【摘要】：目的评估超声冠状动脉血流成像技术(CFI)诊断冠状动脉慢血流现象(CSFP)的可行性。方法对拟诊冠心病于我院行冠状动脉造影检查,明确冠状动脉无明显狭窄且冠状动脉慢血流的患者38例,冠状动脉无慢血流的患者41例。应用校正的TIMI血流计数(CTFC)及CFI分别测量冠状动脉血流参数,对二者的相关性及CFI诊断CSFP的可行性进行分析。结果 CSFP组及对照组冠状动脉左前降支超声血流参数(PDV、MDV、PDP、MDP)分别与冠状动脉造影CTFC呈负相关。对照组VT与冠状动脉造影CTFC亦呈负相关。ROC曲线分析冠状动脉左前降支超声血流参数曲线下面积均0.7。结论 CFI能够有效、无创的反映CSFP患者冠状动脉血流的变化,对CSFP诊断有一定价值。
[Abstract]:Objective to evaluate the feasibility of echocardiographic coronary artery flow imaging (CFI) in the diagnosis of coronary slow flow (CSFP). Methods Coronary angiography was performed in our hospital. There were 38 patients who had no obvious stenosis of coronary artery and slow flow of coronary artery. Coronary blood flow parameters were measured by corrected TIMI flow count and CFI in 41 patients with no slow flow in coronary artery. Results the ultrasonic blood flow parameters of left anterior descending coronary artery in CSFP group and control group were analyzed. MDP). There was a negative correlation between coronary arteriography (CTFC) and coronary angiography (CTFC) in the control group. The area under the left anterior descending coronary artery flow parameter curve was 0. 7. ... conclusions. CFI can be effective. Non-invasive reflection of coronary blood flow in patients with CSFP is valuable for the diagnosis of CSFP.

【正文快照】： 冠状动脉慢血流现象(coronary slow flow phenomenon,CSFP)于1972年由Tambe等人首次报道,指排除冠状动脉痉挛和扩张、心肌病、瓣膜病、结缔组织病等病因后,冠状动脉造影未见明显心外膜冠状动脉狭窄(狭窄40%),而存在远端血流灌注延迟现象[1]。目前临床上对CSFP的诊断和评价的
