We examined behavioural risk factors and quality of life (QoL) in women and men, younger and older adults 12 months after a Rapid Access Cardiology Clinic (RACC) visit. Routine clinical care data were collected in person from three Sydney hospitals between 2017 and 2018 and followed up by questionnaire at 365 days. 1491 completed the baseline survey, at 1 year, 1092 provided follow‐up data on lifestyle changes, and 811 completed the EQ‐5D‐5L (QoL) survey. 666 (44.7%) were women, and 416 (27.9%) were older than 60 years of age. Almost 50% of participants reported improving physical activity and diet a year after their RACC visit. These changes were less likely in women and older participants.
