Exercise stress testing is the most frequently used clinical tool for assessment of coronary artery disease. To ensure a high validity of the results, a good Patient compliance is crucial. The aim of this study is to examine the effects of a virtually presented exercise group on the perceived comfort and the exercise capacity of patients during classical treadmill exercise testing. The investigators hypothesis is, that a virtually presented running group will increase the comfort of patients and their exercise capacity.
108 Patients were randomized in an open label trial 1:1 to either exercise treadmill testing while watching a static image of a flower (image group) or to exercise treadmill testing while watching a video of 5 amateur runners, running across and fields, giving the patient the impression of running within the group (video group). After the exercise test patients were asked to score their perceived comfort level and achieved level of their subjective physical limit on a 10 point scale. Standard exercise treadmill parameters, as well as baseline demographic data were recorded of each patient. Patients with missing data was excluded of the analysis. Statistic analysis was performed with t-test for normally distributed data and Wilcoxon-Mann-Whitney-Test for non-normal data.

A video of a group of five amateur runners running along woods and fields. The group was filmed from behind to give the patient the impression of running within the group.
Patients' performance
Patients' performance in metabolic equivalents percentage of age predicted maximum
Time frame: Day of Exercise Testing
Patients' comfort
Subjective level of comfort of patient during the exercise test rated on a 10 point scale. Scale ranges from 1 to 10. 10 indicates that the patient felt absolutely comfortable during the test, 1 indicates that the patient did not feel comfortable at all.
Time frame: Day of Exercise Testing

physical limits
Achieved subjective level of physical limit rated on a 10 point scale. Scale ranges from 1 to 10, 10 indicates that the patient subjectively reached his physical Limit, 1 indicates that the patient did not reach his physical limit at all. The higher the value the more did the patient reach his physical limit (the better the outcome).
