摘要
目的 :探讨冠状动脉侧支循环的临床价值。方法 :对 6 8例心肌梗塞 (MI)患者进行冠脉造影及三年随访资料研究 ,其中 36例侧支积分 >1(CC组 ) ,另 32例侧支积分 <1(NCC组 )。结果 :与NCC组比较 ,CC组的多支病变及冠脉次全闭塞率较高 (P<0 .0 1) ;侧支循环及心功能较好 (P<0 .0 1～ 0 .0 5 )。两组的冠脉狭窄 ,迂曲 ,钙化程度相似 (P>0 .0 5 )。随访研究发现 ,CC组的近两年心功能优于NCC组 (P<0 .0 1) ,心绞痛及再 MI率高于 ,而死亡率低于 NCC组 (P<0 .0 1)。但两组的 MI后第三年预后相似 (P>0 .0 5 )。结论 :侧支循环存在是 MI后心绞痛及再 MI的原因 ;侧支循环对 M急性期及MI后两年内有重要保护作用 。
s: Objectives:To study the clinic value of coronary artery collateral circulation.Methods:Among 68 patients with myocardioinfarction(MI), there are 36 cases with collateral circulation integration>1(CC group),32 with collateral circulation integration<1(NCC group).Coronary angiography and follow up study were performed in all the patients.Results:Compared with NCC group by coronary angiography,the CC group had higher multiple arteries damage rate and high coronary subtotal angiolysis rate (P<0.01),more collateral circulation (P<0.01) and better heart function (P<0.05).However,the coronary stenosis tortuosity and calcification rate of the two groups were similar (P>0.05).The follow up study found that,in two years ,the CC group has a better heart function (P<0.01),higher angina pectoris and re infarction rate (P<0.01) lower mortality (P<0.01).But the groups had similar prognosis in the third year.Conclusion:The existence of collateral circulation is one of the reasons of postinfarction angina pectoris and reinfarction;CC has important protective effect in acute phase and in two years,but no protective effect for the third year.
