[Indications for coronarography in selection of patients for surgery on the basis of data from veloergometry and spiroergometry]. / Opredelenie pokazanii k koronarografii v plane otbora bol'nykh na operatsiiu po dannym velo- i spiroérgometrii.

Using bicycle ergometry in combination with quantitative and qualitative assessment of ECG changes (in 605 coronary patients), and with direct measurement of oxygen consumption and systemic oxygen supply efficiency (118 coronary patients), a possibility of non-invasive assessment of the severity of coronary arterial affection prior to coronary angiography and the identification of patients with poor prognosis is demonstrated. This assessment lends a more objective foundation to the determination of indications for coronary angiography and prospective aortal-coronary shunting.
