Assessment of positive provocative maneuvers with the presence of abnormal ultrasound or PPG results.
| Diagnostic Study | Musician Group (n = 64) | Control Group (n = 52) | ||||
|---|---|---|---|---|---|---|
| Positive EAST (n = 18) | Positive ULTT (n = 17) | Overall Positive Provocative Maneuvers (n = 28) | Positive EAST (n = 2) | Positive ULTT (n = 2) | Overall Positive Provocative Maneuvers (n = 3) | |
| Subclavian vessel compression (>50%) | 6 (9%) | 4 (6%) | 10 (36%) | 1 (2%) | 1 (2%) | 2 (3%) |
| Abnormal venous waveforms | 10 (16%) | 7 (11%) | 14 (50%) | 1 (2%) | 1 (2%) | 2 (3%) |
| Abnormal arterial PPG tracing | 7 (11%) | 5 (8%) | 11 (39%) | 0 | 0 | 0 |
| Overall abnormal ultrasound or PPG test | 15 (23%) | 14 (22%) | 23 (36%) * | 2 (3%) | 2 (3%) | 3 (6%) * |
% = percentage of patient is calculated based on the total number of patients in the musician or control group respectively. * p = 0.03 when compared between the musician and control group.
