Intravital coronary arteriography has now made it possible to close the gap between the clinical symptoms of coronary artery disease and the morphological basis for them. Düx has produced the first comprehensive German treatise about it. He describes essential technical details and the results of his investigation of the function of the coronary circulation in 75 patients with pain in the chest that was either characteristic or suggestive of angina pectoris.
For the most part, Düx supports current concepts of coronary arteriography held elsewhere and recommends wider use of the technique as a routine diagnostic procedure. While he recognizes the electrocardiographic identification of cardiac necrosis and fibrosis, he refuses to admit that any method, other than arteriography, will demonstrate the extent of collateral circulation. Thus he concludes that the arteriogram provides a diagnosis of coronary artery disease earlier than other methods.
Thirteen of the patients studied were considered to have
