The object of the study were 220 patients with a myocardial infarction, confirmed clinically, enzymatically and electrocardiographically. Seventeen indices were studied, processed via variation analysis with 8 sites of the infarction alterations. The results were compared with those in subjects with intact hearts, examined and described by the authors in another study with the aid of the same devices. The size of the maximum space velocity is most significantly decreased in all myocardial sites. The results, summed up for anterior and posterior-inferior sites are also presented. The sensitivity of some of the indices was determined as well as the correlation dependence with the level of serum creatine-phosphokinase. Highest proved to be the sensitivity of the maximum space velocity (100%), an index correlating with the level of serum creatine-phosphokinase between --0.60 and --0.64. Conclusions were drawn referring to some potentialities for a further application of the method.
