title: [Apex cardiography in evaluating the subendocardiac blood flow and coronary reserve in a comparison with coronary radiography and bicycle ergometry data in ischemic heart disease].
abstract: Apexcardiograms (ACG) were studied in patients with chronic ischaemic heart disease in comparison with the bicycle ergometry data and coronarography. An increase was established in the coefficient A/E of ACG in lesions of the coronary vessels and in the coefficient A/EO in decreased tolerance to physical stress and in decreased coronary reserve. Despite reliable decrease of the subendocardial bloodflow index in patients with diseased coronaries no correlation between these parameters and the number and general percentage of the affected coronaries could be established. Such correlation was seen only through analysis of the duration of the period of isovolumic relaxation. In patients with the diseased coronaries a significant correlation of coefficients A/EO, A/E, AO/EO and the index of subendocardial bloodflow with the magnitude of the coronary reserve was observed.
