Diagnostic and prognostic value of coronary arteriography

Coronarography can be used as a diagnostic test when the clinical evaluation and the non-invasive test are inconclusive, although some conceptual problems remain. In known ischemic heart disease, the estimation of the prognosis is an important factor for the treatment decision, but coronary arteriography does not give a clear picture, and apart from the most severely ill patient, the prognosis usually remains very difficult to evaluate.
