Long-term Results Of The Norwegian Ullevaal Model As A Cardiac Rehabilitation Intervention In Primary Care

Abstract

Exercise capacity is a strong predictor of survival in patients with coronary artery disease. Long-term results on peak oxygen uptake (VO2peak) after cardiac rehabilitation (CR) are rare. The Norwegian Ullevaal model has not previously been evaluated regarding change in VO2peak. PURPOSE: To evaluate long-term outcome of the 12-week outpatient CR intervention, the Norwegian Ullevaal model, on VO2peak and health related quality of life (HRQoL). METHODS: The Oslo HeartEx study is an ongoing single-center cohort study including all patients refereed for outpatient CR in a specialized primary care clinic in Oslo. The first 90 consecutive patients (40 after acute coronary syndrome, 35 after coronary artery bypass graft and 15 after cardiac valve or aortic surgery) attending a 12-week outpatient high-intensity exercise-based CR program (the Norwegian Ullevaal model). At entry, end, and one year after completion of the program patients were evaluated with VO2peak, weight, body mass index, blood pressure, self reported smoking- and exercise habits and HRQoL (the COOP/WONCA questionnaire). PRELIMINARY RESULTS: Long-term outcomes are available for 40 patients. Mean age was 56 ± 9 years, 85% were men. VO2peak improved significant from program entry (29.8 ±6.9 ml/kg/min) to program end (34.1 ± 7.8 ml/kg/min) and improved further at follow up (38.5 ± 8.5 ml/kg/min)(p<0.001). COOP/WONCA were significant improved in all domains (p<0.005) and clinical improved in physical improvement and change in health from entry to one year after completion. It was, however, a ceiling effect of the questionnaire regarding daily activities and social activities. CONCLUSION: These findings provide a first indication that one year after completion of outpatient CR with the Norwegian Ullevaal model, the patients still exercise and had improved or maintained their VO2peak and HRQoL.
