[Quantitative functional analysis of the left ventricle in coronary heart disease. An evaluation of current methods. II. Correlation of results. Global and regional contractility parameters (author's transl)].

In the first part of the present paper, the basic methods for quantitative angiocardiography are described. In the second part, a variety of results are tabulated and discussed, derived from selective coronary arteriography, laevocardiography, left ventricular pressure measurements and heart size as seen on conventional chest X-rays. Various correlations have been derived from these. It was not possible to find an quantitative relationship between coronary sclerosis and myocardial function. The reason for this depends on the fact that the parameters derived from laevocardiography represent integrated global function. The significance of regional contractility is stressed.
