Echocardiography was used in the examination of 51 patients with chronic ischemic heart disease (IHD) without accompanying hypertension and congestive circulatory insufficiency. With gradual advancement of the disease, a significant increase in left-ventricular volumes during the systole and diastole was recorded as well as a decrease in the ejection fraction (IF) and velocity of circulatory shortening of the myocardial fibres (Vch) in slight variations of the stroke volume. The IF and Vch were the most characteristic indices for appraising the early manifestations of myocardial contractility disorders. The index of left-ventricular structure functioning intensity (SFI) was used to characterize the functional state of the heart muscle. In patients with a severe course of the disease, SFI was found to be reduced because of an increase in the myocardial mass. The developing damage hypertrophy, however, did not provide for full compensation of left-ventricular function and was attended by a reduction of the indices of contractility and pump function of the heart. This provides the grounds for the assumption that the reduction of SFI in patients with severe IHD is associated with exclusion of part of the myocardium involved in the pathological process from effective functioning.
超声心动图用于检查51例无高血压及充血性循环功能不全伴发的慢性缺血性心脏病（IHD）患者。随着疾病的逐渐进展，记录到收缩期和舒张期左心室容积显著增加，以及射血分数（IF）和心肌纤维循环缩短速度（Vch）在每搏量稍有变化时下降。IF和Vch是评估心肌收缩功能障碍早期表现的最具特征性指标。左心室结构功能强度指数（SFI）用于表征心肌的功能状态。在疾病严重的患者中，由于心肌质量增加，SFI降低。然而，发展中的损伤性肥大并未完全代偿左心室功能，且伴有心脏收缩性和泵功能指标降低。这为以下假设提供了依据：严重IHD患者中SFI降低与参与病理过程的部分心肌被排除在有效功能之外有关。
