Abstract
In patients with coronary artery disease, the Xenon-133-elearance — introduced by Ross — has been used to investigate the coronary circulation during ergometry. This method yields maximal coronary flow rates which are considerably below the expected maximal flow rates. Using the argon method by Bretschneider, we have been able to measure the expected fivefold increase in coronary flow following maximal drug-induced coronary dilatation. This investigation is concerned with the comparison of the increase in coronary flow during exercise with the maximal drug-induced coronary reserve. An additional investigation concerns the therapeutic effect of nitrates on the hemodynamics of the coronary circulation.
