Follow-up at 4 months was n=12\u2009and n=17 respectively (66% of target). Median live exercise\/support session attendance was 15 (IQR 12 to 17) of 18 sessions. Home exercise bike usage was highly variable. There were two serious adverse events in each treatment arm, both unrelated to the trial. Exercise rehabilitation was considered important by participants, and trial procedures, outcomes and interventions were acceptable.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The PULSE trial procedures and interventions were acceptable, and important design considerations were identified.
