[Myocardial blood flow in actively employed coronary cases]

In the course of coronary angiographies the blood flow of the right and left coronary artery was determined by the 133Xe lavage method in 89 patients with coronary heart disease. There was a statistically significant difference between the flow values of the LCA and RCA, while there was none between the blood flow values of blue- and white-collar workers suffering from coronary artery disease. Also a significantly better blood circulation of the right as well as of the left coronary artery was found in female employees in comparison to male employees.
