摘要： 目的测定急性心肌梗死患者压力源性冠脉侧支血流分数(PDCF),评价PDCF与传统的Rentrop分级间的相关性。方法29例急性心肌梗死患者行介入术,术中应用冠脉内压力导丝根据Pw/Pa计算PDCF,以0.24为PDCF截值将29例分为2组:A组(19例)PDCF>0.24,B组(10例)PDCF≤0.24。术后根据冠脉造影行Rentrop分级。使用统计学方法对数据进行线性回归分析,讨论PDCF与Rentrop分级间的相关性。结果Rentrop分级同PDCF呈正相关(r=0.75,P<0.01),但Rentrop≤1级的PDCF分布范围较为离散。结论冠脉内压力源性PDCF测量可对AMI时侧支循环血流作出定量评价。 

Abstract: Objective To analyze the correlation between pressure-derived collateral coronary flow (PDCF) and Rentrop grade of patients with acute myocardial infarction (AMI). Methods PDCF, determined by the ratio of Pw/Pa, was measured in 29 patients with AMI of the first onset who received primary percutaneous coronary intervention (PCI) within 12 h after the onset. Sufficient collateral flow (group A, n=19) was defined as PDCF>0.24 and insufficient collateral flow (group B, n=10) as PDCF≤0.24. Rentrop grade of the collateral flow was evaluated by coronary angiography. Echocardiography was performed on the 3rd and 30th day after PCI. The left ventricular ejection fraction, end-systolic and end-diastolic volumes, and the related indexes were obtained. Result Rentrop grade was significantly related to PDCF (r=0.75, P<0.01), but a wide range of PDCF was observed in patients with Rentrop grade≤1. Conclusion PDCF measurement allows quantitative evaluation of the collateral flow in patients with AMI.
