A total of 50 patients with the left coronary artery trunk stenosed by more than 50 per cent were examined. General clinical methods, ECG under physical efforts and selective coronarography were employed. According to the authors this amounts to 6.4% of all corronarographically investigated patients. A comparison of the results derived from these investigations furnished fairly reliable clinical signs suggesting the existence of the stenosed trunk prior to coronarography. The authors feel that a preliminary diagnosis of such a lesion dictates an urgent coronarography. A careful and reserved approach to the investigation and a number of modifications in the procedure used by the authors are factors substantially diminishing the risk of this investigation.
共检查了50例左冠状动脉主干狭窄超过50%的患者。采用了一般临床方法、运动心电图和选择性冠状动脉造影。据作者称，这占所有接受冠状动脉造影检查患者的6.4%。对这些检查结果的比较提供了相当可靠的临床体征，表明在冠状动脉造影之前存在主干狭窄。作者认为，对这种病变的初步诊断需要紧急进行冠状动脉造影。作者在检查时采取谨慎和保守的方法以及对所用程序进行一些修改，这些因素大大降低了这项检查的风险。
