[Heart-related chest pain without manifest coronary disease].

Chest pain is a common reason for consulting a physician. Although the underlying cause of the chest pain varies, the most frequent cause is coronary disease. In many cases the diagnosis emerges from the case history, the clinical picture or non-invasive examination procedures. In cases of severe symptoms or unclear diagnosis, coronary angiography is performed which often shows the coronary arteries to be patent. In a large proportion of these patients the chest pain is of non-cardiac origin. In addition to coronary disease, other heart-related conditions may give rise to chest pain.
