for collateral circulation;3 RCA occlusion rate is higher,and easily lead to collateral circulation formation.
