Clinical InvestigationExercise training improves exercise capacity and quality of life after transcatheter aortic valve implantation: A randomized pilot trial
Section snippets
Study design and population
Safety, applicability, and outcome of regular exercise training after SPORT:TAVI was a prospective, randomized controlled pilot trial that was conducted by 3 centers in Munich, Germany, between October 2012 and April 2014. Patients underwent TAVI either at the German Heart Center Munich or at the University Hospital Munich of the Ludwig-Maximilians-Universität, whereas the supervised exercise training was performed at the Department of Prevention, Rehabilitation and Sports Medicine, Technical
Participant flow and baseline data
The flow of participants through the study is summarized in Figure 1. The mean age of the study population was 81 ± 6 years (range, 71-92), and patients were included 83 ± 34 days (range, 42-132) after intervention. No differences for TG and UC with respect to age, proportion of females, The Society of Thoracic Surgeons mortality risk score, NYHA class, preexisting conditions, and medication were observed (see Table I). No patient had clinically relevant chronic lung disease. Participants had
Discussion
This pilot study showed that an exercise intervention in patients after TAVI, consisting of gradually increasing moderate combined endurance and strength training over 8 weeks, was safe and had no negative effects on prosthesis, renal, or neurohumoral function. It resulted in significant improvements in exercise capacity, muscular strength as well as important aspects of quality of life related to physical function, and symptom burden as compared with usual care.
Alongside interventional and
Conclusions
In this pilot study on exercise after TAVI, 8 weeks of combined endurance and resistance exercise resulted in significant improvements in exercise capacity, muscular strength, and quality of life compared with usual care without affecting cardiac adverse events or prosthesis function. The findings indicate that exercise after TAVI may strongly add to improved functional outcomes beyond the effects of the TAVI procedure itself. Adequately powered randomized trials are warranted to evaluate
