The mean pulmonary artery wedge pressure (PAWP), left atrial dimension (LAD) by echocardiography, and PTF-V1 in the electrocardiogram were correlated with each other in 16 patients with acute myocardial infarction in the control period and after therapeutic intervention with either Dextran or furosemide and/or nitroprusside. No significant correlation was found between a normal control PAWP and the LAD. An increased control PAWP correlated well with an increased LAD (r = 0.98). No significant correlation was found between the LAD and the PAWP whether normal or elevated after therapeutic intervention. No significant correlation was found between the PAWP whether normal or elevated and the PTF-V1. No significant correlation was found between the LAD and the PTF-V1. We conclude in acute myocardial infarction 1) the PTF-V1 is not useful in assessing PAWP before or after therapeutic intervention, 2) the LAD correlates poorly with a normal control PAWP but correlates well with an elevated control PAWP, and 3) the LAD cannot be used to assess PAWP after therapeutic intervention.
在16例急性心肌梗死患者的对照期以及接受右旋糖酐或呋塞米和/或硝普钠治疗干预后，平均肺动脉楔压（PAWP）、超声心动图测量的左心房内径（LAD）和心电图中的PTF-V1相互之间存在相关性。正常对照PAWP与LAD之间未发现显著相关性。对照期升高的PAWP与升高的LAD相关性良好（r = 0.98）。治疗干预后，无论PAWP正常或升高，LAD与PAWP之间均未发现显著相关性。无论PAWP正常或升高，PAWP与PTF-V1之间均未发现显著相关性。LAD与PTF-V1之间未发现显著相关性。我们得出结论，在急性心肌梗死中：1）PTF-V1在评估治疗干预前后的PAWP方面无用；2）LAD与正常对照PAWP相关性差，但与升高的对照PAWP相关性良好；3）治疗干预后，LAD不能用于评估PAWP。
