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 P(w)/P(a), 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< or =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< or =1.

CONCLUSION

PDCF measurement allows quantitative evaluation of the collateral flow in patients with AMI.

摘要

目的

分析急性心肌梗死（AMI）患者压力衍生的侧支冠状动脉血流（PDCF）与Rentrop分级之间的相关性。

方法

对29例首次发生AMI且在发病后12小时内接受直接经皮冠状动脉介入治疗（PCI）的患者，通过P(w)/P(a)比值测定PDCF。将充足侧支血流（A组，n = 19）定义为PDCF>0.24，不足侧支血流（B组，n = 10）定义为PDCF≤0.24。通过冠状动脉造影评估侧支血流的Rentrop分级。在PCI术后第3天和第30天进行超声心动图检查。获取左心室射血分数、收缩末期和舒张末期容积以及相关指标。
