Cineangiographic contraction assessment was made in 30 coronary patients with normal left-ventricular ejection fraction. Twenty-seven (90%) patients showed abnormal myocardial segmental contractility during the early phase of contraction. or the so-called early systolic asynergia. Its loci coincided with areas supplied from atherosclerotic coronary arteries, as a result of ischemia causing local impairment of left-ventricular contractility, undetectable by routine hemodynamic investigation. In this respect, early systolic asynergia may be regarded as a sensitive angiocardiographic symptom of coronary heart disease.
对30例左心室射血分数正常的冠心病患者进行了心血管造影收缩功能评估。27例（90%）患者在收缩早期出现心肌节段性收缩异常，即所谓的收缩期早期协同失调。其部位与动脉粥样硬化性冠状动脉供血区域一致，这是由于缺血导致左心室收缩局部受损，而常规血流动力学检查无法检测到。在这方面，收缩期早期协同失调可被视为冠心病的一种敏感的心血管造影症状。
