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。
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 fi, action, end-systolic and end-diastolic volumes, and the related indexes were obtained. Result Rentrop grade was significantly related to PDCF （γ=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.
