[Early diagnosis of the functional relevance of coronary heart disease].
In cases of stable or to a large extent symptom-free coronary heart disease (CHD) and atypical symptomatology, the indication for diagnostic cardiac catheterization is first confirmed by noninvasive diagnostics of ischemia. This can be carried out either with ergometric stress tests or imaging procedures in combination with ergometric or pharmacological stress. Myocardial scintigraphy and stress echocardiography are established techniques and to an increasing extent stress magnetic resonance imaging (MRI). In addition to sensitivity in providing evidence for ischemia, technical improvements in computed tomography (CT) and MRI have opened up new possibilities for visualizing coronary vessels and vascular wall morphology. While CT coronary angiography with its high spatial resolution is on the threshold of clinical application for selected patients, MRI has the potential for furnishing information on wall movement analysis, perfusion, coronary flow measurement, and plaque characterization to become the future cardiovascular "all-round examination".
