用微分阻抗法和超声心动图比较了急性心肌梗塞患者静脉溶栓治疗１个月后梗塞相关动脉再通组２９例和未通组２８例的左心室收缩功能和左心结构变化。结果：在左心室射血分数、心脏指数和左心室射血前期间期／左心室射血时间再通组明显优于未通组〔分别是７７％±６％与７１％±１２％（Ｐ＜０．０１），２．６０±０．５６与２．４０±０．９７（Ｐ＜０．０５）和２．７５±０．０４与０．３２±０．０８（Ｐ＜０．０１）〕；但再通组左心房内径明显小于未通组（３３．５０±３．２０ｍｍ与３５．８０±３．３４ｍｍ，Ｐ＜０．０５）。
Differential impedance and echocardiography were used to compare left ventricular systolic function and left ventricular structure in 29 patients with infarction-related arterial recanalization and 28 patients in failed group after 1-month intravenous thrombolysis in patients with acute myocardial infarction. Results: The left ventricular ejection fraction, cardiac index and pre-LVEF / left ventricular ejection time were significantly better in the recanalization group than in the non-recanalized group [77% ± 6% vs 71% ± 12%, respectively <0.01), 2.60 ± 0.56 vs 2.40 ± 0.97 (P <0.05) and 2.75 ± 0.04 vs 0.32 ± 0.08 (P <0.01 ); But the left atrial diameter was significantly smaller than that of the failed group (33.50 ± 3.20mm and 35.80 ± 3.34mm, P <0.05).
