[Early systolic asynergia of the left ventricle as a symptom of myocardial ischemia]. / Ranniaia sistolicheskaia asinergiia levogo zheludochka kak simptom ishemii miokarda.

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.
