Abstract
Three aspects allow description of myocardial functional state: perfusion, motility and disturbance of structure, to all of which nuclear medicine can provide information. Distribution of /sup 201/thallium reflects myocardial perfusion distribution. Diminished accumulation of radioactive kalium, rubidium, caesium on thallium is correlated to reduced or abolished perfusion in areas of destroyed myocardial structure (infarction), the latter is marked by increased sup(99m)Tc-pyrophosphate-uptake caused by increased permeability of cellular membranes. Motility can be described globally or regionally by analysis or regional wall motion. Among global parameters ejection fraction as a measure for diminished myocardial contractility was of great interest. However, parameters for evaluation of regional myocardial motility are in the centre of interest. Camera-cinematography is the approach to analyse precordial countrate changes as time volume equivalents caused by cyclic cardial volume changes. The results allow to deliniate areas of hypokinesis and akinesis, areas of dyskinesis with phase shifting in comparison to normokinetic areas, at least evaluation of dV/dtsub(max) for contractility and relaxation. The results of normal subjects without heart disease show excellent reproducibility with strong correlation. The results of 165 patients suspected to have coronary heart disease or vitium cordis delivered additional information in part, in 27 of 29 cases results were
