OBJECTIVES: Surgically treated type-A aortic dissection patients are often restricted from physical exercise due to a lack of knowledge about the blood pressure increase. Our aims were to evaluate the hemodynamic responses during exercise, and to assess changes in peak oxygen uptake, maximal workload, and quality-of-life after completion of an exercise-based cardiac rehabilitation program.

DESIGN: Three subgroups were retrospectively identified based on their different eligibility criteria. Group I (n = 10) had performed an exercise-based cardiac rehabilitation program including exercise tests. Group II (n = 9) had followed the program without the tests. Group III (n = 10) had neither been rehabilitated nor tested. For evaluation of hemodynamic parameters, we included a group of surgically treated patients with aortic valve stenosis, group IV (n = 32). Questionnaires were obtained to measure quality-of-life.

RESULTS: At baseline the group I and IV mean systolic blood pressure changed from 143 ± 16 mmHg and 150 ± 16 mmHg to 200 ± 32 mmHg and 213 ± 27 mmHg, respectively. The group I mean peak oxygen uptake changed from 23.5 ± 7.9 ml/min/kg before rehabilitation to 28.6 ± 8.4 ml/min/kg, p = .001, after rehabilitation. The mean maximal workload changed from 143 ± 80 W before rehabilitation to 178 ± 97 W, p = .003, after rehabilitation. At follow-up, the groups I-III physical quality-of-life score was 45.1 ± 15.0, 40.0 ± 9.0, and 30.0 ± 11.3, p < .025, respectively, and the mental quality-of-life score was 51.1 ± 6, 41.7 ± 6.7, and 32.5 ± 13.3, p < .001, respectively.

CONCLUSIONS: Our results suggest that type-A aortic dissection patients have hemodynamic responses to exercise that are comparable to other cardiovascular patients. Moreover, we found significant increases in peak oxygen uptake, maximal workload, and quality-of-life after ended ECR.
