摘要:
目的:比较冠脉造影术(CAG)、 CAG联合冠状动脉血流储备分数检测技术(FFR)、 CAG联合频域光学相干断层扫描技术(FD-OCT)诊断冠脉临界病变无需植入支架患者,以探讨三种检查方法对预后的影响.方法:采用三种检测方案筛选冠状动脉临界病变无需植入支架患者,分为: CAG组(45例,只采用CAG检测) , CAG+FFR组(45例, CAG联合FFR检测) , CAG+ FD-OCT组(45例, CAG联合 FD-OCT技术检查) ,三组均按稳定型冠心病二级预防治疗半年,观察三组患者心绞痛的发生率(恶化的心绞痛),心肌梗死发生率、靶血管血运重建率并进行比较.结果:与 CAG 组比较, CAG+ FFR 组和 CAG + FD-OCT 组心绞痛率(33.3% 比 4. 4%、6.7%)、心肌梗死率(20.0% 比4.4%、 2.2%)、靶血管血运重建率(26.6% 比6.7%、 2.2%)均明显降低(P<0.05或<0.01) ,CAG+FFR组和CAG+ FD-OCT组间无显著差异(P均> 0.05).结论:相比单纯采用冠脉造影,冠脉造影联合冠状动脉血流储备分数检测技术或频域光学相干断层扫描技术能更有效地评估心脏血供情况,改善临界病变患者的预后.%Objective :To explore influence on prognosis in patients with coronary critical lesion assessed by coronary angiography (CAG) ,CAG combined coronary fractional flow reserve test (FFR) and CAG combined frequency do-main optical coherence tomography (FD-OCT ).Methods : Patients with coronary critical lesion who don't need stenting were screened by three detection programs , they were divided into CAG group (n= 45 , only received CAG) ,CAG+ FFR group (n=45 ,received CAG+FFR) and CAG+ FD-OCT group (n=45 ,received CAG+ FD-OCT).All three groups received secondary prevention of stable coronary heart disease for half a year .Incidence rates of angina pectoris (aggravated ) ,myocardial infarction and target vessel revascularization rate were observed and compared among three groups .Results :Compared with CAG group ,there were significant reductions in inci-dence rates of angina pectoris (33.3% vs.4.4%,6.7%) ,myocardial infarction (20.0% vs.4.4%,2.2%) and target vessel revascularization rate (26.6% vs.6.7%,2.2%) in CAG+FFR group and CAG+FD-OCT group ,P<0.05 or <0.01. There were no significant difference between CAG + FFR group and CAG+ FD-OCT group , P>0.05 all.Conclusion : Compared with pure CAG ,CAG combined FFR or FD-OCT can more effectively assess cardi-ac blood supply ,and improvement prognosis in patients with critical lesion .
