Patients were advised to document their steps (daily), blood pressure (daily), weight (weekly) and occurrences of a cardiac event in a diary for 1\u2009year post-CR. A Cox proportional hazard model was used to examine the influence of steps\/day, EF, gender, and age until the occurrence of an event. Kaplan-Meier curves were generated to compare patients\u2019 profiles.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Average steps\/day of patients post-CR were 7333 (SD 4426).
