| Popis: | This paper describes how the clinical applications of radionuclide ventriculography have developed during the last decade. The role of resting radionuclide angiography in the assessment of myocardial infarctions, suspected left ventricular aneurysms, and the assessment of right ventricular function are discussed. Currently exercise radionuclide angiography probably represents the best way of assessing left ventricular function under stress. Extensive experience has been gained with this technique in a large number of centres worldwide. Initially the techniques were compared against coronary arteriography as the gold standard, figures for sensitivity, specificity and predictive value of the test in predicting stenosed coronary arteries were produced. This article points out that the exercise study demonstrates the physiological response of the left ventricle to exercise and not every patient with coronary artery disease can be expected to manifest abnormal physiology. Certain valuable prognostic information may be obtained from the results of the exercise radionuclide studies which may guide cardiologists as to which patients should be treated conservatively and which patients should undergo a prognostic intervention. The techniques are of major value in determining the results of both medical and interventional therapy. Abnormal ventricular function response to exercise is not specific for coronary artery disease however, and the relevance of the study must be analysed in relationship to the population under investigation. |
