Abstract

Background: Physical activity (PA) and cardiac rehabilitation (CR) attendance are important for recovery and prognosis following acute coronary syndrome (ACS). However, PA patterns early post-ACS are not well known.

Objectives: Investigate the level of PA at 4-weeks post-ACS and any potential associations with CR enrolment.

Methods: We recruited patients admitted for ACS from cardiac wards and clinics at two hospital sites in Sydney, Australia. PA data were collected using wearable activity trackers worn at 4-weeks post-ACS, and CR enrolment was self-reported.

Results: Participants (n = 61) were aged 66.7 ± 10.3 years, 74 % male, 61 % were married or partnered, and 33 % were diagnosed with ST-elevation myocardial infarction. Patients engaged in 7514±3355 steps per day and 44.6 ± 37.5 min of moderate-to-vigorous physical activity (MVPA). Patients who enrolled in CR exhibited higher daily step counts (p = 0.044), MVPA minutes (p = 0.001), and were more likely to meet PA guidelines. ACS patients who engaged in higher levels of MVPA were more likely to enrol in CR (odds ratio [OR] 1.46; 95 % confidence interval [CI] 1.08, 1.98). CR enrolment was also positively associated with being married or in an intimate partnership (OR 9.93; 95 % CI 1.83, 53.85) and absence of depressive symptoms (OR 11.86; 95 % CI 1.91, 73.74).

Conclusion: Lower CR enrolment rates were observed among less physically active patients at 4-weeks post-ACS. However, each 10 min increment in MVPA increased the odds of CR enrolment by 46 %. Future research should explore strategies to target this inactive and high-risk group, given the potential for a large prognostic gain with CR participation.
